There are several ways of fasting, the most popular methods being *intermittent fasting and prolonged fasting*. This article briefly explains what happens during the first hours when we stop eating.

Breaking Down Sugar

Complex sugars are broken down into more simple sugars (also known as monosaccharides), like glucose and fructose.

Glucose is the general metabolic fuel that can be metabolized by any cell and about 25% of total body glucose consumption occurs in the brain. Fructose and other kinds of nutrients can only be metabolized in the liver, where they are transformed into either glucose (stored as glycogen in the liver) or into fatty acids stored in adipose tissue ( fats located beneath the skin, around internal organs, in the breast tissue…etc)

The first few hours of fasting are normal since your body is going through its regular process of breaking down complex sugars and storing glucose.

Ketosis

Depending on blood sugar levels, in around 6 hours your body reaches the ketosis stage, a metabolic
state which your energy levels are supported by ketone bodies. Ketone bodies are a result of the
breakdown of fats and the body uses these molecules when glucose is in shorter supply than normal.

*The Keto diet* is a diet where you put your body in a state of ketosis, making your body burn fats for energy instead of sugars, a very effective way to lose weight.

Conclusion

Whether you plan on ridding your body from harmful toxins, giving your digestive system a break or simply losing weight, you might want to consider fasting to help you achieve these goals.
