The grapefruit diet is based on the notion that grapefruit has fat-burning properties. It cuts out sugars, a lot of carbohydrates and a significant amount of calories. To follow this diet, it must be done for 12 days. If a person wants to do it for longer, he must take a two-day break between cycles.
Learn the history of the diet. Since the 1930s, the grapefruit diet has been a short-term weight loss plan with numerous success stories. The basic idea is that when eaten with protein, grapefruits help shed significant weight. The weight loss is mostly from fluid, though, not fat. It works best for quick weight loss of about 10 lbs. for special events. The Atkins Diet is said to have evolved from the grapefruit diet. Grapefruits have a low amount of calories per serving, along with vitamin C, fiber and a low glycemic index.
