Measurements

Out of interest, I found a link off of WebMD's website that tells you your BMI (body mass index) and where you are on the healthy weight scale.

Not surprisingly, I'm underweight. My Healthy Weight Range: 104-141lbs.

Personally, I don't get that. You can't tell me that if I gained 15lbs I would be just as healthy as my sister who is closer to 140. She's overweight, and certainly not healthy (yes, I know there are other factors in there as well) but I think that range is far too broad to be appropriate.

My BMI is 16.1 and 'healthy' is 18.5-24.9 (again, holy range).

A different website says I should aim for 2413 calories per day to gain one pound per week. Also, it tells me that to maintain my current weight I'm only eating around 1500 calories per day. I know for a fact that's not true (I've kept food journals) and doctors have told me that that's approximate. Just like for people who lose weight, sometimes doing only what they tell you is just not enough so people have to eat less than they're supposed to (or in my case more).

I think in this case, I'll split the difference and try to gain half a pound a week, or about 2000 calories a day. I'll try to exceed that as much as I can see as I've tried that before and it didn't work but I'll give it another shot.
