The Grapefruit Juice Diet

So last weekend I tried the grapefruit juice diet. So here is the diet stats:

what is allowed:

Fresh Fruit 

Water

Grapefruit Juice (I did Ruby Red)

You have all of those all day long

For dinner it is a sensible meal

Day 1

Bone less skinless oven roasted chicken breast 

Green Beans

Yellow Squash W/Onion

Day 2

Oven baked flounder 

White Rice

Steamed Broccoli

With this diet I had low energy. I did drink about one 32 oz bottle of juice a day. In all I didn't like this diet. There was not more bowel movements, just a tired feeling all day.After 2 days I lost a total of 3lbs. Its just not a diet for me.
