Among the fads of the 1980s were Rubik’s Cube, Magic 8 Ball, and Pacman. There also were fad diets, such as the Beverly Hills Diet, the Cabbage Soup Diet, and the Grapefruit Diet. And each of them received underwhelming medical support. Read: 8 Diet Myths Exposed
Let’s take a closer look at the Grapefruit Diet. It seems there might be something worthy going on there and newer research shows the grapefruit diet was not all fad and no facts.
1980’s Grapefruit Diet Review
Despite having no affiliation with the Mayo Clinic, or even receiving a recommendation from them, the Grapefruit Diet is often referred to as the Mayo Clinic Diet. The diet promises a weight loss of 10 pounds in only 12 days.
A typical day’s meals on The Grapefruit Diet are a breakfast of half a grapefruit, two pieces of bacon and two eggs. Lunch is half of a grapefruit, as much meat as you like and a salad. Dinner is half of a grapefruit, fish or meat with another salad or vegetables instead. You are also allowed 8 ounces of skim milk before bedtime.
The contention of the diet is if you eat half of a grapefruit before every meal you will be less hungry and eat less. It also claims that grapefruit has an enzyme that helps to burn fat although there is no scientific proof to support this. Read: Is There Truth to Fat Burning Foods?
Nutritionists concluded that while the diet does produce weight loss, it is due to a significant reduction in daily caloric intake and not any magic fat burning principles of grapefruit. It is further said that the daily caloric intake allowed by the diet is unhealthy and once the diet is stopped the weight will be regained. As such, the diet has been kicked to the curb.

A more recent study has found that grapefruit may promote weight loss.
Revisiting the Grapefruit Diet
A more recent study conducted by the Nutrition and Metabolic Research Center at Scripps Clinic found a relationship between grapefruit and weight loss. The simple act of adding grapefruit and grapefruit juice to one’s diet can result in weight loss. This can be accomplished by eating half a grapefruit or drinking 4 ounces of grapefruit juice before every meal. And you don’t have to restrict yourself to the demands of the old grapefruit diet meal plan.
For the study, 100 participants were divided into three groups. The first group ate half a grapefruit before each meal, while the second group drank grapefruit juice before each meal, and the third group made no changes at all.
At the end of 12 weeks, the first group lost an average of 3.6 pounds, the second group lost an average of 3.3 pounds, and the third group, an average of 0.5 pounds. In also was discovered that the participants who ate grapefruit had lower insulin levels — the hormone that regulates blood sugar and fat metabolism.
The results suggest that the relationship between insulin, metabolism and fat storage, may be what contributes to the weight loss power of grapefruit. Read: How to Boost Metabolism and Lose Weight
And the bottom line is researchers believe that the chemical properties of grapefruit may help stabilize insulin spikes. And this helps promote the breakdown of food for energy instead of storing it as fat.
WARNING: Grapefruit juice and fresh grapefruit can interfere with the action of some prescription drugs, as well as a few non-prescription drugs. Read the FDA Consumer Update and ask your doctor or pharmacist.
