My question is, the second time through, why was his blood glucose 68 going in? He only took the resistant starch 30 minutes before.

I'm not diabetic, but when I work out, my blood glucose typically rises 20-30 mg/dl. It went up 40, that's only happened once. Over the last half-week, I've cut my protein down to 30 grams a day or so, just to see what happens.

One thing that happened is that my blood glucose when working out doesn't go up so much. So far, anyways, I'll see what happens today. It's possible Steve's glycogen levels were lower that day, so he didn't get as much of a bump from exercise, or his insulin was lower, free fatty acids and ketones higher, so his body didn't see as much of an energy crisis when he started swinging that kettlebell.

Incidentally, my best workout this year (based on how I felt working out, not performance--performance was better than usual, but I don't keep very good long-term records)--was one morning when I woke up with blood glucose in the low 60s.
