I love how you, like so many who do your writing in the interests of the obese, absolutely NEVER EVER, cite a single study in support of your "concern."
FYI: I weigh in at a socially acceptable BMI, my blood pressure is great, I eat pounds of vegetables each day, but depsite all of this behavior that fatphobes deem worthy, I don't think it's my job to police the bodies of others.
If you really "cared," about the body obese, you could write about the role of big sugar or industrial agriculture or the increased weight of the granddaughters whose grandfathers smoked before the age of 13.
Or you could focus on making safer more walkable communities, restoring recess and PE to schools, or advocate for a living wage and a shorter work week so ALL people had time to execise.
But no, like so many tiresome articles before yours, you focus on the behavior of individuals instead of the policies that lead to the general increase in weight.
If you think the junk food they eat is so awful, then take Richard Nixon and his Secretary of Agriculture, Earl Butz, to task for all that they did to make this moment in history possible.
