Tag: Intermittent fasting hours

According to Johns Hopkins neuroscientist Mark Mattson, our bodies have evolved to be able to function for many hours without food. While the most popular method involves a 16-hour fast, the time required to be considered intermittent fasting can vary, with some protocols starting at just 12 hours.

According to Dr. Berg, the most popular intermittent fasting schedule is the 16:8 method, which involves fasting for 16 hours and eating during an 8-hour window. This approach is often recommended as a starting point, but Dr. Berg also discusses longer fasting periods for more experienced practitioners.

The one-meal-a-day (OMAD) diet is an extreme form of intermittent fasting that restricts all daily calorie intake to a single, compact eating window. Typically, this translates to a 23-hour daily fast, with all food consumed during the remaining one-hour period.
