People that fall below the minimum amount of calories usually are at risk of gaining every pound back that they have worked so hard to lose. There are also other risks that are involved with being on the diet, and these risks include having a low blood sugar, and low energy levels. People often can experience dizziness if their blood sugar gets too low. Another risk of the diet is that the diet allows people to lose more water than fat deposits, and when the diet is finished, the body does keep saving calories and storing fat. As the body keeps storing fat, people are at risk of gaining weight back this way also.
Depression, fatigue, and paranoia, are other risks that people often experience while on the diet. The theory surrounding this diet consists of it being based on calorie shifting, a dieting theory that was born from an idea that when people reduce their food intake suddenly, their bodies shift into “starvation mode,” a defense mechanism which allows the body’s metabolism to becomes more efficient, in order that it may cope with expected shortages of food. By people varying how many calories they consume each day, they presume that they do trick the body into not realizing it has been confronted with a shortage of food, and this helps to prevent a starvation mode.
