Why do women gain weight around menopause?
Weight gain around menopause is common, but research doesn't show a sudden drop in metabolism at that age. The main drivers are gradual muscle loss, moving less, poorer sleep and hormone changes that shift fat towards the waist. The good news: daily movement matters more than age. For a woman of 70 kg (154 lb), going from 45 to 55 lowers her TDEE by about 60 calories a day; walking 9,000 steps instead of 4,000 adds about 130.
Age vs steps
| Age | 4,000 steps | 6,000 steps | 9,000 steps |
|---|---|---|---|
| 45 | 1,750 | 1,800 | 1,880 |
| 50 | 1,720 | 1,770 | 1,850 |
| 55 | 1,690 | 1,740 | 1,820 |
| 60 | 1,660 | 1,710 | 1,790 |
What changes around menopause
- Muscle: without strength training, muscle declines faster in midlife, which lowers resting burn and strength.
- Where fat goes: falling oestrogen shifts more fat to the abdomen, even if the scale barely moves.
- Sleep and hot flushes: poor sleep increases appetite and makes it harder to stay active.
- Activity: many women move less in their late 40s and 50s, often without noticing; see NEAT.

What helps
- Strength training 2–3 times a week: the most effective way to keep muscle and resting burn. See lifting weights.
- Protein at 1.6–2.2 g per kg of a healthy weight, spread over meals; see how much protein you need.
- Daily steps: the biggest everyday lever for calories.
- Recalculate your maintenance with your current weight, steps and workouts, and adjust gently.
- Sleep and alcohol: both affect appetite and energy more than people expect.
Losing weight during or after menopause
The same rules apply: a moderate deficit of about 0.5% of your weight a week, never below 1,200 calories, with protein and strength training to protect muscle. Use the calorie deficit calculator, and see how many calories a woman should eat. For symptoms such as hot flushes or sleep problems, talk to your doctor about the options.
