5. What happens to my body when I fast?
According to the NHS choices website, the changes that happen in the body during a fast depend on the length of the continuous fast. The body enters into a fasting state eight hours or so after the last meal, when the gut finishes absorbing nutrients from the food.
In the normal state, body glucose, which is stored in the liver and muscles, is the body’s main source of energy. During a fast, this store of glucose is used up first to provide energy. Later in the fast, once the glucose runs out, fat becomes the next source of energy for the body.
With a prolonged fast of many days or weeks, the body starts breaking down protein in the body (such as muscle) for energy. In a one day fast your body will not start this process.
