Intermittent Fasting 101: Understanding the Basics
The concept of intermittent fasting has gained significant traction in recent years, captivating the interest of health enthusiasts and researchers alike. As an eating pattern that alternates between periods of fasting and eating, it offers a unique approach to weight management and overall well-being.
What is Intermittent Fasting?
Intermittent fasting (IF) is not about what you eat, but rather when you eat. It involves cycling between periods of eating and fasting, effectively alternating between energy intake and consumption. This approach has been embraced for its simplicity and potential health benefits.

- 5:2 Diet: Normal eating for 5 days and restricting calorie intake to 500-600 calories for 2 days.
- Eat-Stop-Eat: Fasting for 24 hours once or twice a week.
- Alternate Day Fasting: Alternating between eating normally and fasting every other day.
