Fasting diets are less of a diet, where certain foods are recommended and others are eliminated, and more of a plan where you eat within a certain time frame of the day and this may lead to weight loss. There are several types of fasting diets, with the most popular probably being the 16/8 Intermittent Fasting diet where you eat for 16 hours of the day and fast for 8 hours, for instance eating between the hours of 11am – 7pm then fasting from 7pm till the next morning at 11am.
