I am an insulin dependent 55 yr old 83kg powerlifter.
I take a slow releasing insulin at night and fast acting with meals.
This morning I got up and BS was 104 (took my slow releasing Insulin at 9 pm last night) At the end of my Bench session where I was benching 500lbs my BS was 223
Should I take my fast acting Insulin to counter act that spike?
I train at 5 am and the only food in my belly is a cup of coffee.
Wait - You are 55 years old, 83 kg, and bench 500 lbs?
And I would not take your fast-acting insulin until you are ready to eat in the morning.
I am a type II and notice a similar issue. I have found that if I eat half an hour prior to lifting that I don’t get a post-training spike. My “hypothesis” is that my pancreas gets triggered from lifting that my muscles need energy so it dumps glucose. If I eat prior I already have enough fuel in my muscles that I avoid the dump. I am curious if the good Drs’ would agree?
The pancreas does not store, and therefore cannot “dump”, glucose. In the setting of stress, there are a number of complex regulatory/counter-regulatory hormone changes related to insulin, glucagon, growth hormone, cortisol, and others that contribute to what we ultimately observe as fluctuations in blood glucose.
