Here's a study that proves what I have said all along. The more you exercise, the more the effect on blood sugar. Just getting back to a regular work out and ride schedule has helped me cut my insulin intake dramatically. And, for me, the longer the duration, the longer the effect lasts. In my humble opinion, the first thing doctors should prescribe to a new type 2 diabetes patient is exercise, and plenty of it. Lower the carbs, move your butt, and keep a positive outlook. Just what the doctor should have ordered, but the first thing seems to be pills. I guess there's no money in prescribing diet and exercise, so this is what we get!
