I read a very interesting article from MSNBC.com just now and it tells how we can burn more fat during workout. It's simple...Don't eat before you exercise. The scientist suggest that since our body is low in food and doesn't have carbohydrates to use as energy during exercise, it will use our fat reserve as fuel instead. A study was conducted to prove this theory and their findings were favorable. The group who didn't eat any carbohydrates during workout burned a significant amount of fat than those who ate. This mean exercising on an empty stomach isn't so bad after all..
