Perimenopause Weight Gain: 3 Myths Women Are Tired of Hearing

One of These Is False. Can You Spot It?

Quick quiz.

One of these statements is false. The other two are true. See if you can pick out the lie.

1. Eating too little for too long can slow your metabolism and stall weight loss.

2. Intense exercise can backfire for women dealing with chronic stress.

3. Weight gain during perimenopause is unavoidable, no matter what you do.

Take a moment before you scroll.

The answer is #3.

Weight gain in perimenopause is not inevitable. Hormonal shifts are real, but inevitability is a story we’ve been told, and it’s one I push back on with my clients all the time.

But the two true ones matter just as much. So let’s go through all three.

#1. Eating too little will stall your progress

This one I see constantly. A woman comes to me eating 1,200 calories, working out five days a week, and the scale won’t move. She assumes she needs to eat less.

The body doesn’t work that way. Chronic under-eating signals scarcity, and the body responds by slowing down. Thyroid function dips, cortisol rises, and muscle gets broken down for fuel. Your metabolism gets very efficient at hanging onto whatever it gets.

Eating more of the right foods in the right way is usually the fix. I know how unintuitive that sounds when you’ve spent years being told the opposite.

#2. Intense exercise can backfire when you’re already stressed

If your nervous system is already running hot from work, poor sleep, caregiving, or just being a woman in the world right now, hard workouts on top of all that can push you over the edge.

Cortisol stays high, and your sleep gets worse. The body holds onto weight because it reads constant exertion as another threat to manage.

This is why I sometimes have clients swap a few HIIT sessions for walking, strength training, or yoga, and they finally start seeing results. Because their body finally gets a chance to settle.

#3. Perimenopause changes things, but it doesn’t make you powerless

Yes, estrogen drops. Yes, cortisol gets more reactive. Yes, sleep gets harder, recovery slows down, and the body holds weight differently, especially around the middle.

Here’s what I’ve seen, though. The women who struggle most through this transition aren’t struggling because of hormones alone. Sleep has been off for years, blood sugar has been swinging, and digestion is a mess. The hormonal shift didn’t create the problem, but made it impossible to ignore.

Which, in a weird way, is good news. Because those other things? They’re addressable.

What actually works

The women I see making real progress through this season aren’t doing anything extreme. They’re doing the opposite.

They’re eating enough and stabilizing blood sugar with protein and fiber. They are treating sleep like it matters, lifting weights to hold onto muscle and addressing the digestion stuff that’s been quietly off for years.

None of it is sexy. But it works.

Catherine, one of my clients, said it best: “I’m feeling the best I’ve ever felt. I’ve lost almost 15 pounds and I’m no longer plagued with a bad attitude toward food.”

That second part is what I care about most. Real change isn’t just what the scale says. It’s how you feel in your own skin, and how much mental space food takes up in your life.

If you’re tired of fighting your body, I’d love to talk. We can figure out what yours is actually asking for, not what some generic plan says it needs.
