The Science of Intermittent Fasting: Benefits and Tips

Intermittent Fasting

Intermittent Fasting is not the process of avoiding any particular types of foods, but rather of choosing when to eat. This eating pattern involves having a regular time of eating and then not consuming it for some time. Several methods of intermittent fasting include:

16/8 method: Probably the fastest method is to fast for 16 hours and eat only 8 hours of the day, usually eating the last meal of the day and the first meal the next day.

5:2 method: This requires a normal diet for the first five days of the week and a reduced diet limited to 500-600 calories for only two days of the week and on different days of the week.

Eat-Stop-Eat: Obviously, fast for 24 hours once or twice a week.

Alternate-day fasting: Eat normally for several days, then eat very low-calorie foods for a day or two, or even go without them.

Biological Processes During Fasting

Several major biological processes start during fasting:

1. Insulin sensitivity: It reduces insulin levels and insulin's ability to store fat, which leads to loss of body fat. The reduction in insulin levels makes it possible to mobilize stored fat to be used as energy resources.

2. Autophagy: Fasting reactivates autophagy which is a process of destruction of damaged cells and replacement with new cells that increases longevity and reduces diseases.

3. Hormone regulation: It has the following effects on hormones; Growth hormone and norepinephrine which are used in muscle growth and fat breakdown are increased by fasting.
