I wouldn't know that much, tch, but from what I've seen both on TV an' here at PC an' heard, americans are obese... well more than other countries are. o_o Hmm... tch, might have ta do with tha fact that colonists came from so many different populations that were usually sepparated that tha gene pool there got messed up... meh, tch, I can't say anything for sure.
Sugar? Tch, dunno about sugar, tch, but if they should remove some then they darn well better find it a good replacement, tch, 'cuz I like my sodas 00berly sweet! o_o
I eat junk an' drink junk alot an' don't do any exercise, tch, but still I ain't fat... tch, I agree that it's most certainly a metabolism issue.
