carbs==energy, unused energy==fat. I always eat carbs in the morning and afternoon, and never at night. If you really want to loose weight, just stop eating carbs. seriously that is the fastest way. However, loosing weight in my opinion is not very important. (Unless you are in a pull up competition) I'd rather be 5-10 pounds heavier and strong. Also if you are physically active and don't have enough carbs, you are VERY prone to injury. I hurt myself this way, so now I always make sure to eat a lot. I eat about 3000-4000 calories, and am about 7% body fat. Interestingly, before a competition, pro body builders don't eat any carbs to reduce their body fat. The day before they load up on carbs, both for energy and to "fill" their muscles.
