Study was on type 2 but paleo had a better response than the gov recommended diabetic diet.
Beneficial effects of a Paleolithic diet... [Cardiovasc Diabetol. 2009] - PubMed - NCBI concludes that "Over a 3-month study period, a Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a Diabetes diet in patients with type 2 diabetes." So paleo shows better results than the whole grain diet pushed by big agra and big gov.
Eating primal is not a diet, it is a way of life.
