Grapefruit Diet

Grape fruit diet has few selected vegetables, small amounts of protein, and grape fruits. This diet works not because of any special enzymes in grapefruit. Grapefruit can help you lose weight simply because the mass-to-energy ratio, that is, the high weight to calorie ratio, makes you full before you get too many calories.The diet lasts for 3 weeks. On a typical day, the calorie intake is restricted to less than 800 calories. This is a severe calorie restricted diet. It is incredibly monotonous and not very healthy.

At the time, nutrition experts dismissed it as another fad diet, explaining that the 'fat-burning' properties of grapefruit were, in fact, a myth and any weight loss that occurred was due to the extremely low and potentially dangerous calorie intake.

The researchers believe grapefruit contains unique plant compounds that reduce insulin levels, which in turn promotes weight loss. This plan is great for people who love grapefruit. Grapefruit has no fat, is low in calories and sodium, and is packed with vitamin C. The pink grapefruit is a rich source for beta-carotene. The plan produces quick weight loss, primarily due to loss of body water. There is no need to count calories as in some other plans.

There is absolutely no scientific proof that grapefruit contains fat-burning enzymes. This plan is low in protein, fiber, and several important vitamins and minerals. Any diet that relies so much on a single food is too restrictive. This diet does not work in all cases.
