What is the best way to start a sustainable type 2 diabetes management routine?

[Kyle.L]

My father was recently diagnosed with type 2 diabetes, and he's feeling pretty overwhelmed by all the new information. The doctor gave him a pamphlet and talked about medications, but the day-to-day reality is what's tripping him up. He's confused about how to interpret the numbers on his new glucose monitor, and he's worried about what he can actually eat beyond just "avoiding sugar." I'm trying to help him find clear, practical resources, but there's so much conflicting advice out there. I think he needs a better understanding of the holistic picture of Diabetes management, one that connects the dots between monitoring, diet, medication, and even exercise in a way that doesn't feel like a constant, stressful test. Where do people usually start when building a sustainable routine?
