I'm usually late to the party! Oh well
I picked the insulin one, however, I'm not sure I would agree that is MOST people.
This WOE is perfectly designed to combat the insulin resistance/hyperinsulinism defect, and all its subsequent clinical fallout.
If I understand correctly the epidemiological stuff I've read, then it seems the range in the population for that may be something between 10 to perhaps 25%? And very possibly as population cohorts age, this trends toward that higher number as aging has its own impact on all our systems, including hormone regulation.
As someone mentioned, the insulin resistance problem is not necessarily identified purely by weight, as there are definitely some normal weight, or even thin, Type 2 diabetics around.
I'd like to see the day come where serum fasting insulin is a regular screening item, and checked on even in childhood. I'm sure that I probably had this quite early on (i was a fat kid right from the start!) and I would think that if they screened all the children now (especially those who are already getting obese as young'uns), they could quickly spot the kids who are insulin resistant,and get them started on restricted carb eating pattern now, rather than let them suffer through the years and be subject to diseases of middle age which may well be highly controllable, if not completely avoidable as one ages, not to mention the pain and ostracism of being overweight which those of us who were always fat kids know well.
I think there is also merit in some comments about 'relative' intake of carbs. Some people simply seem to feel and do better with more carbs than we insulin resistance types can tolerate.
