Why Belly Fat Is Harder to Lose During Perimenopause and Menopause
Many women reach their 40s, 50s and beyond and notice something frustrating: their body begins to change even though their lifestyle hasn't changed very much. Weight starts to settle around the abdomen. The waist becomes thicker. Clothes fit differently. And the strategies that once worked, eating a little less, exercising more or simply dropping carbs for a few weeks, don't seem to make much difference anymore.
For some women, this happens despite eating predominantly whole foods, exercising regularly and doing many of the things they have been told they "should" be doing. It can be incredibly frustrating. But increasing abdominal fat through perimenopause and menopause isn't always as simple as eating too much or exercising too little. Hormonal changes, blood sugar and insulin regulation, declining muscle mass, thyroid function, sleep, chronic stress, previous illness or injury and the state of the nervous system can all influence how the body manages and stores energy. And usually, there isn't just one factor involved.
The hormonal landscape is changing
Perimenopause isn't simply a gradual decline in estrogen. Hormones can fluctuate considerably during this stage. Estrogen may be relatively high at some times and low at others, while progesterone commonly begins to decline as ovulation becomes less consistent. Eventually, after menopause, ovarian production of both estrogen and progesterone is considerably lower than during our reproductive years. However, estrogen physiology doesn't simply switch off after menopause. Estrogens continue to be produced in other tissues, including through the conversion of other hormones in body fat. The liver and gut are also involved in metabolising, processing and eliminating estrogen and its metabolites. This is one reason the commonly used term "estrogen dominance" can sometimes oversimplify what is actually a much more complicated picture. What matters isn't simply whether estrogen is "high" or "low". Hormone production, fluctuations, metabolism, the relationship between different hormones and the individual woman's overall health all contribute to how she experiences this transition. And a single hormone measurement cannot necessarily describe that entire picture.
Why fat starts accumulating around the middle
One of the most noticeable changes around menopause is often not simply an increase in weight, but a change in where fat is stored. Before menopause, estrogen tends to favour fat storage around the hips and thighs. As the hormonal environment changes, women become more likely to accumulate fat around the abdomen. At the same time, ageing can bring changes in muscle mass, insulin sensitivity, activity levels, sleep and energy expenditure. The result can be a body that responds very differently to exactly the same diet and exercise routine that worked ten years earlier. Your physiology has changed.
Blood sugar can be changing well before you have diabetes
Blood sugar regulation is another important part of this picture. Insulin helps move glucose from the bloodstream into our cells, where it can be used or stored for energy. When cells become less responsive to insulin, the body may compensate by producing more of it. For a period of time, that compensation can help keep blood glucose within the normal range. This means there can be a stage where metabolic health is beginning to change even though a routine glucose result hasn't crossed the threshold for diabetes. This doesn't mean that a normal blood glucose result is meaningless or that everyone needs extensive testing. It means that blood glucose is one piece of a much larger metabolic picture. Waist circumference, blood pressure, cholesterol levels, muscle mass, activity, family history and changes over time can all provide useful information.
My blood tests are normal, but I know something has changed
This is something I hear frequently from women.
They've been to their doctor. They've had blood tests. Nothing concerning has been identified. And that's reassuring. But they still know their body has changed. Their waist is increasing. Their energy isn't what it was. They may be more tired, more wired, sleeping differently, experiencing digestive changes or finding it increasingly difficult to maintain their previous weight. Sometimes their body simply doesn't respond the way it once did. A result sitting within a laboratory reference range is valuable information, but it doesn't mean we should ignore changes occurring in the body. Many metabolic and hormonal changes develop gradually. The body is also remarkably good at compensating. That creates an important space between "everything looks okay" and established disease. And that space is where prevention matters.
Cortisol, chronic stress and abdominal fat
Stress is another piece of the metabolic picture. Cortisol is an essential hormone. We need it to wake up, regulate energy availability, respond to challenges and function normally. The issue isn't that cortisol is "bad". It is that prolonged activation of our stress-response systems can influence sleep, appetite, glucose regulation, blood pressure and metabolic health. But there is another aspect of chronic stress that I think is particularly important for women. You may not actually feel stressed.
When being stressed feels normal
Many women tell me: "I'm really not that stressed." But when we explore what their body has been through over the previous five, ten or twenty years, the picture can look very different. They may have raised children while working. Cared for ageing parents. Managed a household and/or business. Lived through relationship or financial stress. Experienced chronic illness. Recovered from a significant infection or injury. Lived with persistent pain. Spent years sleeping poorly. Or simply become accustomed to being responsible for everyone and everything. When your nervous system has operated at a high level of activation for a long time, that level can begin to feel normal. You don't necessarily feel acutely stressed because your baseline has changed. This is one reason I don't find telling women to "just reduce your stress" particularly helpful. Sometimes there isn't much they can remove from their lives. And sometimes learning to genuinely come out of that state takes time.
The nervous system and metabolism aren't separate
We often talk about metabolism, hormones and the nervous system as though they are separate systems. The body doesn't work that way. Our nervous system is continually responding to information about sleep, illness, pain, emotional stress, energy availability and our environment. A history of prolonged illness, significant infection, injury, chronic pain or sustained emotional stress may all contribute to the physiological load the body has been carrying. This doesn't mean nervous-system dysregulation is the cause of every woman's abdominal weight gain. It means that her history matters. If the body has spent years adapting to high demands, adding harder workouts, more food restriction and another long list of things she "should" be doing may not always be the most useful place to start. Sometimes it simply becomes another stressor.
Thyroid function deserves consideration too
The thyroid plays an important role in metabolism, temperature regulation, energy production, bowel function and many other processes. Changes in thyroid function can also produce symptoms that overlap with perimenopause and menopause, including fatigue, weight changes, constipation, temperature changes, changes in mood and alterations in hair and skin. Persistent or unexplained symptoms are therefore worth discussing with your GP rather than assuming everything is menopause. Again, the aim isn't to assume there must be something wrong because losing weight is difficult. It's about looking at the whole picture.
But I'm already eating well and exercising
This can be one of the most frustrating parts. You might already be:
eating predominantly whole foods
prioritising protein and vegetables
limiting highly processed foods
walking regularly
strength training
limiting alcohol
trying to sleep well
doing your best to manage stress
…and your abdominal fat barely changes and while lifestyle remains enormously important, the response to lifestyle interventions isn't identical for every woman. Age, genetics, hormones, muscle mass, insulin sensitivity, sleep, medications, medical conditions, previous illness and stress physiology can all influence the outcome. The answer isn't necessarily to become increasingly restrictive. Sometimes the more useful question is: What is changing in my body?
Belly fat isn't only about appearance
There is an important difference between the fat we can pinch underneath the skin and visceral fat, which accumulates deep within the abdomen around our internal organs. Higher levels of visceral fat are associated with insulin resistance, type 2 diabetes, cardiovascular disease and other metabolic health concerns. This doesn't mean every increase in waist size represents a health problem. But steadily increasing abdominal fat, particularly alongside changes in blood pressure, blood glucose, cholesterol or other metabolic markers, is worth paying attention to. And this is where the conversation about belly fat needs to move away from appearance. The goal isn't simply to become thinner. It is about protecting our health as we move into the next stage of life.
How Chinese medicine looks at this differently
Chinese medicine doesn't look at "belly fat" as an isolated condition. We look at the pattern occurring in the individual woman. How is her digestion? What is her appetite like? How are her bowels? How does she sleep? Is she hot or cold? What happens to her energy throughout the day? How has her menstrual cycle changed? What menopausal symptoms is she experiencing? How does her body respond to stress? Has there been a significant illness, infection or injury? What else has changed?
From a Chinese medicine perspective, digestion, fluid metabolism, circulation, stress responses and the changing balance of Qi, Blood, Yin and Yang may all be relevant depending on the individual. Some women may also have heard of the Chinese Medicine term “Damp”. This describes a traditional pattern associated with the way the body processes and distributes fluids and nourishment, and may be considered when symptoms such as heaviness, sluggishness, bloating, fluid retention or a tendency to gain weight occur together. It is not simply another word for body fat, and whether it is relevant depends on the woman’s overall pattern.
This means two women who both walk into my clinic saying "I can't get rid of this belly" may have very different underlying patterns. And therefore they may need very different approaches.
My approach is progressive
In my own clinical work, I don't generally start by trying to "boost metabolism" or force the body to lose weight. I prefer to work progressively. Where appropriate, this may involve looking first at inflammation and digestive function. From there, we may need to consider the nervous system and ongoing stressors, circulation, and eventually areas where the body may need more support or nourishment. Chinese herbal medicine and acupuncture may form part of this approach alongside appropriate nutrition, movement, strength training, sleep and medical investigation. The aim isn't to force the body into submission. It is to understand what may be getting in the way of healthier function.
Sometimes the first goal isn't weight loss
This can be an important shift. Instead of seeing your abdomen as the problem that needs to be attacked, it can be useful to see it as one piece of information about what is changing in your body. Improving blood sugar regulation. Maintaining and building muscle. Supporting sleep and addressing chronic stress. Investigating thyroid or other medical concerns where appropriate. Improving digestive health. Creating genuine periods of recovery for a nervous system that may have been "on" for years. These may all be more meaningful starting points than simply eating less. Body composition may change gradually as overall health improves, but health remains the primary goal.
Don't wait until something is "wrong"
Perimenopause and menopause are sometimes treated as something women simply need to get through. I see them differently. This stage of life provides an important opportunity to take stock of what has changed. If your waist circumference is steadily increasing, your blood sugar is creeping upward, you're losing strength or muscle, your energy has declined or you simply know your body is functioning differently, you don't necessarily need to wait until those changes become significant enough to receive a diagnosis before paying attention to them. That doesn't mean searching for disease when none exists. It means taking prevention seriously. There is a large and important space between apparently healthy and established disease. For some women, the next step may be speaking with their GP and having appropriate investigations. For others, it may mean changing how they eat, building more muscle, improving sleep or reconsidering how much recovery their body actually gets. And for some women, acupuncture and Chinese herbal medicine may form part of a broader, individualised approach to supporting health through perimenopause, menopause and beyond.
In Chinese medicine, we have always been interested in patterns — the collection of smaller changes that tell us something about how the whole system is functioning. Rather than waiting until one symptom or pathology result becomes significant enough to define the problem, I think there is value in asking:
What is beginning to change, and what might my body need now?
Because stubborn abdominal fat isn't always simply a weight problem. Sometimes it's one of the first visible signs that it's time to look more closely at our metabolic health.
