I was just wondering this the other day. Obviously some if not most of us can find out how many calories we need in order to lose weight, and it works, but I wonder how accurate it really is. I wonder this because a few days ago someone sent me one of the calculators they liked and said they trusted, and I plugged my stuff in:
age: 20
height: 4'9''
weight: 170
and suddenly a button popped up that basically said, "the height you have selected cannot be correct. allow us to fix it for you."
and they changed my age to 11.
I laughed out loud, but then I stopped to think about it. They're just machines and can't really see us or what we're made up of, so I wonder if, the more I get closer to a normal weight for my height, it will get easier to be more exact, and if right now is just a shot in the dark.
Does that make any sense?

I just woke up sorry everyone! lol
