Did you lift pre diabetes ?
I did and I am tall and thin and I am actually getting better results then before.
That might be cause I am more consistent now. I only managed 10lbs muscle in 10 months since my diagnosis but that’s 10 more then the years pre diagnosis. I have always been thin and I won’t get that huge look.
Strength is the same but I got 10 more pounds.
I am going to read that stuff jack16 posted. I do the low carb thing but need to learn how to bolus properly too.
Yesterday my sugar was at 190 after eating at a friends house so I just went to the gym and knocked it down to 95 in an hour. 190 that sucks , never goes that high when I eat my usual predictable foods at home.
Also maybe you are over training, I do that then I notice when I miss a few days I am stronger when I get back to the gym from the extra recovery time I may need now with this sugar problem.
