How can I find out what specific food helps me lose weight. I understand that everyone's body type is different so it will be different for everyone. I have a body type B, but is there some way I can find out what food makes my body drop weight? (For example, a friend of mine discovered that her food was celery. So the more she ate celery, the more weight she lost.)

Its called "The absence of" food. I'm sure you have heard of it.

It's not a certain type of food, it's the food you are eating already that is keeping weight on. If you stop eating bread, rice, pasta, corn, sweets like cake cookies, ice cream you will lose weight fine and fast. Eat more fruit, veggies and protein, drink only water and green tea. In a month you could drop a couple of sizes.
