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

Okay, so picture this.
You’ve been using a map to get somewhere you really want to go.
You follow it carefully.
You do exactly what it says.
Sometimes it feels you’re definitely heading in the right direction.
But you never quite arrive.
Eventually you end up right back where you started, wondering what you did wrong.
Here’s the thing. The map was wrong.
It wasn’t because you couldn’t follow directions.
It wasn’t because you didn’t try hard enough to read the map.
It wasn’t because you took a wrong turn somewhere along the way.
The map was wrong because it was built for the wrong destination.
And that “map”?
It’s the dieting advice most women have been given for decades.
Restriction.
Willpower.
Eating less.
Suffering more.
These approaches were never designed to help you build a body you feel good in and habits you can actually live with. They were designed to produce short-term results that felt convincing enough to keep you coming back.
And perimenopause?
Perimenopause is often the moment your body finally exposes that the 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 a full 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!)
During this time estrogen begins fluctuating, and those hormonal shifts affect far more than your cycle.
They influence things like:
hunger and cravings
blood sugar regulation
sleep quality
fat storage patterns
mood and anxiety
muscle maintenance
overall energy
In other words, many of the systems that quietly helped regulate weight earlier in life start shifting at the same time.
Which explains why so many women suddenly feel like the rules changed overnight.
Because biologically speaking, they kinda did.
My own “wait, what is happening to me?” moment
For me, it wasn’t just one thing.
It was a combination of brain fog, fatigue, memory issues, mood swings, irritability, anxiety and depression. They didn't show up all at once. At first, it was subtle...a little more forgetfulness here, a bit of fatigue there. But over time, those small changes starting stacking up and then as soon as I started menopause, it felt like everything hit me at once.
And what I started to notice was this:
The more tired and overwhelmed I felt, the stronger my cravings became.
Not cravings for chicken and broccoli(lol. wouldn't that be awesome?!).
Cravings for quick energy, which meant...
Sugar.
Chips.
Anything that felt like it would give me a boost.
And even though I was still working out and trying to eat well, I could see it happening:
I was eating a little more.
Craving more.
And slowly re-gaining some weight.
Not a dramatic amount.
But enough to notice. Enough to feel like something had shifted.
And the frustrating part?
I wasn’t doing anything “wrong.”
I was just tired.
So instead of doubling down and trying to be stricter, I started asking:
What actually needs support here?
Was it my sleep?
Was it my stress?
Was it how I was eating throughout the day?
Because the more I focused on improving my energy(and my blood sugar spikes) — the more my cravings started to calm down.
And once my energy became more stable, everything felt easier to manage.
Not perfect.
But manageable.
I stopped gaining weight and was able to lose what I had gained without restriction.
And honestly? I see this all the time with my clients too.
They’re not sitting there thinking, “You know what I feel like doing today? Self-sabotaging.”
They’re tired. They’re overwhelmed. Their body is asking for energy — and it goes straight to the quickest source it knows.
What’s actually happening in your body
Hormones change where fat is stored
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.
Research consistently shows this shift is strongly influenced by hormonal changes.
Not simply eating more.
Not suddenly becoming less disciplined.
Just biology doing its thing.
Blood sugar becomes more reactive
Declining estrogen can affect insulin sensitivity, which means blood sugar can swing more dramatically.
And when blood sugar swings, you’re more likely to experience:
stronger cravings
energy crashes
those 3pm moments where chips suddenly start sounding like a completely reasonable food group.
They’re not. But at 3pm cravings make you lose all sense of reality and you might strongly disagree. Been there/done that...had to stop buying chips for a while!
Once I started paying closer attention to blood sugar — eating vegetables first, then protein and fat, and carbs last(and never eating sugar on an empty stomach) — my brain fog improved and my energy came back.
Not magic, even though it felt like it, let me tall ya!
Just stability.
Stress hits harder
Midlife often comes with a lot of responsibility.
Work.
Kids.
Aging parents.
And about forty-seven things living rent-free in your mental to-do list.
Add hormonal shifts and disrupted sleep, and cortisol becomes more reactive.
And cortisol loves storing fat around the midsection.
So if your life sometimes feels overwhelming, that’s not weakness.
That’s just Tuesday in midlife.
Muscle becomes more important than ever
After about age 40, muscle mass naturally declines unless we actively maintain it.
Muscle plays a big role in metabolism, blood sugar regulation, and long-term health.
Which is why strength training becomes so valuable in midlife.
Why trying harder often makes things worse
When weight loss gets harder, most women are told to do some version of this:
Eat less.
Exercise more.
Be stricter.
But that often creates a cycle that looks like this:
strict plan → short-term results → exhaustion → rebound → restart
That cycle doesn’t happen because you lack discipline.
It happens because most diets rely on restriction and rigid rules that simply aren’t sustainable long-term.
A crash diet is like cleaning your house by shoving everything into a closet before guests arrive.
The house looks amazing.
Until someone opens the wrong door and an avalanche of stuff falls out.
The mess was never gone.
You just hid it temporarily.
Perimenopause is often the moment your body stops tolerating that cycle.
What actually works (spoiler: it’s not suffering)
Sleep first
Sleep influences hunger, cravings, mood, energy, and cortisol.
Your sleep environment matters.
The temperature matters.
Your bedtime routine matters.
Not glamorous advice.
But glamorous advice rarely works.
And yes, breaking the habit of TV or scrolling social right before bed is extremely hard to break. If I did it(mostly - I'm not perfect!), you can do it too!
Daily movement and nutrition
For short-term weight loss, daily habits matter more than heroic workouts. Again, I'm talking short-term, week to week.
Walk more.
Support blood sugar with balanced meals.
Eat in a way that leaves you satisfied(without complete restriction).
None of this is dramatic.
All of it works to help you create the non-negotiable calorie deficit required for fat loss.
A lot of people assume that if they eat “healthy, work out and move more,” weight loss should automatically happen.
But if calories coming in are still higher than calories going out, the body simply won’t lose fat.
That’s not failure.
That’s physiology.
Small consistent habits help make that “good enough” calorie deficit sustainable without feeling like punishment.
Strength training
Strength training is essential for midlife women.
Not because it produces instant weight loss — it won’t.
But because it builds muscle, and muscle supports metabolism long-term.
Two to three sessions per week is plenty to start.
And listen to your body.
Some days you have a full workout in you.
Some days ten minutes is enough.
Both count.
Stress management
Stress management isn’t optional.
Strength training helps.
Walking helps.
Nature helps.
Personally, I recommend dancing in the forest occasionally.
Highly therapeutic.
And if someone sees you?
Oh well. Let them.
I do.
Your nervous system needs support just as much as your muscles need movement!
Midlife Woman to Midlife Woman
You are not lazy.
You are not broken.
And you are definitely not the only woman standing in her kitchen wondering why the old rules suddenly stopped working.
You’re navigating one of the biggest biological transitions of your life while still managing work, family, responsibilities, and everything else.
Of course it feels harder.
But harder doesn’t mean hopeless.
It just means the strategy needs to change.
And if you feel like you’re doing some of the right things but still not seeing results, that’s often a sign that something specific is 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 which one is yours. Most women who take my quiz discover one pattern they never noticed before.
Designed for midlife women who are done guessing. It takes less than five minutes — and it might change the way you see yourself.
Already taken the quiz and ready for the next step?
