Type 1 and Type 2 diabetes are completely different conversations, but regardless everyone should try to take lifestyle approaches to improving their health (in addition to whatever is medically necessary).

Even going very low carb, gluconeogenesis paths can still cause a diabetic to have very elevated blood sugar... It's about keeping things as level as possible and a non-invasive monitoring path can help a lot...

I was very low carb (fewer than 30g/day) for over a year, and was still hospitalized for ketoacidosis.
