One Meal A Day (OMAD) is more than just a diet. It’s a metabolic reset that shifts your body into a completely different operating mode.
The First 12 Hours: Glycogen Depletion
Your body first uses up blood glucose, then taps into glycogen stores in the liver and muscles. After about 12 hours, these reserves are exhausted.
12-18 Hours: Ketosis Begins
Now it gets interesting. Your body switches to fat burning and produces ketone bodies. These serve as an alternative energy source for your brain and often increase mental clarity.
18-24 Hours: Autophagy Activated
The holy grail of fasting: autophagy. Your cells begin recycling damaged components. This cellular cleanup process is linked to longevity and disease prevention.
How to Do OMAD Right:
- Start slowly (16:8 → 20:4 → OMAD)
- Don’t forget electrolytes (sodium, potassium, magnesium)
- Your one meal should be nutrient-dense
- Listen to your body — not every day needs to be OMAD
