I’ve been a type 1 diabetic for 12 years and a director at a kids camp for type 1 diabetics for 5 years. There is no such thing as a “diabetic attack”. There is high blood sugar (because diabetics either don’t make or don’t process insulin) and there is low blood sugar (because an insulin dependent diabetic took too much insulin). What you are trying to describe is a diabetic seizure which 99% of the time is an accidental overdose of insulin (low blood sugar).
Now if you’re trying to talk about complications from uncontrolled diabetes from a lifetime of not taking care of it yes that is terrible, but that’s the minority of diabetics and you have to go to pretty extreme lengths of not taking care of it (literally years/decades) to get to that point, so let’s not act like the issue is the diabetes itself.
And even if we ignore all that what the fuck does that have to do with eating meat? Most diabetics prefer a high protein diet because it’s CARBS that raise blood sugar. If you’re argument is meat = fat = overweight then 2 things, overweight doesn’t cause diabetes (it’s a factor for type 2 only), and 2: the issue still isn’t the diabetes, it’s the complete lack of caring for a medical issue.
