The grapefruit diet started in the 1930's with Kelly D. Brownell, PhD.
There are different types of the diet but all based on eating half a grapefruit before meals. Grapefruits are non fat, low sodium, low calorie fruits, low in carbohydrates and high in fiber and vitamin C. It is believed that the enzymes in grapefruits help with appetite suppression, increasing you metabolism and burning fat. Research seems to support the increase of weight loss by eating grapefruit or drinking grapefruit juice prior to a meal.
The grapefruit diet is only a solution to begin your new life habit. Remember the universal truth with losing weight focuses on eating nutritious food in less quantities and drinking no calorie or low calorie liquids in large quantities.
