But most people are fat!
So is the increase in diabetes just coincidental to the increased bmi of the population?
I don't know but it would be interesting to look at the figures.
Most T2s get insulin resistance years, if not
decades before they gain weight and develop T2.
Once the weight gain starts, the insulin resistance increases even more, and a fatty liver often develops.
The common feature for T2s is NOT being overweight and having a fatty liver. It is the insulin resistance which then causes the weight gain and fatty liver - which then becomes a vicious cycle of increasing fat, increasing insulin resistance and increasing T2.
Slim T2s may not be fat, but they DO have insulin resistance, and MAY have fatty livers. They may also have damaged beta cells which reduces their capacity to produce their own insulin.
Plus, of course, that not all T2 insulin resistance is caused by eating carbs. It can be genetic, environmental, caused by drug treatments... there are many other causes.
Personally, my insulin resistance comes from
- genetics
- a drug I take for another medical condition
- that medical condition itself
- AND being overweight.
The first 3 reasons pre-date my being fat by about 15
years.
As a result of these, my carb tolerance (before my blood glucose rises) is well below that of the carb intake recommended by the NHS. If I followed their diet, I would feel dreadful, have uncontrolled blood glucose and/or be on several medications. I would also be fatter.
I prefer low carbing.
