I’m 5-6, 155lbs.
By the BMI calculator, I’m obese.
I do believe at 122lbs, the bottom of the “normal” range I’d look like a POW survivor....
I think at the bottom of the normal range is usually too skinny, myself. I opt for the high part of the normal range, and my doctor says that’s fine. Also, I think there’s an age/gender related BMI calculator. I bet you are closer to normal or maybe overweight if you use that. You don’t sound “obese” to me.
