This powerful study highlights what may be the most accurate marker in determining whether you are at risk for diabetes: your sugar readings one hour after a high-carb meal. Better yet, you can find out the answer on your own and at negligible cost. Chris Kresser has an excellent post with easy to follow directions, as does Jenny Ruhl here. I tried it out myself, and I didn’t like what I saw.
