First of all, keep in mind that every human body is different. Fasting is not for everyone, regardless of the potential benefits. Consult a doctor before fasting, especially if you have diabetes or other health conditions.

Intermittent fasting usually means going 12 to 18 hours without eating, giving your digestive system a short rest. Think of it like going home after work—a needed break, but not as refreshing as a full weekend.

After 48 hours of fasting, your body has depleted its store of glycogen (carbs), starts burning fat, and shifts into ketosis where it creates ketones to be used as fuel.

During ketosis, our cells use a process called autophagy to remove metabolic waste from cells. The body recycles cells that are damaged, weak, or sick; ketosis may even encourage the creation of new white blood cells.

Fasting also has been shown to increase insulin sensitivity, aid in weight loss, reduce inflammation, and even promote mental clarity.

Studies show that it can take 20-48 hours for the body to shift into fat-burning ketosis mode. A 48-hour fast gives your digestive system a nice, cleansing rest and is just enough time for the body to start enjoying the benefits of ketosis.

A 72-hour fast continues the benefits of the 48-hour fast. Think of it as giving your digestive system an extra long weekend while you enjoy the ketogenic state for one more day.
