What about the popsicle diet?

sugar will make you fat faster then fat will.

sure you'll lose weight on that diet, but its a terrible way to do it.

I would think any of those diets where you replace two meals a day with some specific other food or drink would be the same.  Whether it's a popsicle, an apple, or a milkshake, the weight will most likely come back once you start eating normally again.  The way those diets work is by giving you a specific food or drink for two meals, so you eat those calories rather than the ones in whatever you usually eat at those meals.  However, when you go back to eating what you usually eat for those meals, you're getting those calories back, so the weight comes back.  The only way to keep the weight off would be to keep restricting your calories for those meals. . . probably easier to just count calories to begin with than crash-diet first and have to learn the lesson later.

That's probably a good idea, although I would probably substitute Fudgesicles, as it's usually chocolate I crave for dessert ^_^ .  I'll have to check the nutrition information on the fudgies. . .
