Why You Can’t Lose Weight in Perimenopause (And It’s Not Your Fault)

Picture this.

You’ve been handed the same weight loss map for years.

Eat less. Move more. Be disciplined. Try harder. Start again Monday.

Sometimes it even looks like the map is working. You lose a few pounds and think, “Okay, this time I’ve got it.”

But eventually, you end up right back where you started, wondering what you did wrong.

Here’s the thing.

The map was wrong.

Not because you couldn’t follow directions. Not because you didn’t try hard enough. Not because you lack willpower.

The map was wrong because most dieting advice was never designed to help you build a body you feel good in and habits you can actually live with.

And perimenopause?

Perimenopause is often the moment your body finally exposes that the old map was wrong all along.

First — what even is perimenopause?

Perimenopause is the transition phase leading up to menopause, and it can start anywhere from your late 30s to mid-40s, sometimes up to a decade before your final period.

So if you’re in your early 40s thinking, “That’s not me yet,” it might already be you. Surprise! Sorry. Tiny hormonal confetti cannon.

During this time, estrogen begins fluctuating, and those shifts affect far more than your cycle. They can influence hunger, cravings, blood sugar regulation, sleep, mood, anxiety, energy, muscle maintenance, and where your body stores fat.

Many of the systems that quietly helped regulate your weight earlier in life start shifting at the same time. So if it feels like the rules changed overnight, that’s because biologically speaking, they kind of did.

My own “wait, what is happening to me?” moment

For me, it was brain fog, fatigue, anxiety, cravings, and that strange feeling of not quite recognizing my own energy anymore.

The more tired and overwhelmed I felt, the stronger my cravings became.

My body wasn't whispering, “Joanna, please fetch kale.” Wouldn't that be awesome!? It wanted quick energy: sugar, chips, anything crunchy, salty, or sweet that promised a fast little rescue mission.

Even though I was still working out and trying to eat well, I was eating a little more, craving more, and slowly regaining weight.

I wasn’t doing anything “wrong.” I was tired.

So instead of getting stricter, I started asking better questions.

Is it my sleep? My stress? My meals during the day? My energy? My blood sugar?

The more I focused on supporting my energy instead of controlling my food, the more my cravings calmed down. Once my energy became more stable, everything felt easier to manage.

Not perfect. But manageable.

I see this with my clients all the time. They’re not self-sabotaging. They’re tired, overwhelmed, and their body is asking for energy.

That’s not weakness. That’s biology asking for support.

What’s actually happening in your body

As estrogen fluctuates and gradually declines, fat that once settled more around the hips and thighs becomes more likely to accumulate around the abdomen.

Hello, belly fat. Rude entrance. No invitation.

Declining estrogen can also affect insulin sensitivity, which means blood sugar can swing more dramatically. When blood sugar swings, you’re more likely to experience cravings, energy crashes, brain fog, and those 3 p.m. moments where chips and cookies start sounding like a reasonable food group.

Sadly, they are not;) But at 3 p.m., your brain may present a convincing legal case.

Stress can also hit harder in midlife. Work. Kids. Aging parents. Relationships. Responsibilities. And about forty-seven things living rent-free in your mental to-do list.

Add hormonal shifts and disrupted sleep, and cortisol can become more reactive. And cortisol loves storing fat around the midsection.

So if your life feels overwhelming, that is not a character flaw. That is Tuesday in midlife.

And then there’s muscle.

After about age 30, we naturally start losing muscle unless we actively work to maintain it. By midlife, that loss can affect metabolism, blood sugar regulation, strength, bone health, and long-term independence. 

This is why strength training becomes so valuable in midlife. Not because it gives direct instant weight loss. It usually doesn’t. But because it helps you build the kind of body that supports you for the long run.

Why trying harder often makes things worse

When weight loss gets harder, most women are told some version of this:

Eat less. Exercise more. Be stricter. Try harder.

But that often creates a cycle:

strict plan → short-term results → exhaustion → rebound → restart

That cycle does not happen because you lack discipline. It happens because most diets rely on restriction and rigid rules that are not sustainable long-term.

Perimenopause is often the moment your body stops tolerating that cycle.

What actually works (spoiler: it’s not suffering)

Start with sleep. I know you probably heard this already, but it's time to finally make some changes.

Sleep affects hunger, cravings, mood, energy, and cortisol. When you're exhausted, everything feels harder. Cravings get louder. Workouts feel heavier. Patience disappears.

Then focus on daily movement and nutrition.

Walk more. Eat balanced meals. Include protein. Support blood sugar. Eat in a way that leaves you satisfied.

And yes, fat loss still requires a calorie deficit. Calories coming in need to be lower than calories going out.

That’s not diet culture. That’s physiology.

But the goal is not to create that deficit through misery, restriction, and white-knuckling your way through life. The goal is to build habits that make a modest calorie deficit easier to sustain.

Strength training matters too.

Two to three sessions per week is plenty to start. Some days you may have a full workout in you. Some days, ten minutes is enough. Both count.

Strength training helps preserve muscle, support metabolism, improve blood sugar regulation, protect bone health, and help you feel strong in your body again.

The missing piece: self-compassion and habit-building

This is the part most weight loss advice skips.

You can know that sleep matters, protein matters, strength training matters, and walking helps.

But knowing what to do and actually building those things into your real life are two different beasts.

One is information. The other is identity.

Long-term weight loss is not about being “on plan” or “off plan.”

That thinking keeps women stuck in the all-or-nothing cycle.

Perfect week? Great, you’re “good.”

Messy week? You “blew it,” so you might as well restart Monday or give up completely.

No thank you.

The real goal is to build habits that help you become the kind of person who takes care of herself consistently, even when life gets "lifey".

Because life will get lifey.

There will be birthday parties, stressful weeks, bad sleeps, travel, busy days, hormonal days, overeating at Thanksgiving and dinners that are less “balanced meal” and more “whatever I found while standing in front of the fridge.”

That is not failure. That is being a human woman with a life.

This is where self-compassion matters.

Not the fluffy kind where you say, “It’s fine,” and ignore what happened. Useful self-compassion.

The kind where you say:

What can I learn from this? What do I need next time? Did I let myself get too hungry? Was I tired, stressed, or overwhelmed? What habit would make this easier tomorrow? Why do I feel guilty leaving food on my plate? Why do I go back for seconds when I’m probably not hungry? What old habit from childhood might still be running the show?

That shift changes everything.

Instead of judging yourself, you get curious.

And curiosity is far more useful than shame.

This also means learning to listen to your body again.

Honour your hunger before it becomes an emergency. Because once you get too hungry, logic leaves the building wearing roller skates.

That’s when the “I’ll make a balanced meal” brain turns into “I need crackers immediately and nobody speak to me.”

So build the habit of having simple options ready: Greek yogurt, a boiled egg, veggies and hummus, or a small handful of nuts.

And just as important, practise eating to about 80% full.

Not stuffed. Not uncomfortable. Just satisfied.

This takes practice. It means slowing down enough to notice what your body is telling you.

And yes, weight loss may be slower this way. Good.

The goal is not perfection. The goal is to keep returning to the habits that support you.

That is how you stop dieting and start becoming a healthy person.

Someone who knows how to take care of herself in the middle of actual life.

Midlife Woman to Midlife Woman

You are not lacking discipline or willpower.

You are not broken.

And you are definitely not the only woman standing in her kitchen wondering why the old rules suddenly stopped working.

Of course it feels harder. But harder does not mean hopeless. It means the approach needs to change.

If you feel like you’re doing some of the right things but still not seeing results, something specific may be blocking your progress.

For some women, it’s all-or-nothing thinking. For others, it’s an overloaded nervous system.

For others, it’s the self-criticism spiral that turns one off meal into a three-week detour.

You don’t have to figure it out alone.

The first step is finding out what's the main thing actually getting in your way.
