The 3 day diet has been around since the mid 80’s. It promises quick weight loss up to 10 pounds although most of that weight will be water pounds. The proponents of this diet are quick to tell you not to go beyond three days with this diet. Eat your regular diet for 4 or 5 days before beginning another round of the 3 day diet.

The key to this diet is to make sure to exactly follow the diet, which in under 1000 calories a day. That’s not many calories. So after 3 days of it you will probably be very hungry and ready to pig out.

As you probably guessed the consumption of grapefruits is prominent in this diet. Grapefruit juice along with breakfast, grapefruit juice along with lunch and for a little variety a half of grapefruit or grapefruit juice with dinner. But not grapefruit juice for the bedtime snack (I guess that would be a little too much)

As for what you eat with your grapefruit juice, meats, fish and fresh vegetables are okay, but starches are off limit. And you have to drink a lot of water each day along with that grapefruit juice. (Lots of trips to the bathroom)

Why grapefruits?

Apparently the reasoning behind the large amount of grapefruit juice is the theory that grapefruits are fat burners. There isn’t any evidence to this. But grapefruits are a good source of vitamin C and fiber.

It is never a good idea to go on any diet that promotes quick weight loss such as the grapefruit diet. You might loss the weight quickly but you will surely gain it back just as fast.
