I have a couple of points to make on what has come up here and in the Covid thread.
First, I don't think obesity is always the result of laziness or that it's a choice, even when a person has no underlying physical cause of their obesity. Imagine a single mother who works two jobs. She doesn't have time (or child care) to go to the store often and when she does she needs to make her money stretch. So she buys shelf stable, highly processed foods. She can't afford a gym or exercise equipment. She again doesn't have child care to go jogging and the area she lives isn't safe enough for that anyway. She's overweight but she doesn't have a whole lot of ability to eat right and exercise not to mention she doesn't have much knowledge on how to get into shape and little in the way of instruction.
That happens more than people think.
Next, I think there's a feeling that choosing things over exercise is always a bad choice. Before Covid hit, I was working at a job that required a long commute. The earliest I would get home is 7:30. I had a choice. I could go have a workout or I could spend time with my infant son. During the first 3 years of my son's life I put on 30 pounds. I don't regret that choice at all. I don't act like it was the healthy choice, but it was the right choice.
