I see little problem in people being fat.. every thing I consume I pay for from my wage and I enjoy eating and drinking. I would not want to jog up the high street and eat salad for 50 years hoping to be healthy and then get dementia or cancer etc. I'll do what I enjoy now knowing life will be a bit shorter but happier due to the enjoyment I get from food.. In my eyes its no worse than cig, pot or alcohol.
If you want to be thin it's portion control and exercise. I'm not bothered for either tbh..
