Most dieters only lose water weight because they do not tap into their fat reserve. You store two types of fuel in your body: fat storage and your glycogen (sugar) reserve.
Glycogen is stored sugar, glycogen as a series of glucose molecules or sugar molecules attached together. You have about 1,700 calories. It is used up pretty fast. You have a lot of fat storage. The average person who is not over weight has about 77,000 calories worth of energy in fat.
Your body cannot tap into fat if there are too many carbs or sugar in the system. Your body will always go first for sugar as fuel if it is present.
The hormone that is triggered by stress is cortisol. Cortisol is a hormone that has a function of regulating blood sugar to a certain degree.
If a person has low blood sugar, cortisol is released and helps the body turn protein, fat, or ketones into sugar. This is called gluconeogenesis (Sugar – new – making something or making new sugar)). The body is making sugar out of non-carbohydrate sources. This happens in the liver.
Stress raises cortisol. Cortisol releases sugar, and there is a spike in blood sugar. Insulin kicks in and pushes the blood sugar down (hypoglycemia), causing low blood sugar. Now, the person will get hungry, crave carbs, and snack. When they snack, they’ll raise the blood sugar, and the whole cycle will start over.
For those of us who seriously want the healing from fasting, read on.
Autophagy converts cellular debris into energy that gets used for survival. It is a metabolic process by which your cells disassemble and recycle themselves.
Autophagy gets activated primarily while fasting or exercising. If you’ve depleted the major sources of energy your body uses, then it’s going to have to find that energy through other means. Namely, self-eating and recycling.
