You’re assuming that someone “becomes” fat in the first place. There are some people who are born overweight (even when the mothers were not overweight, and did not gain more than the recommended amounts during their pregnancies) — people who were NEVER “normal” weight in their entire lives, even when they were exclusively nursing as babies.[/quote]
again, if you look at the obese population of today, the vast majority “become” obese. yes, I agree with you, there are a small minority of the population that will always be obese via a combination of slow metabolism or susceptibility to the addictive potential of food or prenatal issues as mentioned by navydoc.
if you look at population data, you’ll understand what I mean.
if you go back to the 50’s, we had 10% obesity rate and 33% overweight rate, and no data on the severely obese. now we have 5% severely obese, 34% obesity rate and 33% overweight rate.
therefore, at least 2/3 of the obese population we are looking at today “became” obese from what was suppose to be overweight genetics. and 1/2 of the normal genetic population “became” overweight. meanwhile, 1/2 of the folks with obese genetics “became” severely obese.
