Well, I'm just confused about what my body is telling me. I posted yesterday saying that I'd been so hungry all day that I'd eaten nearly 3,000 calories worth of low-carb food (all good, nourishing stuff, but still!)

I resolved to do better today, and today I wasn't nearly as hungry, so it went fine. But here's the weird thing -- after eating so much yesterday, I felt FREAKISHLY good today. I had so much energy I practically doubled my productivity -- really! I worked out, and could bench press about 15 pounds more than normal. I tacked on an extra 20 minutes to my cardio. At the end of the day I had so much energy I cleaned a closet I'd been meaning to clean for three months. What on earth is my body saying to me? That it likes to be fed 3,000 calories of fat and protein a day? That it NEEDS it? I mean, come on! I'm a short, mid-thirties woman here, not an NFL linebacker!

But here's the weirder thing: I didn't gain an ounce.

I just find it physiologically bizarre that I could want to eat that much, and that I could eat that much and not gain weight, and that it so obviously agreed with me. According to the formula for the Basal Metabolic Rate another poster mentioned below, my BMR should be about 1406 calories a day. Even with my workouts, how could I be burning more than 2,000 calories a day, max?

Incidentally, does anyone know why Fitday thinks I'm burning 2,700 calories a day? Don't they use the same formula to calculate BMR?

I'm just baffled. I'm not complaining, really, I just don't get it.
