Intermittent Fasting 101 — The Ultimate Beginner's Guide


Intermittent fasting limits eating time daily, weekly, or monthly. By limiting eating time, the body has time to digest food, store nutrients, and recover before the next meal. This improves health and encourages healthier eating.


You may want to try intermittent fasting to improve your health. It can help you have more control over when and how you eat during the day or week.

The 16:8 Method

Most individuals intermittent fast this way since it can be tailored to their lifestyle. Fast for 16 hours and eat for the remaining 8 hours—the timing is up to you. 

The 5-2 diet

Fasting becomes a weekly meal plan on the 5-2 diet. For five days, you eat a normal, unrestricted, healthy balanced diet. On two non-consecutive days, you eat 500-600 calories.

The "Eat-Stop-Eat" method involves fasting for 24 hours, maybe many times a week. Many do this by eating dinner and then not eating again until the next day's dinner.
