Intermittent fasting is good for weight loss — but only if you follow one important rule. Most people follow a fasting rhythm of 16:8 hours.

While no food is consumed during fasting, the body begins to tap into its fat stores. In the long term this should lead to weight loss. Intermittent fasting can also promote health and even delay aging. Some people only eat at certain hours of the day, others only eat on certain days of the week. The current study also confirms the numerous health benefits that fasting has.
