What Is Intermittent Fasting?
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It doesn't prescribe which foods to eat, but rather when you should eat them.
Popular Methods
The 16:8 Method
Fast for 16 hours and eat within an 8-hour window. For example, eating between noon and 8 PM is one of the most popular approaches.
The 5:2 Diet
Eat normally five days a week, then restrict calories to 500–600 on two non-consecutive days.
Potential Benefits
- May support weight and fat loss
- Can improve insulin sensitivity
- May reduce inflammation markers
- Some research links it to improved brain health
Who Should Be Cautious?
IF is not suitable for everyone. Pregnant or breastfeeding women, people with a history of eating disorders, or those with certain medical conditions should consult a doctor first.
