The tempting promise of intermittent fasting is that changing mealtimes rather than meals themselves may be more beneficial. Exactly what guidelines apply to less frequent eating?

Both CEOs and celebrities agree that intermittent fasting can aid in weight loss and health improvement. Dietitians advise caution when missing meals, despite positive research suggesting that fasting can hasten our bodies’ natural healing processes and possibly lengthen our lives. Fasters who practice intermittent fasting compress their meals into a narrower window of time during the day by allowing a long interval between their last meal of one day and the first of the next. Many people who fast attempt to eat every eight hours, with a 16-hour minimum between meals.

There may be other reasons to change one’s eating habits besides weight loss, so those who desire to lose weight may not want to try intermittent fasting. The mechanism linked to fasting, known as autophagy, is becoming more popular due to the potential health benefits. It is the procedure by which the body begins recycling the insides of the cell structures.
