Ana Boot Camp [ABC] Diet

ABC is a restricted calorie diet that lasts for 50 days. The diet is based on the concept of calorie shifting, a dieting theory born from the idea that when you reduce your food intake suddenly, your body shifts into "starvation mode," an evolutionary defense mechanism in which your body's metabolism becomes more efficient in order to cope with an expected shortage of food. By varying the number of calories each day you presumably trick the body into not realizing that it is being confronted with a shortage of food, thus preventing starvation mode.


The ABC Diet works because of the extreme calorie restriction, causing rapid weight loss. Many dieters report losing over 20lbs on the ABC Diet if the diet is followed correctly. Those who do not complete all 50 days lose less weight.
