Id say its not the lack of empathy that you feel, but maybe the non trivial effort to normalize morbid obesity that is met with hostility.

We should not celebrate morbid obesity as normal and beautiful.

We gain nothing from villanizing people that suffer from it either.

I personally have never suffered obesity but as the years go on, my body seems to want to put a ludicrous amount of fat in places it never used to. I maintain muscle mass by regular resistance training mixed with cardio and HIIT and that helps a lot with the otherwize natural loss of muscle over 40. Personally this is where excercise definetly helps me.

Also now at 50, I dont have insulin resistance or high blood pressure as many of my fellow 50 year olds are falling prey to.

Even the healthy weight 50 year olds around me are starting blood pressure medication. This is where I beleive the excercise regime I follow has worked wonders. Not so much for weight loss as many seem to think.

It gets harder every year though to maintain physique and low body fat.

Excercise has tremendous benefits for your health and looks but for great weight loss is a matter of nutrition and what particular combo suits your body, economy and culture.
