How Your Hormones Cause Weight Gain in Menopause

Cortisol And Weight Gain

The first thing we need to look at is the relationship between cortisol and weight. Unfortunately, high cortisol and weight gain go hand in hand. What’s more, cortisol typically rises in menopause. (1)

You see, cortisol is produced by your adrenal glands, mostly in response to stressors in the body. And when your adrenal glands sense that your hormone levels are changing due to menopause, that is a signal of stress for them. So they start dumping out cortisol in response.

Cortisol also plays a role in how your body metabolizes food and plays a role in helping you get to sleep at night and wake up in the morning. (2) That means that when your cortisol levels go high, your sleep can be affected, which in turn can contribute to weight gain. Then there are the night sweats and random bouts of insomnia that interrupt your sleep during menopause, too. It’s a recipe for gaining weight.

It’s also worth mentioning that many women in their menopausal years find that they are under extra stress at work, with aging parents, and children that might still need quite a bit of parenting. This all causes an increase in stress, and therefore cortisol production.

You’ve also got to remember that when your adrenals are feeling stressed out, they have to choose cortisol production over sex hormone production. That means your hormone levels take a nosedive even faster than they would if your adrenals could provide a little bit of backup support.

Basically, it’s a negative feedback loop…one that leaves you feeling very tired and with extra pounds accumulating on your midsection.

What You Can Do About Menopause Weight Gain

So, what can you actually do? There are two important places to start.

Let’s go over both.

Whether we like it or not, in menopause, cortisol typically goes higher. And when that happens...your body thinks it needs to hold onto weight around your central organs to protect itself. (3) High cortisol also contributes to insulin resistance, (4) which we’ll talk some more in a moment.

Which means that if you want to support healthy cortisol levels, you've got to take care of your adrenals. They're the glands that produce cortisol.

How do you do that?

The simplest place to start is adding adaptogens like maca to your daily routine. Adaptogens help your body adapt to everyday stress. My go-to is Mighty Maca Plus.*

One of the most important things you can do to help reduce your blood sugar and insulin resistance is to eat plenty of vegetables and healthy fats.

I outline exactly how to eat to deal with insulin resistance in my book, The Hormone Fix. I also have dozens of resources on my website that can help you learn how to eat in my signature Keto-Green® style, which is how I recommend eating in menopause to support your metabolism.

Ideally, you want to keep your simple carbs low, your healthy vegetable fats high, and your protein moderate. This combination helps support healthy blood sugar and insulin response, and supports your hormones from every angle.

For an easy way to have a meal with the *perfect* Keto-Green® macros, try my Keto-Green® protein shake*. 

Ultimately, supporting your body through menopause weight changes comes down to two things

1. Keep your adrenals supported and calm, so your body can maintain healthy cortisol levels.
2. Focus on eating Keto-Green® to support a healthy insulin response. 

And girlfriend, don’t feel guilty prioritizing yourself! It’s important to take time for those oxytocin moments, reduce your stress, and sleep as much as you need to (most women need about 7-9 hours per night).

You are so much more than your weight. And I honestly believe that you are beautiful and worthy no matter what size jeans you wear! But the reality is that weight gain around the middle can lead to some serious health conditions like diabetes and heart disease. And I definitely don't want that for you.

Always remember that you have so much power to change your health!

Frequently asked questions

Why do women gain weight in menopause?

Menopause weight gain is largely hormonal. As estrogen and progesterone decline, cortisol tends to rise and insulin sensitivity drops. Together, these shifts make your body more likely to store fat, especially around your belly. Natural muscle loss with age slows your metabolism too, so the same habits can lead to different results.

What hormones cause belly fat in menopause?

Cortisol and insulin are the two biggest drivers. Cortisol, your stress hormone, signals your body to hold weight around your midsection. Insulin resistance means more of what you eat gets stored as fat instead of used for energy. Declining estrogen also shifts where fat is stored, moving it from your hips and thighs to your abdomen.

Why am I gaining weight in menopause if I'm eating the same and exercising?

Because your hormones changed, not your willpower. Higher cortisol, lower insulin sensitivity, and gradual muscle loss mean your body burns and stores energy differently than it did in your 30s. That's why cutting calories often stops working in midlife. Supporting your hormones and building muscle tends to matter more than eating less.

When does menopause weight gain start?

For many women it begins in perimenopause, often years before the final period, and can continue into postmenopause. It often levels off about two years after your last period. If your waistline started shifting in your early to mid 40s, hormones are likely part of the picture.

How can I support healthy cortisol levels in menopause?

Start with the basics that calm your stress response. Protect 7 to 9 hours of sleep, move your body daily, and say no more often. Build in moments of connection and joy, which boost oxytocin, the hormone that naturally counterbalances cortisol. Adaptogens like maca may also help your body adapt to everyday stress.

What is the best diet for menopause weight gain?

I recommend a Keto-Green way of eating, which is low in simple carbs, high in healthy plant fats, moderate in protein, and rich in alkaline vegetables. This combination helps support steady blood sugar and a healthier insulin response. Pair it with resistance training a few times a week to protect the muscle that keeps your metabolism strong.
