What is Intermittent Fasting?

The science behind Intermittent Fasting:

When we consume food, the enzymes in our gut break it down which converts into molecules in the bloodstream.

Carbohydrates easily get converted into sugar which our cells use for energy. If we don’t use that energy it gets stored in our fat cells.

Sugar can’t enter the cell without the help of insulin. Insulin brings sugar to the fat cells and lets the sugar stored in the fat cells.

As we undergo fasting our insulin level drops so our fat cells release stored sugar to be utilized as energy. So we lose weight if we let our insulin level go down.

Intermittent fasting helps keep our insulin level down long enough to burn off fat.

When we fast our body starts removing toxic materials from the cells, helping detox the body.

Several other molecular changes occur which help longevity and protection against diseases.

Level of Human Growth Hormone may increase which helps in fat reduction and muscle building.

Note: Intermittent fasting helps bring down the insulin level so that our body can burn the stored fat. Other cellular changes occur during intermittent fasting which helps in detoxing and longevity of the body.
