Plant-based w/low fats & low GI food should work, if you ever decide to move away from keto. Last I read on this, there have been breakthrough cases of diabetes essentially vanishing & insulinoresistance being reversed.

I'll try to link the studies if I can remember later. For what it's worth I'm not diabetic but did keto for 5 years & it was the best I had felt mentally and physically my entire life. That said, keto is also not just "low carb", it's essentially "no carb", and I'd recommend a plant-based diet with proper macronutrients control over it.

Low-carb is extreme. It's also a fad diet. The majority of studies state that as fact. The human body wasn't designed for low-carb. Just because your particular medication requires it doesn't make it less extreme overall.
