People may try this diet to control their food intake and lose weight. Some research suggests that the average female can limit their daily caloric intake to 1,500 calories or less to drop 1 pound per week. The average male may consume up to 2,000 calories a day to lose the same amount of weight.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite.
