The Grapefruit diet started way back in the 1930s, though back then it was called the Hollywood Diet. This diet is still very popular today and many people swear by it for fast weight loss.
This diet claims that the grapefruit contains special fat-burning enzymes that become active when the fruit is eaten along with a small portion of other foods at each and every meal.
For years medical professionals and nutritionists have said this was hype, that the grapefruit has no fat burning capability and that this was just another fad diet plan, like so many others on the market.
Today many medical experts still state that there is no evidence that the grapefruit is a magic bullet for weight loss, in fact Connie Diekman of the American Dietetic Association has stated that these types of diets perpetuate yo yo dieting, which, is on again and off again dieting, and a misunderstanding of what it means to lose weight in a healthy manner and on a permanent basis.
