Intermittent Fasting (IF) Meaning
Intermittent fasting (IF) is eating for a specific period of the day and then fasting for the rest of the day.
Intermittent fasting allows drinks in most of the plans. So it suggests that individuals can drink during the fasting period herbal teas, water, and coffee just if it doesn’t contain any calories like sugar or cream.
Instead of having a list of foods to allow and foods to avoid in your plan, intermittent fasting focuses mainly on how long you can eat during the day.
We can better describe intermittent fasting not as a diet but as an eating pattern.
If you decide to follow intermittent fasting, then you are free to pick one of the following ways;
- Daily fasting for a 16-hour and eating freely for the rest of 8 hours.
- Fasting for 24 hours (2 days), twice a week.

Fasting decreases body insulin resistance, which makes it easy for the body to decrease insulin levels. Lower insulin levels the body to store more fats.
