My annoyance with all of these numbers is they are meaningless without some measure of size.

I'm literally twice the size of my friend, at the same BMI (more than a foot taller). So should I be eating 3400? Or should they be eating 850?

I think I have the answer.

You're supposed to:

- count your calories and maintain the same calorie intake for a while

- measure your body weight or other metric you want to change throughout

So, if you're eating 2,500 calories a day and see you're gaining weight, you have a baseline you want to go below to lose weight.
