Grapefruit Juice Diet Plan: How It Works?
The grapefruit is believed to have fat burning enzymes that helps in eliminating fat. The most important active ingredient in grapefruit that helps us to lose weight is naringin, a flavonoid compound that gives grapefruit its characteristic bitter flavor. It blocks the uptake of fatty acids into cells to prevent our bodies from effectively using carbohydrates.
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. Yet in this study, individuals ate healthy, balanced diets and could exercise up to three times a week.
Researchers theorize that the grapefruit assists in the management of insulin levels. After the study was complete, individuals taking grapefruit had lower levels of insulin and blood sugar than beginning. The levels of insulin remained unchanged for those who didn’t included grapefruit in their diet.
Lower levels of insulin may promote weight loss because with high levels of insulin, sugar is more likely to be stored as fat, thus prevent the body from breaking down fat. Also, high levels of insulin will make people feel hungry so that they eat more.
