If your clothes are fitting differently around the middle, you are not alone, weight changes during menopause, and especially shifts in where your body stores fat, are a normal part of the hormonal transition. Understanding why these changes happen, and what shapes them, is a more useful starting point than trying to undo them through restriction.
Why fat distribution shifts during menopause
There are many factors at play around the menopause that can contribute to changes in your body shape and weight including changes in hormones, metabolism and lifestyle. Oestrogen helps decide where your body stores fat. As your levels fall towards the end of perimenopause and into menopause, fat can start to settle more around your middle (known as central or visceral fat) than around your hips and thighs.5
Fat that gathers around your middle carries more health risk than fat stored around your hips and thighs. It lines up more closely with heart disease and insulin resistance, the point where your body responds less well to insulin. That is why this particular shift is worth paying attention to, mainly for your long-term health.6
How menopause can affect your metabolic rate
Your metabolic rate is the speed your body burns energy at rest. In midlife, it can slow down. This is thought to be influenced by ageing, activity levels and changes in body composition, including a possible reduction in muscle mass. This loss of muscle is in part due to changes in hormones that happens during perimenopause and menopause.1

This is part of why the approaches that worked at an earlier stage can feel less effective now. The way your body works has shifted, so the same habits can give you different results.
Why severe restriction tends to make things worse
Very low-calorie or crash diets are a hard strategy to sustain through menopause. One big reason is that they can contribute to more muscle loss, which slows your metabolic rate further. That can set up a cycle where the approach you started with makes the underlying issue harder to handle over time. If you are thinking about big changes to how you eat, it is worth speaking to your GP or a registered dietitian first.7
A balanced way of eating, is one that includes a range of foods and enough of the nutrients you need and gives you a steadier foundation for long-term health through this transition rather than short bursts of restriction or leaning on single supplements.8
The nutrition worth focusing on
Because muscle plays a role in your metabolic rate, getting enough protein matters during and after menopause. Protein supports your lean muscle. Good sources include lean meats, fish, eggs, dairy, beans, pulses, and nuts. Spreading protein across your meals, rather than loading it into one sitting, may help your body put it to use more effectively. If you eat plant-based, beans, pulses, tofu, and nuts can carry a good share of your protein.29
Fibre from fruit, vegetables, and wholegrains also earns its place. It supports your digestion and may support your heart health too, and it builds the kind of balanced eating linked with better outcomes through menopause.
