Great link Kari, proof that there is a lot of variability among diabetics beyond the T1 T2 division.
This study suggested some results for a portion of the population that carries a specific gene. Those people may be at increased risk of heart disease, diabetes and decreased body fat.
There is still some real controversy over whether body fat may actually be protective for older adults. And it has even been suggested increased body fat improves cognitive function in elderly women.
I wonder if this gene IRS1 is something you could get tested for?
