I’m just getting started (again) with keto and fasting. Hadn’t ever done a fasting insulin test before. This week it turns out mine is 12.7, which, while not catastrophic, certainly explains a lot of my problems getting weight to stay off. HbA1c has gone from 6.0 to 5.7 with my “mostly” ketogenic lifestyle. Looks like I need to step it up.
I have managed to move my “set point” down incrementally with 4 or 5 day fasts, but I did not have any idea about the insulin measurement. Now I have a target that is not just my weight to focus on. Wish I had measured before those first fasts.
