I weigh daily, first thing in the morning, always looking forward to the result. I bought a beam balance and have been weighing for the past few months as I deliberately try to lose weight. I'm presently half way from 161 to 135. It's been quite a mystery why weight sometimes goes up when I think I'm eating ok.
I discovered Fitday only three days ago and now I'm really excited to weigh all my food and get a handle on calories, carbs, etc. Now I can get serious about following a strict very low carb diet. Weight is already plunging!
