What Is Intermittent Fasting?
Intermittent fasting is a way of eating that alternates between periods of fasting and eating. It is based on the concept that humans were designed to eat for short periods of time followed by hours (and sometimes days) of fasting.
How Do You Do Intermittent Fasting?
In intermittent fasting, there are generally no food or calorie restrictions, but there are restrictions on WHEN to eat. For example, eating may be restricted to an 8-hour window during the day, with 16 hours of fasting in between.
Some popular methods of intermittent fasting include:
- 16/8 daily regimen: of 8 hours of eating followed by 16 hours of fasting
- 5/2 method: eat only 500-600 calories for 2 non-consecutive days, and 5 days of normal eating per week
- “Eat-Stop-Eat” method: two 24-hour fasts per week on non-consecutive days
It can take the body two to four weeks to acclimate to intermittent fasting.
It is generally not advised to go for longer periods longer than 24 hours without eating because it might be dangerous.
What Foods Can You Eat While Intermittent Fasting?
In intermittent fasting, there are generally no food or caloric restrictions, only restrictions on when to eat. However, it is generally recommended to stick to healthy foods such as fruits, vegetables, and whole grains.
During the fasting period, non-caloric beverages such as coffee, tea, and water are permitted.
