While it’s not technically fasting, some doctors have reported intermittent fasting benefits by allowing such easy-to-digest food as whole fruit during the fasting window. Modifications like these can still give your digestive and metabolic system a needed rest. For example, “Fit for Life” was a popular weight loss book that suggested eating only fruit after supper and before lunch.
There are different types of intermittent fasting, but the most common involves only eating within a certain window of time each day. For example, you might only eat between 12pm and 6pm each day, giving you a 6-hour “feeding” window when you eat all of your calories for the day. That means you’ll be fasting for 18 hours in between. Your intermittent fasting ratio would then be 18/6.
Both the keto diet and intermittent fasting trigger something referred to as autophagy. The latter is simply the technical term for a natural bodily function called “self-eating.” Although at first this may sound a bit frightening, autophagy is merely your body’s normal detoxification process, during which it eliminates contaminants and replaces them with newly formed, healthy cells.
Each of these plans is designed to get your body used to being in a fasted state for prolonged periods of time, but how each one will work with your particular lifestyle is something that only you can figure out. As you get into intermittent fasting, give these methods a try and see what ones seem like the right fit. And, if you want some good fasting tips, don’t hesitate to reach out to intermittent fasting forums online; a little community support can go a long way towards helping you get into a routine that works.
When you eat a meal, your body spends a few hours processing that food, burning what it can from what you just consumed. Because it has all of this readily-available, easy to burn energy (thanks to the food you ate), your body will choose to use that as energy rather than the fat you have stored. This is especially true if you just consumed carbohydrates/sugar, as your body prefers to burn sugar as energy before any other source.
