Your diet hasn't changed. Your workouts haven't changed. Yet your waistline seems to be changing anyway. A lot of women notice more fat around the middle in perimenopause and menopause even when their habits stay exactly the same.

What's happening

Often it isn't straightforward weight gain — it's a shift in body composition. You tend to lose some muscle while gaining fat around the abdomen.

Why your shape changes

As estrogen declines, it affects fat storage, muscle maintenance, insulin sensitivity and how efficiently your metabolism runs. Your body starts favouring the midsection over the hips and thighs. Reduced muscle, poor sleep, higher stress, lower activity and a naturally slowing metabolism all add to it.

What helps

Prioritise protein — it helps you hold on to muscle
Strength train — building muscle supports your metabolism
Manage stress — high cortisol encourages fat around the middle
Improve sleep — poor sleep is linked to weight gain and insulin resistance

When to talk to a doctor

Consider speaking to a healthcare professional if you experience significant or unexplained changes in your weight or body composition, particularly if they happen suddenly or alongside other new symptoms.
