OverviewThe grapefruit diet entails eating grapefruit or drinking grapefruit juice at every meal. According to the American Dietetic Association, the grapefruit diet first became popular in 1950 and is also known as the Hollywood diet.
How Is This Diet Supposed to Work?The premise of this diet is that grapefruit contains fat-burning properties. However, there is no research to support this theory.
What’s Involved?There are many variations of this diet, but in general they all entail consuming grapefruit with meals. The older versions of this diet are also very restrictive in the foods that are allowed and are, therefore, very low in calories.One common version of this diet consists of eating four meals per day, with grapefruit included at three of these meals. Other foods allowed on this particular version include as much black coffee as desired, eggs, and meat. A sample daily meal plan may look like this:
|Meal 1|| |
|Meal 2|| |
|Meal 3|| |
|Meal 4|| |
What the Research SaysWhile there is no research to support the theory that grapefruit has fat-burning properties, a recent study conducted by the Scripps Clinic in California found that adding grapefruit to each meal for 12 weeks resulted in greater weight loss. Because this was a relatively small study and the first of its kind, more research is needed to support these results.
