Research conducted around Intermittent Fasting has shown how fasting can be used to safely lose weight, help increase overall health and resistance to disease, but more importantly keep the weight off without going down the route of conventional dieting which can often lead to feelings of deprivation and ultimately feelings of diet failure. Fasting has been used for thousands of years and is one of the oldest therapies in medicine.
