The 16/8 method involves fasting every day for about 16 hours and restricting your daily eating window to approximately 8 hours. Within the eating window, you can fit in two, three, or more meals.

Dr. Naiman suggested that “the sweet spot for intermittent fasting” occurs between 18 and 24 hours of fasting since this is the time period that sees the greatest drop in insulin and increase in lipolysis — the breakdown of fat.
Is it safe to fast for more than 3 days?

Does intermittent fasting increase insulin levels?
It shows that even small increases in insulin, within the normal range, virtually abolish lipolysis (the breakdown of fat). This is where intermittent fasting comes in, as one of its effects is to lower insulin levels and thus increase lipolysis. The question is: how long do you need to fast before insulin comes down? Eating causes insulin to rise.
