Grapefruit Diet That Will Actually Help You Lose Weight


The Grapefruit Diet, which is likewise called the Hollywood Diet plan, has actually been making the rounds since around the 1930s. Advocates vow it helps them lose weight, and claim that grapefruit has a fat-burning enzyme.

The majority of wellness professionals have actually disagreed in the past, calling the diet plan a fad, and stating there’s no indicator grapefruit burns fat. A brand-new research study, nevertheless, reveals that not only does grapefruit help dieters drop weight, it could be as good as prescribed drugs in controlling blood sugar level levels.

Analysts at the University of California, Berkeley, found that mice that ate a high-fat diet for three months gained 18 percent less weight when they consumed grapefruit juice than a control group that consumed water. In addition, the mice in the grapefruit group had enhanced levels of glucose, insulin and triacylglycerol, which is a good type of fat.

Mice were divided into six groups. One group consumed only water, and the other 5 groups drank grapefruit juice diluted with water at various concentrations with a little bit of saccharin to neutralize the grapefruit’s bitterness. The water of the control group had glucose and saccharin added to match the calorie and saccharin material of the grapefruit groups.

At the end of the study, mice that drank grapefruit juice gained 18 percent less weight than mice in the control group, and their blood glucose levels decreased by 13 to 17 percent.

The researchers also checked a flavonoid in grapefruit called naringin, which specialists think is a vital to weight loss. While one group of mice was given naringin, another group was offered metformin, a drug frequently offered to Type 2 diabetics to lower glucose levels. Members of the two groups were fed a diet that was either 60 percent fat or 10 percent fat for 100 days.

“The grapefruit juice reduced blood glucose to the same degree as metformin,”

stated co-researcher Joseph Napoli, professor and chair of dietary sciences and toxicology.

“That indicates a natural grapefruit drink decreased glucose levels as successfully as a prescribed medicine.”

Naringin’s effect on glucose levels was much more obvious on mice provided the high-fat diet, however it had little impact on weight. That suggests, analysts state, that another ingredient in grapefruit is liable.

“There are numerous active compounds in grapefruit juice, and we do not constantly comprehend how all those compounds work,” said co-researcher Andreas Stahl, associate teacher of dietary sciences and toxicology.

The researchers, whose research study will be published in the journal PLOS ONE, were skeptical before they started the research and were surprised by its outcomes.

“I was surprised by the findings,”

said Stahl.

“We even re-checked the calibration of our glucose sensors, and we got the exact same outcomes over and over once more.”

Stahl and co-researcher Napoli eliminated normal factors for weight reduction. Both groups consumed the same quantity of food and participated in the same amount of activity.

“We see all sorts of scams about nutrition,”

said Napoli.

“But these outcomes, based on regulated experiments, necessitate further study of the prospective health-promoting homes of grapefruit juice.”

The Grapefruit diet plan has a number of versions, however many are a protein-rich, low-carb plan that calls for grapefruit juice at every meal, and guarantees quick outcomes– as much as 10 pounds in 12 days. Many Hollywood celebrities, including Kylie Minogue and Brooke Shields, have actually praised the diet plan.
