Yes, 3 days isn't enough time to tell anything. Please hang in there and keep following the rules! I had to document everything I ate to get an idea of what 18-20 carbs really looks like. I'm 2 months in and still document! also, if you must weigh in daily just write it down but take the weekly average and you'll see! I'm steadily 1 pound down each week, that makes me smile. I know I could cut my protein shakes, nuts, and my cinnamon/cream cheese/splenda dessert at night and probably do better, but I'm ok with that. It keeps me on track and I don't feel deprived of anything.
