I know there are a ton of calculators out there. I also know they are wildly inaccurate for very heavy people, since we obviously have a much lower percentage of muscle to fat. In other areas of this board I'm reminded to eat "close to my BMR" or my metabolism will slow down. Well, I'm pretty sure I'm not losing any weight on 2100 calories a day! I'm guessing I should be around 1500 to lose weight - but like I said, I'm just guessing.
