Wikipedia "a negative calorie food is a food that is purported to require more food energy to be digested than it provides". The brief synopsis also says there is no scientific proof, but the list consists of none other than fruits and veggies! Shocking, right? Sorry, that cheeseburger didn't make the list. My idea of heaven....mac n'cheese burning more calories than the calories it actually has. Can I get an AMEN?!
So what does this actually mean? Eat your fruits and veggies, regardless of the scientific proof, or lack thereof. If you watch the news, read the magazine covers or hit the gym...you get a consistant message: eating fruits and veggies is truly the best thing for you.
