Some of the skinniest people i know eat loads of sugary treats and don't add a pound.

My girlfriend tried all sorts of different diets and products, most without success. Her friend let her try out a new Green Tea product she was using and she now swears by it.
Shes lost over 13 pounds already, most of the weight went from her tummy, hips, bottom and thighs. Apparently the Green Tea boosts your metabolism.
She got her own supply for free too, only had to pay like $4 shipping.

actually you may lose weight but low fat foods usually contain little nutrients. You probably could lose weight eating sugar cubes but i believe if you eat to many it would get stored as fat, not sure though...

no , sugar turns into fat in your body, and carbs turn in to sugar. get it?

No, sugar is a carbohydrate. Sugar is a carbohydrate which is easily and quickly broken down in the body and carbohydrates are stored as fat in the body.
We still need carbohydrates. Keep away from sugar. Starch is good.

Sugar is the single worst thing for your healthy diet. It is the one item that you're body gets absolutely no benefit from. For example, your body must have a certain amount of fat to function properly, but if your body never had sugar again, that would be okay. Food has to get it's taste from something. If you eat a "fat-free" food, you can be assured that it's high in sugar (or a synonym of sugar). Likewise, if you eat a sugar-free food, it's probably high in fat...Eating regular food in reasonable portions will solve all those problems...good luck!
