Thanks for the info, I'll have to look into it further. My blood sugar/insulin response is very sensitive to carbs, so the amount of lentils I use is very small. I add more if I'm going directly into a workout.
I ended up with this recipe after years of trial and error. It's designed to be high in protein, devoid of sugar, high in fat, and include a small amount of low-glycemic index carbohydrates. The high fat content seems to slow down the absorbtion of the other nutrients, moderating my insulin response.
