Interesting. I tried it out saying "little or no exercise" since I have not been getting much during the winter, and it tells me:

Maintenance:
2153 Calories/day
Fat Loss:
2080 Calories/day

That's a pretty fine line between maintenance and fat loss, less than 100 calories a day. How does one even calculate to that level of precision? I mean I can weight and measure every bite, and I often do - but there is no guarantee that the actual calories of the food I'm eating match up with what the charts say. But they are right, I sure am "maintaining" at that level - stalled for 16 months, and average caloric intake of 1900-2200. Of course the above seems to say I should lose at 1900. I'm willing to believe I should eat less. The only problem is that when I do I get hungry. I can seem to live with hunger for 3-4 days, and then end up exploding on a 4000-calorie binge. But if I stick to the 1900-2200 range I can keep it up indefinitely. Just can't lose weight on it.
