New Evidence Grapefruit Can Boost Weight Loss
Back in the 1980s, the Grapefruit Diet was touted as the miracle weight-loss solution for weight-conscious Americans. Like many other diets that centered on a magical ingredient, the diet itself proved to be no more than a fad. Although it doesn't kick start your metabolism, new research does indicate that there may be something beneficial to including grapefruit in a weight loss plan.
Scripps Clinic Follow-Up Study
Researchers at the Nutrition and Medical Research Centre at Scripps Clinic in San Diego did a follow-up study on how and why grapefruit might help with weight loss. The original diet probably caused weight loss because total calories and foods were restricted. Researchers confirmed that the benefits of the diet were a myth. However, they did find that grapefruit added to a healthy, balanced weight loss diet does have some positive effects.
The scientists studied two groups of participants. The first group ate their usual meals and added half a grapefruit or a serving of grapefruit juice to each meal. The second group actively tried to lose weight but did not include grapefruit or grapefruit juice in their diet. The researchers found that over a 12-week period, those who ate grapefruit lost an average of 3.6 pounds while those who drank juice lost 3.3 pounds. The non-grapefruit group didn't lose weight.
Grapefruit Can Lower Blood Sugar Levels
Grapefruit has the ability to lower blood sugar levels in much the same way that some diabetic medications do. It improves insulin sensitivity, which affects how the body's cells respond to insulin – the hormone that regulates blood sugar. When insulin sensitivity improves, patients typically have decreased appetites, which may be why they lose weight.
If you want to add grapefruit to your diet, however, check with your doctor. Unlike many other citrus fruits, grapefruit can interact with a number of medications. Contact the Metabolic Research Center for more information or help to lose weight while eating real food.
