My downfall is two things:
a) portion sizes, which have increased everywhere, but most of all, here in the USA
b) my body is insulin resistant, probably from genetics (both my parents are large and so were theirs).

Jus' because the portions are bigger does nae mean ye have to eat more.
If ye cook for yerself, ye can make the portions whatever size ye want!
If yer parents and grandparents are fat, then ye've been brought up thinkin' eatin' fattily be normal. That not be yer fault. But blamin' it on Nature when its really Nurture, that is.
I weigh a bit due to diabetes.
Perhaps ye be confused. Perhaps ye've got diabetes because ye weigh 'a bit'.
As ye've already said, ye were brought up eating fattily. That'd increase yer risk of diabetes.
If ye want, I be havin' a good recipie fer scurvy that works wonders!
If ye'r fat and need two seats, BUY two seats.
