Anytime, anyplace, anywhere, would I swap places with someone needing to loose or gain 20 pounds to get to their goal weight.

Shasta - I'd bet your Metabolism is fairly high compared to most people here. My guess is if you are doing LC and not losing weight, you are not consuming enough calories. My guess is you are not getting enough fat (good fat, omega 3's) intake. Have to tested to see if you are in ketosis?

Cyprinodon - you say your BMR is 1680? Did you make any adjustment for activity level? Your calorie requirement could almost double depending on how much you exercise per day, and how active you are, and how high your metabolism is.

The Calculators are just a starting point for people who have no clue what their body needs. The better you know your own body the less you need to rely on a model to tell you what works and what does not.
