Science, simplified

Everything here is based on peer-reviewed research. No hype, no magic.

How it works

How fasting burns fat

The metabolic switch: from sugar to fat in about 12–16 hours.

How it works

Why visceral fat matters

The fat around your organs is the one that hurts you — and the first to respond.

Your body

Hunger comes in waves

Ghrelin rises at your usual meal times, then falls — whether you eat or not.

Tools that help

Electrolytes: the missing piece

Most fasting headaches, fatigue and dizziness are sodium, not hunger.

Tools that help

Move to fast better

Walking makes fasting easier; lifting keeps the weight you lose from being muscle.

Tools that help

What doesn't break a fast

Water, black coffee, plain tea and salt are your friends.

Your body

Sleep and cravings

Tools that help

What to eat when you eat

Fasting opens the door; food quality decides how far you walk through it.

Tools that help

How to break a fast

The way you end a fast decides how you feel afterwards.

Tools that help

Mindset

Plateaus and the scale

The scale lies daily. Your waist tells the truth weekly.

Fasting works for women — but start gentler and listen to your cycle.
