On the one end, some people do have a hard time or maybe even actually impossible time to fight their obesity.
On the other end, a lot of people are dismissive of trying to lose weight and hide behind “body positivity” and “obese people can’t help it” when they could really get a lot of results if they actually took it seriously. A relative of mine has been obese for decades, even as the diabetes came on the general take away they had was “apply medicine, keep living how I like”. Then when their liver started failing due to the fat and got the prognosis that they were probably going to die in a matter of months, they found the motivation to lose 40 pounds, in the goal of extending their life a little. Now they have what is, by all appearances, a healthy liver again. They also have much better mobility, reduced joint pain, blood sugar that doesn’t need medication anymore. Though they are still stuck with a lot of the damage already done, losing weight has been a great boon to their life, and something they always had dismissed as being something other people could do but they were just stuck that way.
