Yes it has had a great effect. My Diabetes Dietitian said that the phase 2 SBD is ideal if not too strict for a type 2 diabetic. Since I enjoy the diet so what if it is stricter? Now with the Metformin, the phase 2 SBD is giving me control of my blood glucose levels. Actually, I have found for myself, that for some items, phase 2 is not strict enough. That is what frequent testing, at least 2 to 3 times daily, is all about. I am now enjoying the (1) diet, (2) the control, and (3) the results.
BTW, as far as results go, I had a 108 BG at waking today and an 80 BG before lunch!
Looking back I wish I would not have slipped off of the SBD about 3-4 years ago, gained the recent weight and became a type-2 Diabetic. But it happened, so instead of fretting about it, I plan to go back to what worked, the SBD, and live life to the fullest.
I am a Phase 2, 64 YO retired, a type-2 diabetic, still a Gym Rat!
