Fasting is a form of dieting. Intermittent fasting is the most popular type. Intermittent fasting involves eating very little for a short period of time, often 1-2 days per week. Normal eating takes place during the rest of the week.

Intermittent fasting is most commonly used for obesity. It is also used for other conditions, but there is no good scientific evidence to support these other uses.

Fasting and intermittent fasting reduce the amount of energy (calories) that a person eats over time. This may lead to weight loss and other health benefits.

Intermittent fasting is POSSIBLY SAFE short-term as long as a small amount of energy is consumed daily. It has been practiced for up to 12 months with no serious side effects. The safety of intermittent fasting when used longer than 12 months is unclear. Complete fasting might also be safe when done short-term under medical supervision. But complete fasting is LIKELY UNSAFE when done for a prolonged period.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if fasting is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid fasting.
