Why You’re Craving Carbs at 5pm in Perimenopause (And What Your Body Actually Needs)
There’s a very specific moment many women in perimenopause know intimately.
It’s around 5pm.
You’re standing in the kitchen, tired, overstimulated, mentally done for the day… and suddenly all you can think about is bread, chips, chocolate, wine, or eating “something naughty” straight from the pantry.
And what’s frustrating is this: you may have eaten well all day. You had the smoothie. The salad. The fibre-packed lunch. The protein snack. The collagen in your coffee. The handful of nuts while answering emails…
So why does it suddenly feel impossible to stay on track by late afternoon?
The answer is not lack of willpower.
It’s physiology.
Because one of the biggest shifts that happens during perimenopause is that the body becomes far less resilient to stress, blood sugar swings, poor sleep, under-eating, and nervous system overload. The old habits that once “worked” can suddenly leave women feeling ravenous, shaky, emotional, flat, or completely out of control around food by the end of the day.
Your body is not being dramatic. It’s trying to protect you.
Why 5pm Hits So Hard in Perimenopause
Hormones in midlife are constantly fluctuating - particularly estrogen and progesterone - and these changes impact everything from insulin sensitivity to cortisol levels, appetite regulation, sleep quality, mood, and energy production.
At the same time, many women in their 40s and 50s are also:
under huge mental load
sleeping poorly
skipping meals
over-caffeinating
exercising harder while eating less
running on stress hormones all day
By 5pm, the nervous system often feels depleted.
And when the body senses depletion, it looks for the fastest possible source of energy and comfort: quick carbs, sugar, alcohol, crunchy foods, dopamine hits.
This is why so many women feel “good” all day… then suddenly unravel by dinner time.
One of the Biggest Causes? Not Enough Protein Earlier in the Day
This is one of the most common patterns I see.
Women are unintentionally under-eating protein throughout the day, especially at breakfast and lunch. A piece of toast. A smoothie with barely any protein. A salad without enough substance. Grabbing something quick while working.
Then by late afternoon:
blood sugar crashes
energy drops
cortisol rises
cravings intensify
hunger feels urgent
Protein is incredibly important in perimenopause because it helps stabilise blood sugar, supports muscle mass, improves satiety, and creates much steadier energy across the day.
This is one reason I’m such a big believer in aiming for around 30g of protein per meal in midlife.
Not for dieting.
For stability.
Poor Sleep Makes Cravings Worse
If you’ve slept badly, your body is already operating under stress before the day even begins.
Sleep deprivation impacts hunger hormones significantly. Women often experience:
stronger cravings for sugar and refined carbs
reduced impulse control around food
increased cortisol
more emotional eating
lower energy and motivation
This is why the “I’m fine until 5pm” experience is often even stronger after a rough night’s sleep.
Your body is looking for quick energy because it’s exhausted.
The Nervous System Piece Nobody Talks About
This is the part I think many women need explained properly. Most 5pm cravings are not simply about food. They’re about regulation.
By the end of the day, many women are overstimulated, emotionally depleted, decision-fatigued, and carrying elevated stress hormones from morning until night.
Food - especially highly processed carbs and alcohol - temporarily soothes the nervous system because it creates a dopamine response and gives the body a sense of relief.
That doesn’t mean you’re weak. It means your nervous system needs more support.
I focus so heavily on creating calming 5pm rituals instead of relying on restriction and willpower.
Because women don’t need more self-discipline at 5pm.
They need support.
What Actually Helps
The good news is that these cravings often improve dramatically when the body feels safer, steadier, and properly nourished. Some of the biggest game-changers are surprisingly simple:
Start the day with real protein
Aim for at least 30g at breakfast if possible. This helps stabilise blood sugar and energy much earlier in the day.
Build a “steady plate”
Think:
protein
fibre-rich carbs
healthy fats
colourful plants
This combination keeps women fuller for longer and reduces the dramatic late-afternoon crash.
Eat enough during the day
Many women are accidentally under-eating in an attempt to “be good,” then ending up overeating at night because the body is genuinely hungry.
Take a 10-minute walk after meals
This can help support insulin sensitivity, digestion, blood sugar stability, and energy.
Create a 5pm nervous system ritual
This matters more than people realise.
It could look like:
herbal tea in your favourite mug
magnesium drink
a protein snack before cooking dinner
sitting outside for 10 minutes
a short walk
calming music
a shower before dinner prep
stepping away from screens
Small signals of safety and regulation genuinely help.
You Don’t Need More Willpower
I think many women have spent years believing their cravings mean they’re failing.
But often, the body is simply under-fuelled, overwhelmed, exhausted, or dysregulated.
Perimenopause is not a personal failure.
It’s a physiological transition.
And the solution usually isn’t eating less, punishing yourself harder, or trying to “be good” all day.
It’s supporting the body differently now. With more protein, steadiness, nourishment, more nervous system care.
And honestly?
A little more compassion at 5pm.
