Carbohydrates for Fertility and Health

Carbohydrates for Fertility and Health

I spend a disproportionate amount of my time telling women to eat carbohydrates.

In the paleosphere, it is incredibly common to eat a low carbohydrate diet. Plenty of people use low carbohydrate diets to lose weight, to sharpen insulin sensitivity, and to reduce appetite in the short term.

A low carbohydrate diet can also be therapeutic for people with cancer, migraines,and  chronic infections or psychological disorders.

On the other hand, low carbohydrate diets can be a significant tax on people, women especially.

Because low carbohydrate diets are so popular for weight loss, it is common for women trying to lose weight and to “look good” to exercise often, eat very few carbohydrates, fast, and restrict food intake.  The more of these restrictions a woman undertakes at once, the more and more her body reads this as living in a starved, stressed state.

The effects of this are significant: adrenal glands work overtime, livers get tired from performing so much gluconeogenesis, insulin sensitivity drops, body fat levels fluctuate, sleep quality decreases, and libido and fertility decrease.

The problems that come from a low-carbohydrate diet of course don’t affect every woman. Each of us is different. But women who experience stalled weight loss, low-thyroid symptoms, menstrual dysregulation, sleep and or mood and mental health related issues may find significant relief from adding carbohydrates back into their diets.

If you are trying to lose weight, take a look at my program, Weight Loss Unlocked, which will help you lose weight in a healthy, safe, and balanced way. Check it out here.

Also, this is my favorite paleo cookbook with plentiful carbs in it. It’s by Russ Crandall, and he’s an amazing chef, as well as one of my favorite people of all time.

Carbohydrates are beneficial for fertility and health because…

-Glucose is necessary for the conversion of T4 to T3 in the liver.

Without adequate glucose, the liver struggles to make enough T3, which is the form of thyroid hormone critical for healthy thyroid function.

Without sufficient T3, hypothyroidism results. Hypothyroidism is implicated in mood disorders, reproductive irregularities such as PCOS and amenorrhea, in skin conditions, and in weight gain, among other things.  (For more on how to figure out your particular type of PCOS and how hypothyroidism may be at play, see my program PCOS Unlocked or read my post on the causes of PCOS)

Many women, contrary to popular paleo belief, in fact lose weight once they add carbohydrates back into their diets. This is because the carbs help the body produce more T3.

(Now, low carb dieters might be quick to point out that the liver can manufacture its own glucose. Certainly, the liver is capable of producing its own glucose with gluconeogenesis, but that process can become taxed over time, particularly if the liver is already taxed from poor eating habits in the past, mineral deficiencies, stress, or calorie restriction.)

-Glucose elicits an insulin response, which in turn spikes leptin levels in the blood.

This is a short-term spike, so eating carbohydrates should not be used as a replacement for body fat, which is the primary long-term secretor of leptin.

However, moderate, regular consumption of carbohydrate spikes leptin frequently enough to help signal to the hypothalamus that the body is being fed. Leptin is absolutely crucial for reproductive function.  Without leptin, the hypothalamus does not tell the pituitary to produce sex hormones, so it doesn’t.

Insulin is also an important signaler of the “fed” state. 

In addition to leptin, the hypothalamus also responds to insulin. These two hormones are largely responsible for the female body determining whether it is in a “fed” state.

Being in a fed state is critical for convincing the body it is in a healthy enough environment to reproduce, have a libido, and also lose weight.

Moderate carbohydrate intake is associated with better mood, stress-reduction, and sleep quality.

I see this in my work and in anecdotes, as well as in many controlled studies.

Carbohydrate intake boosts tryptophan levels in the brain, and tryptophan is the protein precursor to serotonin. Getting at least some carbohydrate in the diet helps with the vast array of issues associated with serotonin deficiency which include moodiness, stress, and insomnia. People have been shown to sleep better if their dinner includes carbohydrates in it.

This is especially true for women.

For a look at the details and complexities of the issue, see Emily Deans writing  here and here. The primary takeaway of this point being that while the exact mechanism of carbohydrates boosting mood and sleep quality is unknown, carbohydrates still appear to be a healthy, and in many cases necessary, macronutrient.

Carbohydrates for fertility and health

The main point here is that carbohydrates are not just okay but important. For women who have appetite control problems, sugar addictions, and a lot of weight to lose, absolutely I believe a low-carbohydrate diet can do them wonders. For women who struggle with menstruation, fertility, stress, exercise performance, or any other hormonal oddities, carbohydrates help assure the woman’s body that she is healthy and fed.  This is crucial for reproductive health.  

In all cases, diet is a matter of personal physiology and experimentation.  If a woman’s body works better on carbs, she should eat them, and delight in those joys rather than worry needlessly.  At the very least, they are not harmful, and at their best, they are life saving.

This concept is central to my program Weight Loss Unlocked. If you are interested, it will help you figure out which path to weight loss is best for your unique body and metabolism.

Carbohydrates to eat:


-Starchy tubers such as sweet potatoes, batata, jerusalem artichoke, cassava, tarot, and bamboo. Regular potatoes are fine, too, but they contain fewer vitamins than their sweet counterparts.  Of the sweet potatoes, Japanese sweet potatoes are the most delicious, in my opinion, followed by white sweet potatoes and then yams and regular orange sweet potatoes.

These starches are composed primarily of glucose.

Fruits. All fruits! Berries and cherries tend to have more glucose than fructose, other fruits tend to have more fructose than glucose. This is not a huge point of difference but I have noticed that some women tend to do better on glucose-heavy or fructose-heavy carbs. I personally have an easier time with weight maintenance with fruits than with starches. I talk about this idea more in depth in that Weight Loss program for women I use with my clients.

-Rice Both white and brown rice are fine, but are fairly nutrient-poor.

Brown rice contains anti-nutrients in it’s shell, so white rice is more innocuous in terms of nutrient absorption.  Wild rice is another option that I like.  Pink rice is something that my friend Noelle from Coconuts and Kettlebells really loves and is a unique way to incorporate rice into the diet! (By the way, if you haven’t listened to The Paleo Women Podcast featuring myself and Noelle, you need to!  We are the BEST and we will explain to you ALL THE THINGS.  Find us here!)

-Vegetables of course are great, but they do not count for carbohydrate consumption.  I know that most of the carbs in vegetables are glucose, but much of it them are also tied up in fiber, which is broken down and turned into short-chain fatty acids by gut bacteria. For this reason, vegetables alone cannot make up a woman’s carbohydrate consumption.  Instead, starchy tubers and fruits work the best.

How much carbohydrate to eat for women:

For a woman recovering from stress, metabolic distress, and hypothalamic amenorrhea, I recommend eating between 100-200 g/day.  That goes for athletes as well. And for pregnant women. At least 100 g/day.

I typically recommend that women start with 100 grams of dense carbohydrate like starches and fruits and experiment from there. You can definitely eat more than that – I know that I do. But you could also eat a bit less, especially if you prefer a lower carbohydrate appraoch to health.

Remember, you do not necessarily need to eat high carbohydrate. You can, but you don’t have to. It is only that a diet with at least some carbohydrates can really help with fertility, hormone balance, thyroid, and weight loss problems.

Book Review: It Starts With Food by Dallas and Melissa Hartwig

Book Review: It Starts With Food by Dallas and Melissa Hartwig

Let me begin my review by stating outright that I don’t like most books, philosophies, and things.  It’s a matter of quality in a vast variety of realms.   Intelligence, rationality, common sense, scientific-coherence, clear communication of ideas.  Love, feminism, equianimity, no-nonsense approaches to life.   Hard-hitting and real and down-to-Earth all at the same time.  These are a few of my minimum standards for acceptability.

I don’t like most books.

I love It Starts with Food.

The rockstar couple of Dallas and Melissa Hartwig wrote this book like they meant it, and, god damnit, it shows.  

Melissa and Dallas approach food in a way that optimizes the best of all worlds.   Food is not a convenience; it is not an indulgence; it is not an enemy.  It is not even medicine, in that certain foods are not proscribed for healing particular ailments.  Instead, food is nourishment.  Food is a blessing.  And food, when interacted with properly, assures all people–no matter how sick and fatigued they might be–the health, confidence, energy, and vitality that each individual has the potential to realize, but that has gotten so lost in the modern world.

It Starts with Food is based on the premise of four “good food” standards.  These standards must be met by all allowed foods, and if the standards are compromised in any way, the food needs to be eliminated (at least in the strict 30-day “clean” phase of the Whole30 program).   This may sound alarming at first– that probably eliminates a lot of foods!– and many might cry.  And sure, if you consider things like Whoppers and Snickers as food, then it does eliminate a lot.  These principles do not, however, eliminate anything that nourishes, anything that is real, anything that comes from the Earth and can be plucked (or butchered) right from the grounds of a local farm.

These four food standards are:

1) That the food promotes a “healthy psychological response.”

2) That the food promotes a “healthy hormonal response.”

3) That the food supports a healthy gut.

And, therefore, 4) That the food supports healthy immune function.

These four food standards, and the order in which they fall, are the precise reason that I love and advocate this book so fiercely.   I’ll get to that in the bulleted list below.  First, I’ll air my “critiques” –if in fact they can really be called as such.   They’re honest, but minimal, and anyway no review is critique or believable without them.  Secondly I’ll list all of the delightful things to look forward to in It Starts with Food, and why this is the perfect book to get someone moving on the path of self-healing and -love.

Points of difference/critique:

  • Some things in the book that are relevant for health are glossed over, such as fitness, sunshine, and sleep.  More than anything I would like to see sleep addressed.  However– the title of the book is It Starts with Food, so we can presume that the book is going to be about Food first and foremost.  I appreciate this focus, and honestly poor food choices are the primary reason everyone’s in this mess anyway, so it’s appropriate to be real and address this issue first.
  • Seed oils were not quite villianized enough for my tastes.  Though they do receive their own chapter of concern, later on in the book the big things to be avoided are always “grains, sugar, dairy, and legumes.”  Legumes are much more innocent than O6s, in my opinion.
  • Fiber!  The Hartwigs advocate fiber.  Disagree!
  • Re-introduction of toxins.  The Hartwigs start bringing things back into the diet on day 30, starting with dairy for three days, then gluten grains for a day or two, etc.  While this may work on a short-term evaluative basis, for people with hormonal issues, the negative effects of these products are far more long-range and far more insidious.  For example, for women with androgen issues, I would never recommend putting dairy back into the diet, especially at 30 days.  It takes months for hormones to readjust to different diets.  However, the Hartwigs do caution about longer-term effects, so kudos to them for hitting on this important point.
  • Caveats for “paleos not working” and “help!”  I would have liked to have seen more instruction for people who still struggle after the Whole30 with their health.  Dallas and Melissa instruct people to hold onto the program longer, but there are also specific health (mental and physiological) issues that endure through a paleo diet and need to be addressed in a specific and perhaps separate way (a la the hormone issues I mentioned above).    On the other hand, the Hartwigs do have a whole chapter on “special populations” and recommend that people with real health conditions consult their doctors and remain in conversation with them as they move forward.

as for the meat of the book, and why I enjoyed it so thoroughly:

  • ‘Tough’ love.  The Hartwigs are full of love and encouragement and sympathy.  It’s amazing.  What’s even more amazing is how they manage to integrate this with lighting a hard-lined, radical fire in your soul.  “It is not hard.” They write.  “Please don’t tell us this program is hard.  Quitting heroin is hard.  Beating cancer is hard.  Birthing a baby is hard.  Drinking your coffee black . Is . Not. Hard.”  Food cravings are a nightmare, and certain situations and health problems are frightfully challenging, but the approach the Hartwigs take to this issues–that of positive strength, steadfastness, and encouragement–disarms the power of toxic foods, and in turn encourages an individual’s belief in her ability to do it.
  • Honesty.  The Hartwigs tell their readers straight up the limits of the research, and encourage experimentation and skepticism.
  • The world’s most accessible analogies.  I’ve gone through this science with a fine tooth comb several times, but I still found their analogies helpful.  Some examples include the immune system as firefighters, intestinal lining as human skin, in that abrasions permit the passage of toxins, and eating meals properly is likened to becoming accustomed and then automated to driving a car in driver’s training.  Brilliant, accessible, and yet scientific to a T.
  • Explanatory sidebars and diagrams.  The sidebars are a huge help, and enable the Hartwigs to deal with complex issues without fuddling around in the details.  Definitions, specifications, and clarifications are all designated special spots in sidebars that are super helpful.  Diagrams are simple and easy to understand.  Sidebars also include practical tips.  For example, getting sunflower oil instead of peanut oil for peanut butter, or talking about celiac and gluten with respect to wheat proteins.
  • Humor.   The Hartwigs are great.  Hard-hitting, sarcastic, and down-to-Earth all the while.  EG, regarding protein portion sizes:  “Also, for the record,” they write, “one and two sized palm portions are not your only options. You’ve also got 1.25  palms, 1.5 palms, 1.942 palms, and every possibility in between.  This should not be overwhelming.  You all have palms.”
  • Simple food plan.   The food plan is awesome: one palm of protein, fill the rest of the plate with vegetables.  “Um, that’s it.”   And then adding in thumb sizes for the fats.  Honestly– as someone who has spent the last ten years of her life trying to figure out how much to eat and when, it’s surprisingly helpful.
  •  Food quality.  The Hartwigs emphasize food quality, particularly the quality of animal foods, as the primary aim of nutrition.  That’s so important.  So often people let conventional meat-buying go by unmentioned, but it really is problematic in the long-term, especially for people with hormone problems, and any kind of liver burden and toxicity.
  • Radicality.  The Hartwigs insist on being completely clean for the Whole30.  They’re not throwing punches.  They are serious about health.  If you want to get better, you need to avoid food toxins for at least 30 days.  Thank you, Dallas and Melissa, for bringing that reality to people in an accessible, loving, empowering way.

And for the aspects of the book that make it truly fabulous, and the best diet book I have ever read:

  • Stress.  The Hartwigs beg you not to stress about your food.   Stress is psychologically but also physiologically important.  While they’ve thrown lots of science, concerns, and diseases at their readers, in the end all they want is for you to undertake a life of eating real food, and to relax into and trust that decision.
  • The eating experience.    The “how” of eating is important.  The Hartwigs encourage their readers to think of eating as a “nourishing experience.”  Nourishing!    Yes!  Moreover, I love how reverently they talk about food and the eating experience.    For them, eating is about focusing on a single pleasure, taking a break out of the day, preparing food for and treating one’s self, relaxing into and enjoying the gift of nature’s brilliance.
  • Restoration of health and hormones as the true path to health.    The Hartwigs don’t tell their readers how much to eat or how much of anything to eat because the point of it all is to trust in natural hormones.  I love this.  This is what I believe about food, and I am so glad to see it trumpeted.   Bodies are designed to work, and treating them well and with the proper nourishment is all most people need in order to heal, slim down, and become radiant, energetic beings.   “In addition,” they write, “you won’t be weighing, measuring, or tracking your calories at all.  We think those are all unnatural, unsustainable, psychlogically unhealthy processes that take the joy out of food and eating.”  And in the end, they assert that hormones are more important than calories, that it is okay to be uncertain at the outset–but that trust is crucial because if we cannot trust natural foods and our bodies, what can we trust?  “For perhaps the first time in your life, you can rely on your body to tell you what it needs.”
  • The emphasis on health, particularly on psychological health.  This is the most important point of the whole book.  The first of the good food requirements is that the food be psychologically satisfying.  This is amazing and so important, and I am so so so so so happy about this book for this reason.  A healthy body is nothing without a healthy mind.   The Hartwigs emphasize psychology with this food category, but it doesn’t stop there.  Throughout the whole book they caution against stress, they advise their clients to never step on a scale, they speak directly to food cravings and disordered eaters, and they don’t use the word “cheat” because eating should always be guilt free.   Amen!  Their diet is not a diet, it is not about restriction, and it is not even about losing weight.  So many diet books out there slap the “lose weight!” subtitle onto a book in order to sell more copies, and the Hartwigs do mention weight loss (because it happens! automatically and unintentionally in 95 percent of their clients!), but they don’t really care.  What they care about is health.  And with health, a healthy weight always follows.
  • Love.  The fire and passion Melissa and Dallas have for their work are obvious over and over and over again throughout this book.    It shows in how reverently they talk about food and the eating experience, in their fire and their tough love, and in their affinity for and closeness with all of their clients.  Thank you, Melissa and Dallas, for caring so much about people and their holistic health to go through the trouble of putting together this fantastic book.

I do not like most books about food.

But this book–It Starts with Food–by Dallas and Melissa Hartwig, being released this June 12, 2012– is full of excellent science, easy to follow plans, an emphasis on real, vital health, psychological well-being, passion, humor, reverence, relatability, and love.    I would really like to see a bit more love and attention for people for whom the program does not work wonders, but the general message of positivity, progress, and love, and their unique and powerful emphasis on psychological health earns the Hartwigs six million stars.

Paleo and Amenorrhea: How Extremity Can Make even the Best Diet Fail

Paleo and Amenorrhea: How Extremity Can Make even the Best Diet Fail

The volume of emails I receive from women who start having menstrual problems on a paleo diet is staggering.    It is not an enormous volume, no.  But it is enough to give a woman pause.  What gives?  Aren’t we supposed to be healthier on a paleo diet?

Yes, we are, and really, we are.  In the vast majority of women who eat a Standard American Diet, specifically those who are overweight, a paleo diet does wonders for balancing hormone levels.  It is usually only when a paleo/whole-foods diet is coupled with restrictive norms that women start running into problems.  Too little food, too much exercise, and too much stress are really what it all boils down to.   The whole foods are not to blame– not in the slightest.  What are to blame, instead, are the obsessive ways in which people interact with these foods.

There are several mechanisms that may be at play in the physiology, depending on each woman’s genetics and how each woman undertakes her paleo diet and lifestyle.

What happens in the body when it stops menstruating

The female reproductive system runs off of a sensitive fleet of circulating hormones.   When one or several of them is disrupted, many of the others fail at their jobs, too.

During the menstrual cycle, hormone levels in the blood signal to the hypothalamus to signal to the pituitary to release FSH and LH, two hormones that in turn tell the ovaries what to do.    FSH–follicle-stimulating hormone– is released in the first part of the menstrual cycle to incite egg development.  LH–luteinizing hormone–is released in the second part of the cycle and prepares the endometrium to be shed.  Without proper FSH and LH levels, the female body can never convince the ovaries to do their job.  FSH and LH are crucial, and they rely on proper functioning of the HPA axis.

This job of the ovaries is to produce the follicles and the eggs, but in doing so it also produces estrogen and progesterone.  This fact is important for signalling menstruation, because it is partly the rise and fall of estrogen and progesterone levels throughout the month that signal to the hypothalamus to release FSH and LH at different times.   This is, in essence, a circle of signalling.  LH and FSH from the hypothalamus to the ovaries, estrogen and progesterone back to the hypothalamus, and so forth.

Hormone malfunctions that cause amenorrhea

Decreasing estrogen levels stop the pituitary from being able to send out FSH and LH.

Decreasing leptin levels stop the pituitary from being able to send out FSH and LH.  This is because decreased leptin levels signal to the hypothalamus that the woman is lacking energy stores and is, in essence, starving.  When the hypothalamus thinks the woman is starving, it puts a halt to normal reproductive functioning.  Leptin levels decrease proportionally with fat mass decreases.   On the other hand, leptin can also go undetected when an individual is leptin insensitive.   Insensitivity is in general a larger problem for overweight women, and low absolute leptin levels are in general a greater problem for thin women.

Increased testosterone production interferes with estrogen levels.

Increased stress and cortisol levels put a halt to hypothalamic and pituitary function.

Cause 1: Weight loss

Both estrogen and leptin are produced in fat cells.  These are the two blood serum hormone levels necessary to signal to the hypothalamus that a woman is fed and happy, and that it should go ahead with normal reproduction.   Without these two hormones, reproduction ceases.  It is well known in the medical literature that the low body fat of anorexic women, models and athletes is what accounts for their amenorrhea.   Without fat, a woman simply cannot menstruate.

What is discussed less often in the literature, but is still true (see Wenda Trevathan’s Ancient Bodies Modern Lives) is the fact that a woman’s reproductive system is set up to run on the nutrient basis she has as a young girl.  Throughout puberty, if a girl has a higher-than-average or higher-than-healthy body fat percentage, her ovary to hypothalamus signalling may develop as ‘handicapped’ by these fat stores.    Because fat cell estrogen is so high, the ovaries do not have to produce as much.   For example: If the body’s estrogen set point is 100 units, and fat cells produce 80 units, then the ovaries only need to produce 20 units.  Then, if the woman loses weight, the set point remains around 100 or falls a bit to a healthier level (unique to each circumstance), and the fat cells production falls to around 30 units, such that estrogen from the ovaries is then expected to make up for the rest of the estrogen deficit.   Many women have no problem with this. Their ovaries jump into higher gear.   Many others, on the other hand, do struggle.  Their ovaries never end up rising to fill that gap.  The thing is– the set point is not stuck precisely at 100.  It will decrease to a healthy level.  But it might not decrease as far as a woman bent on meeting social expectations of body image is hoping.

The alignment of a woman’s sex hormone levels with the amount of nourishment she has during puberty accounts for why women who live their whole lives on the edge of starvation can still have babies, but women whose body fat percentage decrease from 28 to 21 cannot.

This is not to say that an overweight woman will stop menstruating when she loses weight.  Each body is capable of menstruating within the healthiest range of body fat percentages, from around 20 percent to 30 percent.  But a woman who has always erred on the side of heavier might  find that she cannot dip below 23 or 24 percent body fat without losing her period.  23 or 24 percent body fat is healthy, so this is fine.  It might not fly is the woman is trying to meet ridiculous standards of Western body image, but it is optimal for her to have the appropriate serum hormone levels.

Other factors that can hurt estrogen and leptin signalling may also play a role.  If a woman can correct those, then she may be able to decrease her body fat levels without hurting her reproductive system.  For example, chronic stress hurts hypothalamic signalling.  So a stressed out overweight woman is going to have a harder time with reproductive fitness while losing weight than a totally relaxed overweight woman.  This is a fact.  For menstruation to take place, estrogen and leptin levels must be high enough.   Body fat plays a significant role.  There are some other factors that can be addresssed and help as well.

Cause 2: Exercise

Weight loss can cause decreased leptin signalling, but exercise can, too.   Body fat is the major player in leptin levels, but energy deficiency in general hinders leptin.  When a woman is burning more calories than she is consuming–or when she is burning a high quantity of calories while under emotional and physical stress–her body calls it quits.  Instead of directing energy towards reproduction, it conserves it for other functions.

Cause 3: Low Calorie Diet

A low calorie diet performs the same function as both weight loss and exercise.  It stresses the body and puts the woman in a state of energy deficit.  The hypothalamus does not like being in energy deficit, so it tells the ovaries to stop working until it can get itself out of the energy deficit.

A low calorie diet is more of a problem for thin women than it is for women trying to lose weight.  Leptin levels first and foremost are reliant on fat stores.  The body can eat it’s own fat.  That is in fact how weight loss occurs.   So if a woman is eating her own fat, she is not starving.  Once her body fat levels dip too low, however, and if she is maintaining a low-calorie, starvation-type diet, then she may stop menstruating.

Cause 4: Low Carbohydrate Diet

Many, if not most, women have a real need for carbohydrates.  This cause is the most common cause of amenorrhea in the paleo world next to weight loss, in my experience.

Carbohydrates are necessary for the conversion of T4 into T3 (the active form of thyroid hormone) in the liver.  The liver is capable of producing its own glycogen when it’s not being fed sugar, but this process can become fatigued over time, especially if the woman is under any kind of stress, or restricting calories, too.

Hypothyroidism, or sub-clinical hypothyroidism, is one of the primary causes of ovarian malfunction.  Without sufficient levels of T3, organs shut down, and the reproductive organs are the first ones hit.  Without T3, estrogen cannot be produced, and follicles cannot develop.  Without T3, a woman cannot menstruate.

For this reason, many paleo women supplement their diets with iodine and find that their amenorrheic symptoms ease.  However, many others do not.  Instead, they have to add carbohydrates back in to their diets.

Another role that carbohydrates play is spiking leptin levels.  Whenever insulin spikes in response to blood glucose, leptin levels rise, too.  This means that carbohdyrates help signal to the hypothalamus that the woman is fed.  However, this is a short-term elevation.  It only spikes in bursts and with meals, so it cannot be used as a long-term solution to health.  It is important to note, however, that a high fat, low carbohydrate diet is consistently associated with the lowest leptin levels possible.

Cause 5: High-Dairy Diet (an influence, at least)

Dairy is full of hormones.  Even cows raised on pasture cannot help but produce certain hormones that influence a woman’s reproductive system.   Dairy is the most androgenic food.  It contains a protein that inhibits normal inhibition of testosterone in an individual’s body, such that when someone ingests dairy their testosterone levels can rise unchecked.  This is in fact why so many people experience acne when they eat dairy.  Even men.  It really can increase testosterone levels that much.

Moreover, much of the dairy consumed in today’s world is not organic and grass-fed but is instead choc-full of unnaturally injected hormones.  Farms and the US government are touchy about telling the public what goes into their animals, and they claim that these hormone profiles are insignificant.  However, anecdotally, myself and with some other women, it seems as though these hormones really can influence women who already have compromised reproductive function.  Conventionally raised animals can cause real problems.  This goes for dairy, and this goes for eggs and meat products as well.

Cause 6: Altered Phytoestrogen and Hormone-Ingestion Profile

This cause is related to the cause above.   We ingest hormones on a regular basis.  With a healthy reproductive system, this is not a problem.  Hormones from food are far less potent than hormones from the ovaries.  Please keep that fact in mind.   A healthy reproductive system has very little problem with phytoestrogens in foods.  But some women have struggling reproductive systems for one reason or another, and they need to be aware of what hormones they have been and what they are now consuming.

Phytoestrogens are plant estrogens.  They look a lot like estrogen, but are not identical.  This is why phytoestrogens should never be consumed as a replacement for estrogen.  Sometimes they relieve certain symptoms of estrogen-deficiency such as hot flashes, but they also fail to act exactly like estrogen does in the body.  This means that other signals and connections are not being made, potentially crucial ones.  Hot flashes may cease, but acne may continue to run on unchecked.   And other problems can ensue.  For example, breast cancer.

Phytoestrogens are primarily in legumes, nuts, and seeds.  Soy is the most potent phytoestrogen, and should be avoided at all costs.

There are other sneaky ways in which hormones can infiltrate a woman’s diet, especially if a woman undertakes a paleo diet with compromised reproductive function and inattention to the quality of her food.  For example, if a woman goes on an egg-heavy diet when starting paleo, but the chickens are fed a soy rich diet,  she is actually eating a soy-rich diet.  This is not normally a danger, but with a compromised reproductive system and a soy- or hormonal- influence from poorly treated animal products, it is worth taking into consideration.

These effects, I need to emphasize again, are not usually relevant for women with healthy reproductive systems, and should only be considered in severe cases. Only when hormone levels have dipped so low or have skyrocketed so high that the body becomes sensitive to these normally tolerable and easily managed fluctuations from food.  Certainly, conventionally-raised cows are not optimal, but I would not discourage anyone from eating them (in terms of their health) at all if they have no other options.  Sincerely.  Far, far more important is the quality of hormones being sent through leptin and estrogen signalling within the body.

Cause 7: Stress

The final cause should come as no surprise to anyone.  Stress halts reproduction: stress from toxic foods, stress from eating disorders, stress from social life, stress from exercise, stress from work, stress from existential despair… the list is vast.  The physiological result of all of the possible stressors is roughly the same, however.  Cortisol levels rise and these levels prevent the hypothalamus from sending the appropriate reproductive signals to the ovaries.   This may, in fact, be the most important of all the factors I’ve discussed.  There is no way to quantify it, and it burns ubiquitously throughout the Western world.  What if all of us calmed down?  What if we all lived in harmony, and peace, and did not fret?  Stress is significant, and stress is real.  Hundreds of thousands of American women do not menstruate because they are stressed.  How many more experience hindered reproductive function because of stress?  I suspect the number lies in tens of millions.

The Evolutionary Perspective: Liberating and Empowering a Woman’s Self-hood

The Evolutionary Perspective: Liberating and Empowering a Woman’s Self-hood

The modern notion of womanhood, in which women eat little, exercise a lot, have eating disorders and body image issues, and are expected to look like rails, fails women time and time again.   The solution to that failure–to all of the pain, to all of the confusion, and to all of the self-loathing in modern America–is to adopt an evolutionary perspective.

Adopting an evolutionary perspective with respect to diet means looking at evolution and trying to align modern practice with what women’s bodies were designed for.  It does wonders for health.  A paleo diet (though not a specific diet, but rather the template in which to experiment and exist) is the only cure, really, to the disconnect that has emerged between a woman and the natural programming of her body.

Yet the paleo diet I advocate falls under a larger umbrella of perspective and meaning.   This is why what I really advocate is the evolutionary perspective more than anything else.  The evolutionary perspective includes eating the proper foods, but it really is so much bigger than that.  It’s about naturalness, about outlook, and about real, proud, embodied womanhood. There are specific aspects of an evolutionary perspective beyond the physiological that arise out of and are necessary for living this way.  What follows in this post is an articulation of what I think those roles and benefits are.


With an evolutionary perspective, a woman does not work against but instead works with her body.  She understands that her hormones are designed to maintain a healthy body.    She understands that her body is programmed for optimal fitness and fertility.  She understands that war is not the answer.  How could a war ever be sustained?  How could victory ever truly be won?  Is there such a thing as winning, and if so, at which price does it come?  That is a scary question, and its one that many of my readers face.  The price of war is eating disorders, body image issues, amenorrhea, infertility, acne, hair loss, fatigue, depression, anxiety, and eventual weight gain.  The answer is instead discerning the foods that the body truly needs, and feeding it those so that it can do its own job.

With an evolutionary perspective, a woman listens to her body.  An evolutionary woman undertakes eating and lifestyle choices that optimize how good she feels, her health, and her well-being.  She does not feed her body toxins.  She does not run it into the ground with excessive exercise.  She does not spend all day hunched over in an office chair under the unrelenting glare of florescent lighting.    These things she knows are not good for her.  They do not feel good, either.  What then really does make her feel alive, embodied, sexy, and powerful?   In order to know, she must listen.

With an evolutionary perspective, a woman does not see herself as separate from her body.  There is no need to fight.  In fact, there is a direct dictum against fighting.  The body is the physiological basis of a woman’s mind, so any attack on the body is in reality an attack on the woman herself.   She is not separate from her body.  If she hates her body, she hates herself; if she loves her body, she loves her self.  What great things in the world were ever accomplished with hate?   What about love?

With an evolutionary perspective, a woman loves and respects her body.  This is not just something she can do, but rather something she must.  And something that comes naturally.   After just a little bit of practice, it becomes easy to love something that nourishes her, that provides the basis for her life, that gives her pleasure, and that enables her to do all of the wonderful feats and have all of the breathtaking experiences of her life.   Isn’t the body an amazing thing?  Isn’t it a powerful organism worthy of love?  Full of wisdom?  Deserving of trust?   Bodies are amazing, and when they are properly nourished their ability to provide a powerful basis for a lived and amazing human life grows exponentially.

With an evolutionary perspective, a woman is free.  She is free from the dictums of the modern world, free from silly norms, free from hate.   She is free from chronic exercise, free from paying money to food factories and food design chemists, free from counting calories, free from the toxins and bullshit in which so much of the modern world swims.  She is free of self-loathing.  She is free of what society wants her to be.  She is instead exactly what she wants to be.  She is free to be who she is, and to be so fiercely.

With an evolutionary perspective, a woman feels good.  This is a fact!  Sometimes women undertake a paleo diet, or at least some form of it, and find that their effort does not work.  I get that.  But the whole point of an evolutionary perspective is to feel one’s way around food and lifestyle until she finds what fits and works best.   The paleo diet is a template, and it provides a toxin-free, hormone-nourishing springboard off of which women can spring.  From here, women find individually what works best for them.  Their blood sugar levels stabilize, their estrogen dominance diminishes, their energy goes through the roof, their libido skyrockets… whatever they need, they can find it with natural methods and an evolutionary perspective.  For women with health problems, it can take a while.  It can take some troubleshooting.  That’s what people like me exist for.    But it’s out there.  Women who love their bodies and treat them well feel damn good.

With an evolutionary perspective, a woman looks amazing and real.  Overweight women naturally lose weight with an evolutionary perspective.  Period.  Easy.  Done.   Eliminating modern toxins from the diet enables a woman to balance her hormone levels and to let her natural mechanisms for weight modulation come into play.  Women with hormonal acne see their cysts fade and turn into scars.  Women who are weighed down by the pains and fatigue of modern diseases straighten their backs, and rise.   But: Nothing in the world will turn everyone into a supermodel.  That’s not the point.   The goal is not to be supermodels.  It is not to be 00s.  The goal is, in fact, the opposite.  Instead, the goal is to throw off the shackles of female expectations.  It is to be fierce and to be confident and to be healthy exactly as nature intended.  It is to be natural, to listen to one’s body above all other things, to be healthy, to be unapologetic, and to be fierce and hot and all of this, again, not because a woman is meeting social expectations of female physicality–whatever those might be for a particular woman–but rather because in natural womanhood there are serious health and serious pride.   The fact that a paleo diet turns a woman into a natural, glowing, fertile, energized machine is a byproduct.  It’s important, because it demonstrates that the woman is achieving greater health, but it’s only truly powerful in this way in that it shows a woman just how beautiful she is in her own unique, natural body.

With an evolutionary perspective, chins come up.  Look.  It’s amazing, being a natural woman.  It’s the healthiest thing a woman can do.  How can that not be empowering?  How can that not inspire?  How can the world not be in awe of someone who owns what she is, and who uses that to her advantage?    An evolutionary perspective demands that a woman not apologize for who and what she is.  It demands that she embrace and love her body, and she does so, proudly.   It demands that she walk with pride in her power and in her womanhood.  With an evolutionary perspective, a woman’s confidence, life, and joy multiply without end.

With an evolutionary perspective, a woman is fierce.  Being empowered, and learning to not apologize for who and what she is, a woman is enabled to pursue her life and her happiness with vigor.  There is a very serious power in being a natural woman.  With a natural diet, a woman has the fuel to burn brightly.  Working in concert with her body, a woman knows how much she is capable of, and what she can achieve.  Being healthy and nourished and totally self-assured, a woman can walk into any room and be a boss.  Norms won’t get her down.  Self-loathing won’t get her down.  Social pressures to apologize for who she is won’t get her down.  Instead, she will own her desires, and can pursue them with all the ferocity and joy inherent in being healthfully alive.

With an evolutionary perspective, things aren’t perfect.  A paleo diet is not a miracle cure.   I advocate paleo diets, but they will never make someone a super human. Instead, it is about moving forward one day at a time, and about doing everything possible to be alive.  This means eating well, and it also means living freely, and it means each individual chooses what is best for her.  It means moving forward with love and with positivity, and facing an imperfect world and a self– a self perfect in its imperfections–with all the power and wisdom garnered from natural womanhood.


The Healthiest, Happiest, Easiest Weight Loss in the World

The Healthiest, Happiest, Easiest Weight Loss in the World

In the short series The Physiology of Women’s Weight Loss, I highlighted the most important factors that make a woman’s weight loss unique to a man’s.  In Part I, I discussed estrogen.  In Part II, I discussed the mechanisms by which female bodies preserve fat stores.

(And if that wasn’t enough, I went ahead and wrote a book on women’s weight loss, available here.)

I have also discussed why the modern notion of eating less and exercising more fails women time and time again.

How, then, should women move forward?

I believe that what women need is an Evolution Revolution.   What women need is to radically embrace the bodies and genes with which they were born, rather than fight them.


The healthiest, happiest, easiest way to lose weight is to adopt an evolutionary perspective.

In the modern world, a woman often goes to war with her body.  She starves it to lose fat; she fights it to resist hunger; she drives it to exercise more.  In the end, she fails.  The body is almost inevitably more powerful than she.

With an evolutionary perspective, however, a woman does not work against but instead works with her body.  Adopting an evolutionary perspective means that there is no dichotomy between a woman and her body.  It means that they  listen to and influence each other, and work towards greater health in a mutually beneficial, loving relationship.

This is what an evolutionary perspective does:

1) It shows a woman what her body was programmed to handle, and what it was not. 

For example, a woman’s body was programmed to consume natural, whole foods.

The foods that nourish a woman are animal products, vegetables, fruits, and all things found in the wild.  They are extraordinarily nutrient dense, and regular consumption of these products provides all of the fuel and substrates necessary for a woman’s body to perform optimally.

If the foods a woman is eating have been in a factory, chances are good something has been done to them that makes their chemical composition too foreign for bodies to handle.  Preservatives serve as cancer instigators.  Sugar kills insulin metabolism.   Soy acts as an estrogen and throws off hormone balance. Omega-6 vegetable oils inflame immune systems.  Wheat proteins tear holes in intestines.

I wrote more about natural, whole foods in Sexy by Nature.

Her body was programmed for relaxation.

The modern world is full of stressors that never existed in evolutionary history.  People may have chased lions back then, but they did not fret for years on end about whether or not they’d be able to make their mortgage payments.  In order for a woman to function optimally, in order for a woman to be truly fertile, and in order for a woman to be happy and to be alive, she must learn to relax.  She must prioritize her mental health.  She must see the trappings of the modern world for what they are, and, to the extent that she is able, rise above them.

Her body was programmed for sunlight.

Her body was programmed for activity.

Her body was programmed for laughter.

Her body was programmed for eating when it is hungry, and for stopping when it is full.

2) With knowledge of what her body really needs, a woman heals her body.

Aligning modern bodies with what their genes expect of them enables them to become the fit, beautiful, energized machines they are built to be.   With the proper fuel, a woman’s body functions are restored, and her hormones are re-balanced.  Her metabolism becomes sensitive and powerful again, and she witnesses profound change as her body becomes simultaneously natural and hot. 

3) With health comes beauty, energy, empowerment, and life.

The restoration of proper body function enables a woman to accomplish feats she had previously been too hampered to do.  This is made even more amazing by the fact that these feats can be easy.  Sometimes, when we are diseased, we don’t really understand how hampered we are.  For example, we may be fatigued, but not really know it.  Once that barrier is removed, however, body functions ramp up and provide a base off of which anything–physical, mental, aesthetic, active, entrepreneurial, artistic, anything–is possible.

So what does this have to do with healthy, happy, easy weight loss?

Because it is healthy, happy, easy weight loss.  An evolutionary perspective  and diet enable a woman to heal her body.  Once her body is healed, her normal hormonal functions are restored, and she is no longer battling her body in order to lose weight.  She is no longer slaving over elliptical machines in order to cut calories and be in painful, starving energy deficits.  Instead, her estrogen levels are normalizing and her insulin system is becoming sensitive, and her leptin levels are signallng more powerfully to her brain.  In this way, she loses weight and appetite without being obssessed about it.

An evolutionary perspective for weight loss is healthy because it optimizes nutrition.  It is healthy because nutrient intake is maximized.  It is healthy because a woman does not starve herself.  And it is healthy because it eliminates toxins from the diet.  In doing so, a woman minimizes her risk for the vast array of diseases of civilization, and she maximizes her immune system’s ability to kick diseases’s ass.

An evolutionary perspective for weight loss is happy for a variety of reasons.  First, a woman does not starve herself.  She eats freely and easily because she knows the food is going to be metabolized properly by her nourished body.  Second, paleo foods optimize the nutrients necessary for the physiological basis of mental health.   Third, this perspective assures a woman that she is doing something right and natural and beautiful.   With that belief, a the weight of self-harm is lifted off of the woman’s shoulders, and a great feeling of peace, well-being, love, and pride replaces it.  Fourth, the weight loss is easy, and it is effective, and also it clears up acne, or makes hair less oily…. all of these things mean that a woman looks great.  Looking great and feeling great are two things that can send someone’s happiness through the roof.

And finally, an evolutionary perspective is empowering.  No, it is not always simple.  Yes, some people still struggle with damage that has already been done to their bodies.  But women can always be making progress.  And being natural means that a woman takes pride in her femininity.  A woman loves her body.  A woman respects the wisdom and life-giving properties of her body, and she enters into a joyous, grateful relationship with her physicality.  A woman’s body enables her to live life and to kick ass every single day, and for that reason, an evolutionary perspective is a beautiful, life-affirming, happy thing.

An evolutionary perspective for weight loss is easy because weight loss necessarily follows from healing and the restoration of proper metabolic functioning.  An evolutionary perspective does not involve caloric restirction.  It does not involve counting grams or macronutrients or micronutrients (unless someone is trying to troubleshoot a particular issue, with which I can help them do at length).   It does not involve cardio exercise, not necessarily, nor any kind of stress, period.  With love and peace, and without worry about restriction or modern waffling about what’s right and what’s wrong, a woman corrects whatever damage has been done to her body and loses weight effortlessly.  I know that that word–effortless–is bandied about weight loss literature so much that it seems to have lost its meaning.  But it hasn’t.  Weight loss is so simple, and so easy.  Toxins make people overweight.  Whole foods make people smooth-running machines.

Evolution kicks ass.  It makes people hot and empowered without hardly trying.  All they have to do is breathe, and listen, and leap.


Since this post, I’ve written two books to support healthy weight loss in women, available here and here.
