ASK BOBBIE WEDNESDAY
“Why am I suddenly STARVING before my period?”
Ever have a week where your normal meals are fine…and then suddenly you feel like you could eat everything in the kitchen?
First: you’re not imagining it.
A 2025 systematic review and meta-analysis pooled 15 datasets involving 330 naturally menstruating women ages 18–45.
On average, women consumed about 168 more calories per day during the luteal phase—the phase after ovulation and before the next period—than during the follicular phase. (PubMed)
What might be happening?
Think of your body like an engine whose idle speed gets turned up slightly after ovulation.
Progesterone rises during the luteal phase, body temperature increases slightly, and research suggests resting energy expenditure may rise a little too.
A meta-analysis of 26 studies involving 318 women found a small increase in resting metabolic rate during the luteal phase. (PubMed)
A newer systematic review found increases generally around 30–120 calories per day, or roughly 3–5%, although results weren’t consistent across every study. (PubMed)
So yes—your body may actually be using slightly more energy.
But here’s where we need some nuance.
A newer controlled study published in 2026 followed 18 women and found no significant difference in appetite or food intake between late-follicular and mid-luteal phases. (PubMed)
Translation?
The average pattern exists. That doesn’t mean every woman experiences it every month.
🐐 GOATGETheR TAKE
If your hunger increases before your period, don’t immediately label it:
“I have no discipline.”
Instead ask:
“What is my body telling me?”
Your cycle may be part of the answer.
But so can:
Poor sleep.
Harder training.
Stress.
Eating too little earlier in the day.
Or simply needing more food.
Your menstrual cycle is information—not instructions.
TRY THIS
Next cycle, track your hunger from 1–10 each evening.
If you repeatedly notice hunger increasing before your period, experiment with making your meals more satisfying instead of fighting your appetite all day.
Think:
Protein + fiber-rich carbs + some dietary fat.
For example:
Greek yogurt + fruit + nuts.
Chicken + potatoes + vegetables.
Eggs + whole-grain toast + avocado.
Then watch what happens.
We’re not trying to “beat” hunger.
We’re learning its pattern.
MYTH CHECK
❌ “Your metabolism goes crazy before your period, so you can eat whatever you want.”
No.
The metabolic increase found in research appears relatively small.
But the opposite extreme isn’t accurate either:
❌ “PMS hunger is completely psychological.”
The evidence suggests menstrual-cycle physiology can contribute to changes in energy intake and metabolism.
THE ONE-MINUTE ANSWER
Ever notice you’re hungrier right before your period?
After ovulation, your body’s energy expenditure may increase slightly, and research shows women on average eat more during the luteal phase.
Think of it as your body’s engine idling a little higher—not suddenly burning thousands of extra calories.
Takeaway: Don’t automatically fight the hunger or use your cycle as permission to abandon your nutrition. Track it, fuel yourself well, and learn whether the pattern actually happens in your body.
👇 YOUR TURN
Do you notice yourself getting hungrier before your period?
YES / NO / I NEVER PAID ATTENTION
I chose this question for Wednesday because it hits the sweet spot for GOATGETheR: “Why is this happening to me?” → simple physiology → something a woman can actually test on herself.
The main source is Tucker et al.’s 2025 systematic review/meta-analysis in Nutrition Reviews. Read the PubMed paper The metabolism evidence comes from a 2020 meta-analysis and a newer 2026 systematic review. 2020 resting-metabolism meta-analysis 2026 resting-metabolism systematic review
Evidence confidence: 7/10. I’m reasonably confident that on average energy intake tends to be higher in the luteal phase, but much less confident that any individual woman will experience a predictable increase every cycle. That’s exactly the distinction I want the community learning to recognize.
