Menopause Weight Loss: What Works, From Diet to GLP-1s

How much weight do you need to lose to make a difference?

Less than most of us assume. For people with overweight or obesity, the NIDDK says losing 5% to 10% of your starting weight may help improve your health by lowering blood sugar, blood pressure and triglycerides. It adds that losing weight can also improve other problems related to overweight and obesity, such as joint pain and sleep apnea.

In my reading, that range is worth holding onto, because so much menopause weight-loss marketing promises far more. A goal you can reach and keep is worth more than a bigger number you can't.

Can losing weight help hot flashes?

For some women, it may. The Menopause Society's 2023 nonhormone position statement lists weight loss among its recommended treatments for hot flashes, at Levels II–III, meaning the evidence is limited and partly expert opinion. It notes that women with obesity are more likely to report more frequent and severe hot flashes.

It says randomized trials have found that weight loss from behavioral programs is associated with fewer hot flashes, and that the effect may be greater earlier in the transition, in perimenopause and early postmenopause, than later. It's also candid about the limits: the studies are small pilots, nonrandomized trials or analyses of trials designed for something else, and larger trials are needed. Its conclusion: "weight loss may be used to improve VMS for some women."

Our hot flashes guide covers the treatments with stronger evidence, and our weight gain article looks at what's known about weight and night sweats.

Which diet works best for menopause weight loss?

A very large trial in postmenopausal women wasn't even trying to produce weight loss, which makes its result interesting. The Women's Health Initiative Dietary Modification Trial randomized 48,835 postmenopausal women in the US to a program that cut fat and added vegetables, fruit and grains, or to a control group. It set no weight-loss or calorie goals.

Women in the eating program lost an average of 2.2 kg (about 5 pounds) in the first year and stayed lighter than the control group for an average of 7.5 years, although the gap narrowed from 1.9 kg at one year to 0.4 kg by the end. Weight loss was greatest among women in either group who reduced the share of their calories from fat, with a similar but smaller trend for eating more vegetables and fruit.

In my reading, two lessons come out of it. A sustainable eating pattern, without calorie counting, moved weight a little and kept it from creeping up for years. And the effect was modest, which is a useful reality check against any diet sold as the menopause answer. If you prefer a less restrictive pattern, our Mediterranean diet article covers that evidence.

How much exercise does it take to lose weight in midlife?

Possibly more than the minimum. The NIDDK points to the federal physical activity guidelines, which recommend at least 150 minutes a week of moderate-intensity aerobic activity and at least 2 days a week of muscle-strengthening activities. It adds that you may need more than 300 minutes of moderate-intensity activity a week to reach or maintain your weight-loss goal.

Muscle-strengthening is part of the federal recommendation, not an extra. Muscle in midlife is covered in our articles on menopause muscle loss and creatine. If exercise is new to you, our guide to exercise and sleep in menopause covers how activity and sleep affect each other.

Do GLP-1 drugs like semaglutide and tirzepatide work after menopause?

They are on the NIDDK's June 2024 list of six FDA-approved drugs for long-term weight management: orlistat, phentermine-topiramate, naltrexone-bupropion, liraglutide, semaglutide (Wegovy) and tirzepatide (Zepbound). It says a doctor may prescribe one for adults with a BMI of 30 or more, or 27 or more with a weight-related problem such as high blood pressure or type 2 diabetes.

On average, the NIDDK says, adults who take prescription weight-management medicines as part of a lifestyle program lose 3% to 12% more of their starting weight after a year than people in a lifestyle program without medicine, and with some medicines more than half of participants lose 10% or more. It's equally clear that the medicines "don't replace physical activity and healthy eating habits."

Here is one study in postmenopausal women specifically, and it is small. A retrospective study from the Mayo Clinic, published in Menopause in 2024, looked at 106 postmenopausal women treated with semaglutide. The 16 who were also on hormone therapy lost more weight at 12 months than the 90 who weren't, 16% versus 12%, and the gap held after adjusting for other factors. The authors call for larger studies to confirm it.

Are compounded or online GLP-1 drugs safe?

The FDA has published a list of concerns. It says unapproved versions of GLP-1 drugs, including semaglutide and tirzepatide, don't undergo its review for safety, effectiveness and quality before they're marketed. It says compounded drugs should only be used when a patient's needs can't be met by an FDA-approved drug.

It also advises getting a prescription from your doctor and filling it at a state-licensed pharmacy.

The FDA lists warning signs that an online seller may not be legitimate. They include claims that a compounded drug is the same as an approved one, prices that seem too good to be true, medicine that looks different from before or arrives damaged, no screening or prescription by a licensed doctor, and no doctor available for questions afterwards.

• Multi-dose vials: the FDA recommends discarding a vial within 28 days of first use, even if medicine remains, because the risk of contamination rises.
• Warm deliveries: it advises not using any injectable GLP-1 that arrives warm or without enough refrigeration.
• Counterfeits: it is aware of counterfeit Ozempic in the US, which could contain the wrong ingredient, too much, too little or none.
• Newer names: it says retatrutide and cagrilintide cannot be used in compounding under federal law and have not been found safe and effective for any condition.

What happens when you stop a weight-loss medication?

You'll probably regain some weight, the NIDDK says, and building healthy eating habits and more physical activity may help you regain less. It also says that if you don't lose at least 5% of your starting weight after 12 weeks on the full dose, your health care professional will probably advise you to stop and try a different plan.

It says people who have lost enough weight to improve their health, without serious side effects, may be advised to stay on the medicine indefinitely, and that because obesity is a chronic disease, the new eating and activity habits may need to continue for years. In my reading, that's the question to ask at the start, before the first prescription: what's the plan if it works, and what's the plan if it doesn't?

What about berberine, peptides and weight-loss supplements?

Berberine has a small signal, from a review that wasn't about menopause. A 2020 meta-analysis of 12 randomized trials found that berberine reduced body weight by about 2 kg (around 4.5 pounds) on average. Its abstract doesn't describe the trials as studying women in menopause, and 2 kg is modest next to the prescription options above.

Peptides are a different story. The FDA keeps a page on bulk substances used in compounding that may present significant safety risks. Among the peptides it describes are BPC-157 and AOD-9604, whose nominations for compounding were later withdrawn. For both, it says they may pose a risk of immune reactions for certain routes of administration and that it has found no, or only limited, safety information. For AOD-9604, it adds that it has identified serious adverse events that may be associated with it, though causality is not clear.

And the general warnings about supplements apply here too: the FDA doesn't approve them for safety or effectiveness before they're sold. Our guide to menopause supplements covers what the evidence says about the most popular ones, and our blood sugar article covers how blood sugar and sleep interact.

Hi — I'm Ellen. Weight is the menopause topic with the most noise and the least patience. I wanted one page that says what's been tested, what's only being sold, and how modest the honest numbers are.

I'm not a doctor. I'm not an expert — and I'm never going to talk down to you like one. I'm a woman in the middle of perimenopause who got tired of vague answers, started reading the actual research, and writes it down here in plain English, the way I'd explain it to a friend over coffee.
