Fasting for a week:
- Causes significant changes in protein levels across various organs.
- May have health benefits beyond weight loss, but only after 3 days.
- Switches energy source from glucose to fat after 2-3 days.
- Average weight loss of 5.7 kg (fat and muscle), with most fat loss sustained after 3 days of eating.
Implications:
- Provides insights into the molecular basis of fasting's health effects.
- Paves the way for developing alternative treatments based on fasting benefits.
- Confirms historical use of fasting for specific health conditions.
No no, they are saying that you’ll lose a bunch of water weight. As far as I know you generally regain that quite easily once you start eating again.
Personally I subscribe to the idea of calories in < calories out. Sustainable weight loss requires good habits and a healthy relationship with food.
