Your body will use stored glucose as energy and continue to function as though you’ll be eating again soon. Your body will use stored fats for energy after eight hours without eating. Your body will use stored fat to produce energy throughout the day. When you eat again, the body uses stored glycogen as its primary energy source. Glycogen is a type of carbohydrate that is stored in the muscles and liver.
It is used to fuel your muscles during exercise, and it is also used as a source of energy for your brain and nervous system during sleep. When you sleep, glucose is broken down into glucose-6-phosphate (G6P), which is then used by your liver to produce glucose for the rest of your life.

What happens to your body if you don’t eat for a week?
If you don’t eat for a long period of time, you will use up the sugar in your system. Ketones are an alternative fuel source which your body makes from fat. If you’ve ever been to a decent holiday party, you’ll know that putting on fat doesn’t make you feel any better. Ketosis is a state in which the body uses fat as its primary energy source.
When you’re in a ketogenic state, it’s not uncommon for your blood sugar levels to drop to dangerously low levels. This is because your liver is producing ketone bodies to help you burn fat instead of glucose. Ketones are produced in the liver when you eat fat, but they can also be produced by your muscles and other tissues when they’re deprived of carbohydrates.
In other words, if you don’t have enough carbohydrates to fuel your cells, they’ll turn to fat for fuel instead. The result is that you’ll feel hungry all the time, and you won’t be able to eat as much as you normally would. You’ll also lose the ability to control your appetite, so you may find yourself eating more than you need to in order to satiate your hunger.
