Whilst it can result in a short term increase pay attention to what it’s doing longer term? Both the next few hours and day and overall long term
If you are building muscle mass (which long term reduces IR) and overall health and the rise is temporary then maybe the short lived and maybe temporary rises are worth it.
Thinking about why it’s rising it means your body detects a need for more energy due to the exercise. that means the rise is coming from somewhere. Is it the excess glucagon in the liver being dumped? Is it better in the blood stream than “clogging” up the liver? I’m not certain of the answers but I don’t think it’s as simple as a short term rise being bad.
I would agree. I have only recently been diagnosed with diabetes. Although I have been weight training for some time, it tended to be late in the evening and usually shortly after a meal. Since been diagnosed 2 months ago, and learning about diabetes and in particular insulin resistance (IR) I have adapted my exercise regime. I have added a 20 min HIIT exercise in the morning, prior to eating. It took a few weeks for me to reach the full 20 minutes without pauses, because my heart rate would go off the scale. So I would pause for 30 seconds, or so and let my heart rate calm down and then start again. But with time my heart rate has settled, although my Doctor may argue that it is still too high during the exercise but I feel comfortable and I know my heart is healthy as I have had ECGs to confirm it.
As for my glucose levels, they always go up. At first by 2-3 mmol but over time they have also settled. And now will barely go up by 1 mmol. My “objective” is to drain my liver of all it’s stored glucose, ( I don’t actually know what my biology is doing in real terms). But over time I have noticed that my average daily glucose levels have dropped.
Along side the exercise I am focusing on reducing my carbs, not my calories. The idea being that I’m not allowing my body to fully replenish my glucose reserves in my liver, and therefore, long term reducing my IR.
So, personally, I would carry on with the exercises at the rate and pace you are comfortable with, so that you can stay interested and will continue. Be patient with your glucose levels and see how they settled over time. And to be on the safe side, ask you Doctor to run some tests on your heart, so that you are both comfortable that there is no underlying issues with your heart which my causes you other problems.
