A very important reason some people fast is for weight loss, and fasting is one of the most efficient methods for achieving it.

With our daily energy expenditure ranging between 1,500 and 3,000 kcal, during fasting, we draw all of this energy from our fat reserves.

We are literally burning fat, and can lose 200 to 300 grams of fat per day through fasting. When combined with water weight, we can lose between 500 to 1,000 grams of weight daily.
