(From another site....)
have you ever heard of negative calorie foods?
well, i just read about it at my mom's book, "negative calori foods".. okay.. i'll explain it to you..
well actually there isn't a single food on earth that has 0 calorie. but there are many foods, usually fruits and vegetables that could cause negative calories to whoever eats it. well.. for you to further understand.. there are foods containing less calories than it needs to digest them. for example.. there's this one calorie food that has a total of 100 calories. and i takes 150 to digest them.. so it means that by simply eating this negative calorie food, you're able to burn 50 calories! so, that means.. the more you eat the more calories you burn.
and of course, in order to stay fit, you should burn up all the calories that you ate and if you still have stored calories in your body as fat, you should burn them up also!!
so here are the lists of the negative calorie foods..
