- 16:8 Method: This involves fasting for 16 hours and eating within an 8-hour window. For example, you might skip breakfast and only eat between noon and 8pm.
- 5:2 Diet: This involves eating normally for 5 days of the week and restricting calorie intake to 500-600 calories on the other 2 days.
- Alternate Day Fasting: This involves fasting every other day, with some variations allowing for 500-600 calories on fasting days.

- Reduce insulin levels and improve insulin sensitivity
- Increase human growth hormone (HGH) production
- Boost metabolism and fat burning
- Reduce inflammation and oxidative stress
