The Grapefruit Diet

The Grapefruit Diet started in the 1930s under the name Hollywood Diet. The claim of this diet was that the grapefruit has a special fat-burning enzyme and this enzyme gets activated when the dieter eats half a grapefruit during every meal, in addition to small amounts of other food. There is no viable basis for this belief. Grapefruit is a good substance like many other fruits and vegetables.

It is now established that the grapefruit is an excellent fruit with carbohydrates, high fiber content and vitamin C. But, to depend on Grapefruit Diet and make it the basis for a weight loss program does not make sense. Recent discoveries have thrown more light on the grapefruit. The recent Grapefruit Diet plans comprise very low calorie diet plans (VLCDs). These programs are not the right solution to weight loss. The conventional Grapefruit Diet involves a 7 or 21 day eating plan.

A study based on "Grapefruit Diet" was conducted by Dr. Ken Fujioka. He monitored the weight and metabolic factors, including insulin levels in 100 men and women who participated in a study by Scripps Clinic, San Diego, California. It was found that on an average, participants who consumed half a grapefruit with every meal lost 3.6 pounds and those who drank grapefruit juice thrice a day shed 3.3 pounds. Interestingly, many patients lost more than 10 pounds. The researchers are of the opinion that the chemical composition of grapefruit affects insulin levels and brings it down and encourages weight loss. Grapefruit can be added to the diet but it is not likely to be useful in bringing about weight loss.

The Grapefruit Diet promises a loss of 10 pounds in twelve days without starvation. The Grapefruit Diet permits three meals per day with a bedtime snack. The pink grapefruit also contains beta-carotene, which helps in reducing cholesterol level and builds a healthy heart. The Grapefruit Diet is extremely low in calories and is insufficient for daily requirements of the body. Long term success in losing weight with Grapefruit Diet is seriously in doubt.
