Intermittent fasting (IF) can be defined as fasting for less than 2 days. While there are a variety of fasting methods within the category of IF, they are all based on eating patterns that alternate between intervals of eating and fasting. One popular IF routine is the 5:2 Diet, which entails fasting during specific days of the week. For this approach, individuals either eliminate or severely restrict their calories for two (non-consecutive) days of the week and then resume their normal diet for the other five days.
Periodic fasting (PF) is fasting for more than two days, usually anywhere from three to seven consecutive days. Due to its extended duration, PF goes beyond providing weight loss and fat reduction to promote biological fasting and a process known as autophagy, the clean-up of aging and worn-out intracellular components. These cellular cleansing, renewing and rejuvenating effects can only be attained through a prolonged fast like the 5-day ProLon FMD.
