How Does It Work? Demystifying Intermittent Fasting Methods

Intermittent fasting focuses on when you eat rather than what you eat. Finding the right fasting schedule requires careful consideration of your lifestyle, health goals, and individual preferences.

Here are some popular methods:

16/8 Method: Fast for 16 hours and restrict your eating window to 8 hours each day. This allows for a longer daily fast while still providing a comfortable eating window. 

5:2 Diet: Eat normally for 5 days and restrict your calorie intake to 500-600 calories on 2 non-consecutive days. This method offers flexibility and can be easier to integrate into your lifestyle.

Eat Stop Eat: Fast for a 24-hour period once or twice a week. This approach can be more challenging but may offer potent health benefits.
