Many people simply eat too much of the wrong foods and live a sedentary lifestyle which leads to weight gain and eventually obesity. Of course that simple answer doesn't mean that it's simple for people to lose weight. Most diets fail because they are too difficult for people to stick with and/or they make the body go into starvation mode. The Day Off Diet solves both of those problems with it's weekly "day off" which allows the dieter to eat anything they want once a week. This lets the dieter satisfy their cravings while also boosting the metabolism. Unlike other less successful diets, The Day Off Diet doesn't require any calorie counting or carb counting.
