Well, I've been dieting for a week. I'm down ten pounds, I know it's mostly water weight but it's still a good feeling. I've been on a fairly severe caloric restriction. According to FitDay.com my base metabolic rate puts me at ~3400 calories a day, they recommend I cut 1400 calories to loose weight. This would mean eating roughly 2000 calories a day. I've been trying to stick to 1700-1900. It seem to be working really well. Also, as an unintended bonus on the days I do "splurge" a 2100 calorie day feels like a lot of food.
