There is some research that shows eating half a grapefruit with meals three times each day can help people lose small amounts of weight, about three or four pounds in 12 weeks. However, there's a big difference between eating grapefruit within an overall healthy, balanced diet vs. following the standard grapefruit diet, which I don't recommend for anyone.

"This is a diet that truly works. I did it religiously for two months and lost about 22 pounds. I have tried many diets that left me hungry and depressed. With this diet I ate normal foods and actually felt full and revitalized." -- An iVillager

"My sister and I tried this diet and I gained a lot of weight, while she lost weight. I think this diet has to agree with your body type. Really, it's not for everyone." -- iVillager cookie_88keys
