If you’re a health-conscious woman in your thirties or forties, there’s a good chance you’ve spent years trying to eat well, especially if you care about maintaining a healthy weight, staying in shape, aging well, and reducing your risk of chronic disease.
Many women in this demographic have experimented with plant-based, Mediterranean, vegetarian, or pescatarian diets, or Whole30. Others have simply tried to follow the advice most of us have heard for decades: eat plenty of vegetables, choose lean proteins, limit fat, watch your sugar, prioritize fiber, and fill your plate with foods that are low in calories but high in micronutrients.
None of this sounds extreme, which is exactly why it can be so hard to recognize when these choices have gradually created a diet that’s much lower in energy than you realize.
This is a pattern I see frequently in health-conscious women, and I’ve lived versions of it myself. A woman may not think of herself as dieting at all. She may be eating big salads, lots of leafy greens and fibrous vegetables, lean meat or fish, beans or soy, and relatively small amounts of starch, fruit, sugar, and fat, because she genuinely believes this is the safest way to protect her health. These meals can be very filling, since fiber and protein are highly satiating, and they may help her stay lean. So there may be few signals telling her something is missing.
But over time, she may notice that her energy isn’t what it used to be, her cravings are harder to make sense of, her hormonal or menstrual health is changing, her digestion is less resilient, or fertility is becoming more complicated.
What she may not realize is that despite eating foods we commonly call healthy, she may not be giving her cells enough of the raw materials they need to produce energy efficiently, and to keep her feeling well long-term, especially as she moves into her perimenopause years.
Signs You Might Be on a Low-Energy Diet
Under-eating doesn’t always look like hunger. Especially on a high-fiber, high-protein diet, it often looks like this:
- Low or unstable energy: afternoon crashes, relying on caffeine, or feeling tired even after a full night’s sleep
- Strong cravings: especially intense cravings for sugar or carbs, often in the afternoon or evening
- Feeling cold: cold hands and feet, or feeling chilly when others are comfortable
- Menstrual changes: irregular, lighter, or missing periods, worsening PMS, or more painful cycles
- Disrupted sleep: trouble falling asleep, or waking in the middle of the night feeling wired
- Digestive struggles: constipation, bloating, or sluggish digestion despite eating “all the right things”
- Mood shifts: feeling anxious, irritable, flat, or less resilient to stress
- Hair, skin, and nails: thinning hair, dry skin, or brittle nails
- Low libido
- Fertility challenges: difficulty conceiving, or cycles that suggest you may not be ovulating regularly
- Feeling full but not satisfied: getting hungry again soon after a large, fiber-heavy meal
None of these signs proves you’re undereating on its own, and many have other possible causes. But if several sound familiar and your diet is built mostly around vegetables, lean protein, and “clean” foods, your energy intake is worth a closer look.
Why This Mistake Is So Easy to Make
I think this mistake has become especially easy to make because women are surrounded by frightening information about obesity, diabetes, heart disease, cancer, environmental toxins, aging, and weight gain. At the same time, we’re exposed to celebrity doctors, health influencers, wellness personalities, and constantly changing dietary philosophies promising to help us avoid those outcomes.
And nearly all of these magic-pill diets center on eating more vegetables.
The conversation revolves around what we need to eliminate, restrict, or protect ourselves from. Much less attention goes to energy metabolism, stress physiology, cellular energy production, glucose availability, what nutrient density actually means, where to find fat-soluble vitamins in food, or the consequences of chronically eating less energy than our bodies need.
As a result, a woman can become incredibly knowledgeable about what she should and shouldn’t eat without ever learning one of the most foundational concepts in nutrition: how to meet her own energy needs.
This is where I believe a bioenergetic perspective gives women a much more useful framework. Rather than starting with another list of foods to eliminate, we can start by asking how the body produces energy, what nutrients and substrates that process requires, how quickly an individual woman uses that energy, and whether her current intake actually supports her needs. Once you understand those basics, nutrition becomes much less about following generalized rules and much more about understanding your own physiology.
That knowledge gives you far more agency over how you feed yourself long-term, instead of leaving you dependent on whichever dietary philosophy happens to be popular at the moment (usually one centered on a lot of low-energy, albeit pretty, foods).
How a “Healthy” Diet Can Become a Low-Energy Diet
Part of what makes this pattern hard to recognize is that we’ve learned to judge food mainly by its micronutrient content, calorie density, or association with disease prevention.
We’re told to eat vegetables for vitamins and minerals, fiber for digestive and heart health, lean protein for muscle, and antioxidants to protect against aging and disease. These aren’t meaningless considerations, but they don’t tell the whole story of what food does in our bodies. Food also has to provide energy, and that energy powers essentially every process we’re trying to support in the first place!
Digestible carbohydrates are especially important here, because they provide glucose, which the body uses to produce adenosine triphosphate (ATP), the energy currency used throughout the body.
That doesn’t mean carbohydrates are the only nutrients involved in energy metabolism, or that every woman should eat the same amount of them. It does mean that lumping all vegetables in as “carbs” hides an important difference between fibrous vegetables and foods that provide far more usable carbohydrate. A bowl of leafy greens, broccoli, cucumbers, and green beans technically contains carbohydrate, but it provides far less glucose than fruit, root vegetables, grains, or other starches.
In fact, most of the above-ground vegetables we’re taught to build our diets around are mostly water and fiber, with relatively little usable energy.
This matters most when the bulk of a woman’s diet is both highly satiating and relatively low in energy. Because fiber and protein make us feel so full, she may have little sense that she’s undereating. She can eat an enormous salad with vegetables and lean protein, feel stuffed afterward, and still take in far less energy and usable carbohydrate than she would from a meal with appropriate portions of fruit, starch, fat, protein, and well-cooked vegetables.
If that pattern repeats throughout the day for years, she can end up on a low-calorie or lower-carbohydrate diet without ever choosing to be on one. In research, this state is often called “low energy availability,” and it’s well documented in female athletes, but it’s by no means limited to them.
The problem is that many of the outcomes women want from their diets require adequate energy in the first place: strong metabolic and thyroid function, stable energy, healthy digestion, hormonal resilience, fertility, good sleep, and the ability to stay active and maintain a healthy body composition as we age. The body has to keep allocating energy to all of these processes, and it has to get that energy from food. When energy availability is chronically low compared with what the body needs, it makes sense that the body begins cutting its spending rather than operating as though energy were abundant.
This is often where we start running on stress to make up for the missing energy, which slowly erodes the functions that chronic stress sits upstream of.
Why This Can Work Against the Metabolism We’re Trying to Protect
This is one of the paradoxes I see in women who are deeply committed to their health. They may eat this way specifically to stay lean and protect their metabolism, while asking their body to maintain a high level of energy expenditure with very little incoming energy to work with.
Over time, those two goals work against each other, and metabolism slows down.
In my work, I’m especially interested in how a woman’s food intake interacts with her thyroid patterns, stress physiology, blood sugar regulation, lifestyle demands, nervous system state, and oxidation rate (how quickly her cells burn through their resources). The body doesn’t experience nutrition as an isolated list of ingredients. It experiences food in the context of how much energy is available compared with how much is being demanded.
A woman who exercises often, works long hours, mothers young children, sleeps poorly, carries a heavy emotional load, or lives in a chronic state of physiological stress may need far more energy than someone with a very different life, even when both are following the same generic nutrition advice and eating similar diets.
This is also why cravings can be so confusing. Women are often taught to see cravings, especially for carbs or sugar, as evidence that they lack discipline or need to restrict those foods even more.
But when I see strong cravings in someone eating mostly lean protein, fiber, and low-energy foods, my first question is whether she’s eating enough. I want to know her overall calorie and macronutrient intake, whether she has nutrient deficiencies, what her stress load is, how she’s sleeping, and how much energy she’s spending each day.
These questions matter even more when fertility and hormonal health are involved, because reproduction requires significant biological resources. If a woman wants to support her fertility, conceive naturally, have a healthy pregnancy, and eventually mother without burning out, I don’t think we can separate those goals from whether her body is consistently getting enough energy and nutrition to meet its basic needs.
That’s why I see metabolic health, fertility, and nervous system health as deeply interconnected rather than as separate areas of women’s health.
What I Want Women to Focus On
Before making another major dietary change, I want a woman to gather information about what she’s currently eating, rather than assuming it meets her needs.
One useful starting point is temporarily tracking calories and macronutrients, so we can see what she’s actually eating instead of relying on how full she feels or how healthy her meals seem. Women are often surprised by how different their intake is from what they assumed, and I can relate to this myself! This isn’t about turning food into a permanent math problem or encouraging obsessive tracking. It’s a short-term way to check whether someone who believes she’s eating plenty is actually getting far less energy than she realizes. (If you have a history of disordered eating, tracking may not be right for you, and this is best done with support.)
From there, I look at nutrient status and metabolic patterns in a broader context. Depending on the woman, this may include Hair Tissue Mineral Analysis (HTMA) alongside relevant blood markers like ferritin, copper, and B vitamins, as well as thyroid, adrenal, and blood sugar patterns. No single number explains a woman’s health, and these markers are only useful in the context of her overall patterns. I’m interested in how the information fits together with her symptoms, diet, health history, menstrual and fertility patterns, digestion, sleep, and daily life.
I also want to understand how much energy a woman is spending, not just how much she’s eating. Her workload, exercise habits, caregiving responsibilities, nervous system patterns, emotional stressors, and sleep all shape how her body uses the food she eats. I also use her HTMA patterns and metabolic type to help assess her oxidation rate, meaning how quickly she appears to be using nutrients and energy.
This moves us away from the idea of one universally healthy macronutrient ratio or meal structure and toward a much more individualized question: what does this woman need to nourish the body and the life she actually has?
The one pattern that IS consistent among almost all my clients is that they need more carbohydrate, sometimes substantially more.
What This Looked Like for One of My Clients
One of my clients, whom I’ll call Amy, came to me with significant digestive issues that had been placed under the broad umbrella of IBS, along with low energy, anxiety, and depression.
At the time, I was working with her specifically on nutrition and digestive health. I wasn’t yet trained in C-PTSD or nervous system regulation the way I am now, so I was very aware of the limits of my role in her mental health, and Amy was also working with a psychiatrist on her mental health and medications. My hope was that improving her nutrition and digestion would reduce some of her physiological stress and support her overall well-being, without pretending nutrition alone could explain or treat the complexity of her situation.
When I assessed Amy’s diet and health history, one pattern stood out: how much fiber she was eating compared with how little energy she was actually getting.
She’d repeatedly been told to increase her fiber in response to her digestive symptoms, so she kept adding more vegetables and fiber supplements to fix the problem. She was doing exactly what she believed she was supposed to do, yet her symptoms kept getting worse. She also hadn’t realized that leafy greens and fibrous vegetables don’t provide nearly as much glucose as fruit, root vegetables, grains, and starches. She believed she was eating plenty of carbohydrate because she ate so many vegetables, when in reality her meals were giving her a huge amount of fiber and fullness and very little energy.
So rather than adding another supplement or even more fiber, we changed the balance. We reduced her fibrous vegetables to smaller side portions, and at breakfast she often swapped vegetables for ripe fruit. We built more of her meals around starchy, glucose-supplying carbs, including well-prepared grains, root vegetables, fruit, and small amounts of simple sugars where appropriate for her. Most of her vegetables were cooked to make them easier to digest, while raw carrots and the occasional side salad stayed in her diet.
Her digestive symptoms improved very quickly. That was especially meaningful because she’d spent years trying to solve them by increasing the very thing that seemed to be contributing to the problem.
We also used her HTMA results to look at her mineral patterns and worked on increasing minerals like sodium, potassium, magnesium, and zinc, which play important roles in normal digestion. Amy had been relying on large amounts of fiber for years to stay regular, rather than looking at why regularity was so difficult in the first place. By giving her body more usable energy, which the cells of her gut need to function, and addressing her individual mineral patterns, we were able to support her digestion from a very different angle.
Amy’s mental health remained the most complicated part of her situation, and she continued working with her mental health professionals on her anxiety, depression, and medications. I would never suggest dietary changes can replace psychiatric or trauma-informed care. But the improvements in her digestion, energy, and sleep gave her a stronger physical foundation and brought some relief to her overall well-being, including her mental health.
Her experience is a good example of why I don’t assume that adding more conventionally “healthy” foods will make someone healthier, especially when it hasn’t worked so far. Sometimes we have to ask what those foods are replacing, how much energy the overall diet provides, and whether the strategy actually makes physiological sense for her.
But Aren’t Vegetables Healthy?
A very logical question at this point is: if vegetables aren’t the answer, why do people who eat more of them often seem healthier? And why do so many health experts recommend emphasizing fruits and vegetables while limiting sugar and carbs?
Some of this advice is absolutely reasonable, which is why I think it’s important to bring nuance to this conversation rather than replacing one reductive nutritional philosophy with another. I’m a big fan of vegetables, and an even bigger fan of fruit. I don’t think women should stop eating them. The issue is that women are rarely taught to eat them in the context of their overall energy needs, or taught to think very deeply about why we need food in the first place.
Here’s something I like to point out: nothing in the human body is created for free. Not enzymes, hormones, or neurotransmitters, and not a single function, action, or thought. They ALL require energy from somewhere. If it doesn’t come from our food, the body takes it from our own tissues.
Yes, leafy greens and other vegetables contain valuable micronutrients, and fibrous foods can play useful roles in digestion, satiety, and a healthy diet overall. But micronutrients are only one part of nutrition. The body also needs enough energy to digest, absorb, transport, convert, and use those nutrients in the first place. Glucose is an important fuel for cellular energy production, which is why I want women to understand the difference between eating foods that technically count as carbs and actually eating enough glucose-producing carbs to meet their needs.
We also have to consider how quickly an individual woman uses her energy. If your meals are dominated by salads, fibrous vegetables, and lean protein, and that has unintentionally created a lower-carb, lower-calorie diet, while you also want a robust metabolism and live a life with significant energy demands, your body has to reconcile some serious competing conditions. This is where stress physiology starts shaping how we age and how we feel the longer it goes on.
The question isn’t whether salad is healthy or sugar is unhealthy. It’s whether the total pattern of your diet provides enough energy and nutrients for your physiology, activity, stress load, and oxidation rate.
This kind of conversation is much harder to fit into popular nutrition content, because it requires moving past simple rules about “good” and “bad” foods and understanding some basic physiology. It doesn’t hand us a frightening food group to eliminate or a rigid diet identity to adopt, so it doesn’t spread as easily. It may be less marketable than telling women to cut sugar, build every meal around vegetables, eat the rainbow, or alkalize themselves. But I think it gives women a far more sustainable framework for feeding themselves over a lifetime.
The Problem With How We’ve Been Taught to Think About Healthy Eating
I believe decades of health and diet culture have produced a very reductive understanding of nutrition and female physiology.
We’re taught to think extensively about nutrients, toxins, disease prevention, body weight, blood sugar, and which foods are supposedly harmful, but very few women are ever taught the foundations of energy metabolism or encouraged to ask whether their diets actually meet their energy needs. That leaves health-conscious women especially vulnerable, because the more committed they become to “clean eating,” the easier it is to accidentally remove the foods that would give their bodies the energy they’re asking for.
This doesn’t mean women have to choose between meeting their energy needs and giving up vegetables, fruit, nutrient density, or concern for long-term health, which is strangely how I often see these two approaches framed. It means placing those things within a bigger physiological framework instead of an ideological one.
A side salad can be a wonderful part of a meal, but it isn’t a full meal, and eating one doesn’t make you “good” or virtuous. Well-prepared vegetables provide important nutrients and variety, and fruit provides both micronutrients and useful carbohydrate. But none of these foods needs to become another rigid rule, and eating a large volume of vegetables shouldn’t automatically be equated with nourishing yourself well, or with winning some purity contest.
Women in particular tend to put their eating into a moral framework where it doesn’t belong.
What we really need is to understand why meeting our energy needs matters, then learn to build meals that provide enough energy, protein, carbohydrate, fat, vitamins, and minerals for the woman eating them. That’s ultimately what I want women to gain from bioenergetic principles: enough foundational knowledge to evaluate nutrition advice rather than automatically obeying it because it taps into some unconscious idea of purity, goodness, or health.
When you understand why your body needs energy moment by moment, which foods provide different forms of it, and how your needs change with your physiology and life demands, you become much less dependent on generalized nutrition philosophies, or, honestly, influencer nonsense.
You can still learn from research, practitioners, and health information, but you’ll have a framework for interpreting it, instead of being pulled from one extreme to another or making choices out of desperation to look or feel better. For me, this is about returning agency to women around their own capacity for self-nourishment. Eating well shouldn’t mean spending your life afraid of sugar, fat, carbs, animal foods, weight gain, toxins, or whichever food becomes diet culture’s next target.
Eating well, and caring for ourselves and our families, should mean understanding our bodies well enough to nourish them in a way that supports energy, hormonal health, fertility, metabolism, and long-term well-being, while still leaving room for flexibility and individual differences.
How I Help Women Apply These Ideas
In my coaching work, I don’t simply tell women to eat more carbs or hand them a generic bioenergetic meal plan. First, I want to understand what’s actually happening in their bodies and their lives.
We assess food intake through tracking, look at symptoms and health history, use testing where it’s useful, and examine the bigger context of their metabolic health, lifestyle demands, stressors, and nervous system patterns. From there, I create a thorough protocol with clear steps, so every change is connected to the patterns we’ve identified rather than being another collection of arbitrary health rules.
Implementation matters just as much as the protocol, which is why my coaching clients also get unlimited WhatsApp support between our weekly or biweekly sessions. That support lets us see what happens when the plan meets real life, notice what’s working, adjust what isn’t, answer questions as they come up, and provide accountability while new habits take root.
My goal isn’t to make a woman dependent on me to tell her what to eat forever. She won’t be working with me forever, and who wants that life? I want her to understand the principles well enough to make these decisions herself long-term. Once women understand the foundations of energy metabolism, they approach food very differently. Instead of constantly asking whether a food is good, bad, inflammatory, fattening, toxic, or forbidden, they can ask whether their overall diet is truly nourishing them, and whether it makes sense for their unique physiology and energy demands.
That’s a far more useful question to carry through life’s changing seasons, as energy needs, fertility goals, activity, motherhood, stress, and aging continue to evolve.
If this is an area where you could use help, feel free to reach out and let me know what you’re struggling with. You can book a free chat with me here to see whether one of my coaching containers is a good fit for your health needs.
If you’d prefer a smaller commitment of time and money, you can also book an HTMA consultation, where we’ll look at your oxidation rate, energy patterns, and overall metabolic health through the lens of your cellular mineral status. It’s the only single consultation I offer, and it’s the most comprehensive way to start this work on a smaller budget.
Whatever path is right for you, I hope you walk away from this article with a deeper respect for your body’s energy needs, and for the role you play in your health by meeting them.
