How do you factor in the overabundance of cheap, nutritionally fucked food, and how that may affect those living paycheck to paycheck?

I eat constantly processed shit. I hate cooking, but it's still damn simple, don't get the biggest meal at McDonald's, get the low sodium/fat frozen pre cooked meals that only have a couple hundred calories per serving for under the cost of a meal from fast food. Then you just don't over eat, wait 20mins or so after and let your body naturally tell you it's full instead of eating until you want to puke. Bottled water is cheaper than cans or soda regardless of if you get them from a dollar store or not. It's literally cheaper to eat less food which is the main part of weight maintenance.

Side note, as a nurse I've seen patients who are obese because of circumstances and medical issues. Someone who has to work two jobs, has a kid, and newly discovered hypothyroidism is not obese because they don't care. They have a medical issue and no extra time/resources to compensate for it with a refined diet and exercise (especially considering one of the most common symptoms of hypothyroidism is fatigue). You're not even factoring in the undiagnosed, or those who don't have access to sufficient healthcare.

Hypothyroidism is like 5% of the population. Obesity is at 40%, let's not act like our obesity epidemic is because everyone with hypothyroidism is trying to move to the USA to boost our statistics.

My overall point is if you're targeting obese people specifically, you're not on the right track.

Na there is nuance between shaming someone for decisions made well within their control and understanding some are placed there beyond their control. I'm not advocating for those with hypothyroidism to be attacked, if anything calling out obesity would help bring awareness to those fronts as it would promote discussion about the issues instead of downplaying it so those with issues cant get the help needed like you descibed earlier in your post. Like trying to pass legislation that requires employers to give reasonable medical accommodations to those individuals so they have enough time to prep meals or even have subsidies that can give them more healthy choices at reasonable prices.
