I'm T2D - I've come to believe obesity is a side effect of diabetes, if I'm not on my medications, I can fast for 2-3 days before my blood sugar comes down, because my liver is constantly pumping out glucose into my system.

There is no doubt that hyper processed foods make this condition more likely, but its not just "you have weak willpower and got fat and sick" - I know a ton of fat people who do not have and will likely will never develop T2D.
