Grapefruit Diet Blog & not only!

No one knows who first created the Grapefruit Diet, but since it first emerged it’s drifted in and out of being vogue, usually brought back into the spotlight by celebrities who decide to try one of the dozens of variations. The mainstay of the diet revolves around eating half a grapefruit or drinking an eight-ounce glass of unsweetened grapefruit juice before each meal. Proponents of the diet claim that grapefruit has a fat-burning enzyme, helping you eliminate fat, and their claims may not entirely off. A study from a 2006 issue of the ‘Journal of Medicinal Food’ revealed that people who ate half a grapefruit before each meal for 12 weeks lost 3.6 pounds. Likewise, people who drank a serving of grapefruit juice three times a day lost 3.3 pounds. However, many individuals in that study lost more than 10 pounds. Researchers suggest that grapefruit may lower insulin, which is a fat storage hormone. Yet it’s important to note that in this study, individuals ate healthy, balanced diets and could exercise up to three times a week. Note that this is substantially different from the Grapefruit Diet, which takes an unhealthy approach to weight loss and will inevitably set people up for diet failure.

Is the diet healthy?

No. Although eating a half a grapefruit or drinking a glass of grapefruit juice with each meal is a good way to sneak in three daily servings of fruit, eating only 800 calories a day total is neither sustainable nor healthy. It could put you at risk for nausea, dizziness, and vitamin and mineral deficiencies that could cause problems with hair loss, your immune and nervous systems and your bones. Also, if you’re on certain medications, including some antidepressants, immunosuppressant drugs, and drugs to treat high blood pressure, high cholesterol and arrhythmias, grapefruit could interact with those medications.

What do the experts say?

“Any diet that’s this low in calories and cuts otherwise healthy foods is extremely unhealthy and should be avoided,” says Dawn Jackson Blatner, R.D., L.D., national media spokesperson for the American Dietetic Association and a registered dietitian with the Northwestern Memorial Wellness Institute in Chicago. Blatner also can’t say that grapefruit is truly the magical component here, for any time your caloric intake drops this low, you will lose weight. “Yet as soon as you return to regular eating, you’ll gain it all back — and then some,” she adds.

Who should consider the diet?

Nobody

Bottom Line

The possible weight loss potential of grapefruit aside, this diet works only because it restricts calories to severely low levels. Even if you are sedentary, it’s impossible to function on 800 calories a day. And the fact that exercise is discouraged is never a good thing.
