I have no problem with someone being comfortable in their own skin, and even showing it off in a bathing suit if they want.
My problem is the promotion of being overweight without the slightest bit of concern for your health. If there is any one area of research that has the most scientific literature backing it, its the relationship between being overweight and health problems. The amount of studies showing this correlation is staggering.
Then you will hear many overweight people say, "yes I am overweight, but I am healthy." I am no nutritionist or fitness expert, but I am assuming its very difficult to be overweight and healthy at the same time. How does one achieve this?
Though the above model is nowhere near obese so perhaps she is still healthy? Can you be her size and still be healthy?
