You ought to look up nutrition facts, and the benefits of various foods.
Cabbage and Apples have good fat-burning qualities (Apples have pectin, which is also very good to help your galbladder in digesting the fats.) Forget what cabbage has, lol. You can make some really good cabbage soup and eat it all through out the day for a couple days of the week, using chicken stock, lotsa veggies and stuf. It flushes the bad stuff out of you too. I did it for a while, and once in a while I still make it.
Also a good thing for your body (Though it might make you feel icky at first) is to make breakfast your biggest meal. Maybe even eat dinner as your breakfast. I did this too, and it sped up my weight loss. Also, this should be obvious but if you drink colas and tea or coffee, don't use sugar, but a substitute. (It was so hard for me to give up cola, but coke zero and pepsi max taste fine considering they're diet.)
