Grapefruit is Exonerated Decades Later
In 1930, Kelly D. Brownell, PhD, introduced the grapefruit diet. At the time, she couldn’t have known this eating plan would fascinate those desperate to lose weight for decades. The grapefruit diet hit a fevered pitch in the disco era of the 1980s. Besides doing aerobics while wearing colorful legwarmers, dieters in this time period often consumed grapefruit multiple times each day. Proponents of the grapefruit diet believed this tart food consisted of certain enzymes. They felt consuming these enzymes before eating other foods would speed up their metabolism to help them burn fat. At this time, researchers debunked the grapefruit diet as ineffective. Surprisingly, more than three decades after the grapefruit plan was dismissed as another dieting failure, it has been given new life — but not as a fad diet.
Scientists at the Nutrition and Medical Research Center at Scripps Clinic in San Diego, CA, divided 100 obese people into three study groups. One group consumed half of a grapefruit before breakfast, lunch, and dinner. A second group drank grapefruit juice before each mealtime. The last group of participants didn’t consume any grapefruit products before eating their meals. After the 12-week study ended, the group that consumed grapefruit lost an average of 3.6 pounds while the participants who drank grapefruit juice lost an average of 3.3 pounds. The volunteers who avoided grapefruit products lost an average of 0.5 pounds. In addition to losing weight, those who consumed grapefruit products also possessed lower levels of insulin.
Grapefruit Lowers Insulin Levels*
The scientists’ findings suggest grapefruit consists of plant compounds that may promote weight loss by decreasing insulin levels. Elevated insulin levels may make you feel hungry more often. High insulin numbers might also prevent your body from effectively breaking down fat. Packed with vitamin C, fiber, and potassium, grapefruit is a wonderful food to incorporate sensibly into your diet. To prevent diet boredom, you likely won’t want to consume grapefruit products multiple times each day. Simply eat it whenever you crave something tart.
