I'll keep this as short as possible:
If someone was chubby/fat their whole life from age 1-17 (20% fat), then suddenly became physically active and trimmed down to 10% fat and kept it off for 2 years, would that person be considered lean or fat? I dont mean appearance-wise. I mean in terms of genetics.
I ask because weight gain/weight loss rules (i.e. muscle loss/fatloss, and muscle gain/fat gain) differ for fat and thin people. Fat people put on fat faster, etc...
So would I be fat, or lean?
