7 day water diet.

I'm a vegetarian for personal reasons and have been for 4.5 years. I enjoy it.

BUT I also eat a lot of food, even while losing weight. I've never heard of the 7 Day Water Diet, but anything that severely restricts caloric intake or food groups sounds like a bad idea to me.

The goal is sustainability. Even if you crash diet and lose a lot of weight very quickly, you still have to learn how to eat real food appropriately if you want to keep the weight off. Think about how you want to eat for the rest of your life and then figure out how to work it into your lifestyle.
