Amanda Hamilton reveals how you can shape up for summer and improve your well-being with intermittent fasting. 'Eat, Fast, Slim' contains a choice of diet plans which allow you to tailor the diet to your lifestyle. You can choose Plan A, a daily fast of 16 hours, working up from one fast per week. Or choose Plan B, a full day fast, twice a week, during which you'll eat one evening meal. Plan C enhances the fasts with juicing and other techniques.
