I love intermittent fasting. There are many ways to do it, but I do the eating for a 4-6 hour period daily. My body had started to do this naturally. My eating window is from 9 AM to 3 PM. This has taught my body to switch from burning sugar to buning fat. This lifestyle change is not a diet. It is a pattern of eating that allows my body to “rest” from having to continually be digesting food.
From James Clear, who has been intermittent fasting for over a year, “How Does Intemittent Fasting Work?“:
“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.
Because we don’t enter the fasted state until 12 hours after our last meal, it’s rare that our bodies are in this fat burning state. This is one of the reasons why many people who start intermittent fasting will lose fat without changing what they eat, how much they eat, or how often they exercise. Fasting puts your body in a fat burning state that you rarely make it to during a normal eating schedule.”

From Scientific American, David Stipp writes:” “How Intermittent Fasting Might help You Live a Longer and Healthier Life“. An excerpt fom this article:
“The idea that periodic fasting may offer some of the same health benefits as continuous calorie restriction—and allows for some feasting while slimming down—has convinced an increasing number of people to try it, says Steve Mount, a University of Maryland genetics professor who has moderated a Yahoo discussion group on intermittent fasting for more than seven years. Intermittent fasting “isn’t a panacea—it’s always hard to lose weight,” adds Mount, who has fasted three days a week since 2004. “But the theory [that it activates the same signaling pathways in cells as calorie restriction] makes sense.”
