Why fasting before your period backfires

Good morning friends,

For years, I thought fasting was the ultimate tool for everyone. Then I saw a close friend struggling. She was moody, exhausted, and her PMS was worse than ever.

Turns out, fasting wasn’t helping - it was making things worse.

Here’s why
Most fasting studies are done on men. Women’s biology is different.

Early in your cycle, fasting works beautifully:
• Keeps energy stable
• Reduces cravings
• Balances blood sugar

But the week before your period, your body needs glucose. Skipping meals spikes cortisol, which:
• Fuels fatigue and mood swings
• Makes PMS worse
• Throws estrogen and progesterone off balance

A better approach
Think of this week as fuelling, not restricting:
• Complex carbs like sweet potatoes or quinoa keep hormones steady
• Nutrient-dense foods like eggs and greens support balance
• Gentle walks, sunlight, and lower stress make a huge difference

It’s like giving your body a steady fuel tank instead of running it on empty.

The truth? Fasting works - but only when you time it with your cycle.
