oh, I put my stats in those calculators, and all I have to say about the results:
BALD! FACED! LIES!
So what I did was I used FitDay to track my calories for a month. I also weighed myself a lot. When I lost weight, I did a 7 day average and a 14 day average caloric intake. When I gained, I did the same.
This gives me a picture of what my body is doing with calories in and calories out. At the moment, I know that my body needs 800 calories less than what those calculators say in order to lose weight. That is a big, big difference.
Do the work yourself using FitDay and your scale and find what works for YOU. Otherwise you're setting yourself up for a whine tasting party.
