The Grapefruit diet is another fad diet which is more of a detox, and helps with rapid weight loss.
A diet based on grapefruit consumption for weight loss is not and should not be considered a long term diet plan.  The diet plan is designed to last for twelve days at a time.
The grapefruit diet dates back to the days of early Hollywood.  The diet has changed over the decades, but it’s basis is still that of a fad diet.
The grapefruit diet is intended for quick weight loss.  If you want to lose weight for a special occasion that lasts one night only, this diet ranks right up there with the Cabbage Soup diet in terms of quickly slimming you down by helping you get rid of excess water weight.
Grapefruits have been found to have properties that affect the body’s metabolism.  The grapefruit can actually help to speed up the metabolism which translates into more calories burned.
Grapefruits are considered a low glycemic index food.  That means that it stabilizes the blood sugar which controls the appetite.  It is a low enevrgy density food and it is a known diuretic (removes excess fluids from the body).
The grapefruit diet can be followed for twelve days with a two week break between cycles.  Since the diet is a quick fix trend diet, performing it regularly is not healthy or wise.  A quick drop in weight for an event is one thing, but becoming a regular grapefruit dieter is not good.
Grapefruits are eaten with each meal.  There aren’t a lot of carbohydrates with this plan.  You can eat eggs and bacon for breakfast minus the toast, but don’t forget the grapefruit.
