How do perimenopause and menopause affect weight?

Written by the Progyny Editorial Team. Reviewed by the Progyny Clinical Team — July 2026.

Many women notice weight gain that starts before obvious signs of perimenopause.* Weight gain may continue through the menopause transition, and it can happen even when you lead an active lifestyle and focus on healthy eating.

(*We’ll use the term peri/menopause in this article to refer to perimenopause and menopause together. We use “women” to acknowledge anyone who goes through peri/menopause.)

Weight fluctuation is often natural and there are a range of healthy body types. For some people, however, weight gain during this time may be frustrating or raise health concerns. Managing weight in midlife can help you stay on a path to healthy aging and may boost energy and mood. Let’s talk more about this, keeping in mind that everyone is different.

What causes weight gain during midlife?

For many of us, midlife weight gain happens because our metabolism slows. One factor is that beginning around age 30, we start to lose muscle – and muscle burns more calories than fat.

Weight gain may also happen because when estrogen declines during perimenopause, our bodies don’t handle sugars as well as they once did.

Our lifestyle also affects our weight:

• Midlife can be a time of stress. Stress influences our nutrition, ability to exercise, quality of sleep, and energy to make healthy changes.
• Poor sleep is linked with weight gain. There are many reasons we may not sleep well (including peri/menopause itself).
• We may not always eat nutritious, balanced meals, and our physical activity level might be less than it used to be.

Of course, family history and genetics play a role in our body type and how our bodies change. Health conditions and medicines may lead to weight changes, as well.

Where does peri/menopause fit in?

Peri/menopause isn’t usually the main driver of weight gain, but it may be a factor.

Hormone changes from menopause may affect where we store fat. It often shifts from our bottoms and thighs to our lower belly (abdomen). This type of abdominal fat may raise health risks.

In addition, peri/menopause may cause symptoms that contribute to weight gain. For example, anxiety and night sweats can disturb sleep and add to stress, making it hard to manage weight.

Does menopause hormone therapy (MHT) help?

MHT doesn’t directly affect weight, and it’s not prescribed for weight loss. However, it may help improve disrupted sleep. MHT may also help reduce fat storage in the belly, although more research is needed.

Not everyone can take MHT. If it’s not right for you, there are non-hormonal medicines and strategies to help manage symptoms affecting sleep.

Strategies and support for a healthy weight

Weight management is about finding the path that works for you, not anyone else. (It’s not about what anyone else thinks, either.)

All women’s bodies change over our lifetime, and that is OK and natural. Work with your healthcare provider to track your health and feel good about yourself. And if you want to make small changes, think about what matters most to you. How does a healthy weight connect with that? Identifying this motivation is essential.

Take care of YOU first

Taking care of your overall well-being is an important part of managing weight. Are you sleeping well and practicing self-care? That can often be a good place to start. Allow yourself time for the things that ground you. Ideas include:

• Relaxation techniques like deep breathing or meditation
• Social connection in a group or volunteer setting
• Nights out with your partner or a friend
• Time alone with your thoughts or a good book
• Doing a hobby you love

Healthy eating in midlife

• Continue balanced eating. Emphasize lean protein, fruits, vegetables, dairy, healthy fats, and whole grains. Protein is more important as we age since it helps preserve muscle. (Calculate your protein needs here.)
• Consume fewer calories in your 40s and 50s. Your daily calorie needs go down as metabolism slows. One direct way to do this is to limit empty calories from sugar, processed foods, and alcohol.
• Ask for support. A registered dietitian can optimize your nutrition and personalize strategies for you. And look for support at home so you can plan, prepare, and eat healthy together.

Physical activity that’s right for you

• Do what you enjoy. Aim to get your heart pumping 30 minutes, 5 days a week. You can do this in smaller chunks that add up. The best types of activity: the ones you enjoy! A friend, class, or trainer can all help you get motivated.
• Focus on strength. Strengthening helps you maintain muscle, manage weight, and preserve bone health. It makes daily activities easier, too. Try working up to at least 2 days of strength training a week.

Work together with your provider

Your provider can provide personalized guidance and referrals if needed. They can also determine if medicine (such as GLP-1s) may support you. A menopause provider has specialized expertise for this phase of life.

Your Progyny Care Advocate can help you find in-network nutritionists and menopause specialists. We can also provide education, coaching, and support as you make lifestyle changes.
