Increases growth hormone secretion, which is vital for growth, metabolism, weight loss and muscle strength

Human growth hormone (HGH) is a protein hormone that affects a number of body processes. According to studies, this important hormone is involved in growth, metabolism, weight loss, and muscular strength.

Fasting has been shown in several studies to increase HGH levels naturally. Fasting for 24 hours significantly increased HGH levels in 11 healthy people, according to one research. Another small research of 9 men found that fasting for two days increased HGH production by five times. Fasting may also help maintain consistent blood sugar and insulin levels throughout the day, which may help to optimize HGH levels since some research shows that maintaining high insulin levels can lower HGH levels.
