Why you crave sugar before your period (and what actually helps)

If the week before your period comes with a sudden urge to eat everything in the cupboard, you're not imagining it — and you're not failing at self-control.

The hormone story

After ovulation, progesterone rises and estrogen dips. That shift can affect serotonin and blood-sugar regulation, which is part of why cravings (especially for carbs and sugar) tend to spike in the luteal phase.

What actually helps

Steady protein and fiber across the day, not skipping meals, and getting enough sleep tend to blunt the swings more than willpower does. Gentle movement and managing caffeine late in the day can help too.

The honest caveat

Most “cycle-syncing” diet rules online are vibes, not evidence. The basics — eat regularly, sleep, move — are what hold up. nura labels what's solid science versus what's just popular.
