Why Am I Gaining Weight During Perimenopause?

You haven't suddenly started eating completely differently.

You're still doing the things you've always done. Maybe you're even eating less than you used to.

And yet your jeans feel tighter.

Your stomach seems softer. The number on the scales has crept up. Suddenly you're carrying weight around your middle in a way you didn't before.

So you start wondering: Why am I gaining weight when nothing has really changed?

If you're going through perimenopause, hormones may be part of the story.

Why does menopause cause weight gain?

First, let's clear something up.

Perimenopause doesn't mean that every woman will automatically gain weight.

But changes in your body during perimenopause and menopause can make weight management feel different from how it did in your 20s or 30s.

Hormonal changes can affect where your body stores fat, while getting older can also bring changes in muscle mass, activity levels and metabolism.

And then there's everything else happening at the same time.

Poor sleep.

Stress.

Less energy.

Changes in appetite.

Hot flashes waking you up at night.

You can see how it starts to become a bit of a perfect storm.

Why is the weight going to my stomach?

This is something women often notice.

You might not feel like you've gained weight everywhere, but suddenly your waistline seems to be changing.

During and after menopause, body fat distribution can change, with more fat tending to accumulate around the abdomen.

That doesn't mean you've done anything wrong.

Your body is changing.

And unfortunately, doing hundreds of crunches isn't going to specifically burn belly fat either.

There isn't a magic exercise that tells your body, only lose the fat from my stomach please.

But what if I'm eating the same?

This is where it can feel incredibly unfair.

You might be eating the same foods you've always eaten and suddenly finding that your weight is creeping up.

Part of the reason can be that your body's energy needs change as you get older, particularly if you're losing muscle mass and becoming less active.

That doesn't mean your metabolism has suddenly "stopped".

It means your body isn't necessarily working in exactly the same way it did ten or twenty years ago.

And that's why constantly eating less isn't always the answer.

What actually helps?

Think less about punishment and more about supporting your body.

A balanced diet with plenty of protein, vegetables, fruit, whole grains and other nutrient-rich foods can help you get the nutrition you need.

Strength training is particularly useful too.

Building and maintaining muscle becomes increasingly important as we get older, and weight-bearing exercise can also support bone health.

You don't have to spend two hours in the gym.

Walking, resistance exercises, weights, Pilates and other forms of regular movement can all have a place.

The goal isn't to punish yourself for gaining weight.

It's to keep your body strong and healthy while it's changing.

Don't forget about sleep

This one is easy to overlook.

If you're sleeping badly because of night sweats, hot flashes or waking up throughout the night, you're going to feel different the next day.

You're tired.

You're less motivated.

You might crave quick energy.

And exercising when you're exhausted can feel like the last thing you want to do.

That's why looking at weight in isolation doesn't always make sense during perimenopause.

Sleep, stress, food, movement and hormones can all be connected.

You don't need to hate your body

This might be the most important part.

Your body changing doesn't mean you've failed.

You haven't suddenly become lazy or lost your willpower.

You're going through a stage of life that can bring genuine physical changes, and it makes sense that your body might not look or respond exactly as it did at 25.

You can want to lose weight and still be kind to yourself.

You can want to feel stronger without hating your body.

And you can care about your health without spending your life chasing a smaller number on the scales.

If you've noticed unexplained or significant weight changes, or you're concerned about what's happening with your body, it's worth speaking with your doctor. Weight changes can have many causes, and it's important not to assume everything is automatically menopause.
