Short answer
To lose weight during menopause, trials point to the same tools as at any age: eating fewer calories and moving more, kept up for years. In a 5-year trial of women aged 44 to 50, a diet and activity program kept 55% at or below their starting weight, versus 26% without it. For some women, an FDA-approved weight-loss drug is an option to discuss with a prescriber.
Why the middle changes
The "menopause belly" has a measurable basis. In the NIH-funded SWAN study, 380 women had body fat scanned by DXA for a median of 11.8 years. Fat in the belly area grew 1.21% a year before the transition and 5.54% a year during it. Deep visceral fat, around the organs, began rising at the transition, by 6.24% a year.
The authors concluded that the menopause transition is linked to the development of central fat. Waist and hip measurements picked up these changes less well than the scans did.
What the lifestyle trials found
The Women's Healthy Lifestyle Project enrolled 535 women aged 44 to 50 before menopause. The program group got a 5-year diet and activity program; controls were only assessed. After 4.5 years the program group averaged 0.1 kg below their starting weight, while controls gained 2.4 kg. Waist size fell more in the program group too.
The WOMAN trial randomized 508 postmenopausal women, average age 57, to a lifestyle program or health education. At 18 months the lifestyle group had lost 17 lb and 10 cm off the waist. Weight loss was similar whether women stayed on hormone therapy, stopped it, or had not used it.
What a diet change alone did
The Women's Health Initiative put 48,835 postmenopausal women into a trial of a low-fat eating pattern with more vegetables, fruit and grains. It set no weight-loss or calorie goal.
Women in the diet group lost 2.2 kg in the first year. The gap with the control group was 1.9 kg at 1 year and shrank to 0.4 kg by 7.5 years. Weight loss was greatest among women who cut the share of their calories from fat. The trial showed this pattern did not cause weight gain, but on its own it did not produce much loss.
What The Menopause Society says, and where drugs fit
The Menopause Society says weight gain around the transition can be prevented by diet and exercise. For women already overweight, losing as little as 3% can improve cholesterol and lower diabetes risk, and 5% to 10% brings further benefits.
Some women also qualify for medication. The Zepbound label (revised August 2026) approves it, with a reduced-calorie diet and more activity, for adults with obesity, or with overweight plus at least one weight-related condition. Our guide lists every FDA-approved GLP-1 option. Whether one suits you, and at what dose, is your prescriber's call.

Can you target belly fat after menopause?
The trials here cut waist size along with weight, but none tested a belly-only method. SWAN shows belly fat rises during the transition itself.
Does hormone therapy help you lose weight?
It is not FDA-approved for weight loss. Our page on HRT and weight covers the trial data.
How much weight loss is worth it?
The Menopause Society says as little as 3% can bring health gains for women who are overweight, with more benefit at 5% to 10%.
