how does it work?

the main reason people try intermittent fasting is to lose fat.

Intermittent fasting is not a diet, it’s a pattern of eating. It’s a way of scheduling your meals so that you get the most out of them. Intermittent fasting doesn’t change what you eat, it changes when you eat.

Why is it worthwhile to change when you’re eating?

Well, most notably, it’s a great way to get lean without going on a crazy diet or cutting your calories down to nothing. intermittent fasting is a good way to keep muscle mass on while getting lean.

To understand how intermittent fasting leads to fat loss we first need to understand the difference between the fed state and the fasted state.

Your body is in the fed state when it is digesting and absorbing food. Typically, the fed state starts when you begin eating and lasts for three to five hours as your body digests and absorbs the food you just ate. When you are in the fed state, it’s very hard for your body to burn fat because your insulin levels are high.

After that timespan, your body goes into what is known as the post–absorptive state, which is just a fancy way of saying that your body isn’t processing a meal. The post–absorptive state lasts until 8 to 12 hours after your last meal, which is when you enter the fasted state. It is much easier for you body to burn fat in the fasted state because your insulin levels are low.

When you’re in the fasted state your body can burn fat that has been inaccessible during the fed state.
