It could be an number of things. But it is highly unlikely to be fat. First off, 3lbs of fat would be 10,500 extra calories, and I'm pretty confident you didn't eat that much. Also, a gallon of water weighs 8+lbs. Low carb has a tendency to make you a little constipated, so it could be that. I wouldn't worry about it. It is really best to look at weight loss over a longer period of time, not daily. My weight can fluctuate 5lbs in one day, just from my normal eating and drinking cycles.
