This means fasting for 16 hours and eating for 8 hours. The most common fasting or time-restricted eating regimens are as follows: While a 12-hour fast hasn’t been studied in experimental trials, it logically seems like the first place to start with time-restricted eating - stop the after-dinner snacks.

Religious cultures have practiced it for centuries. While the buzz surrounding IF is recent, this practice isn’t new. Many clinicians feel their patients have more success with intermittent fasting when eating low-carb or higher protein diets, but there is currently insufficient evidence that pairing one particular type of diet with IF is superior to another. However, that may not mean people can eat whatever they want during the eating window.

You may be more likely to get better health benefits if you also pay attention to what kinds of foods you eat, but some studies involving IF that did not control what people ate still showed meaningful improvements.
