Yes, being fat is your fault. It's not only your fault, but living in a post-indsutrial society does not absolve you from the fact that you're using your body the wrong way. Not only is it evident that your physical activity is pitiful, it's also showing that you have little criteria in what you ingest. You don't need to eat out everytime. Cook at home and take lunch to work it there's no healthy place near you. Oh, it takes time and effort? Well, it's better that time and effort than the persitent damage your organs and bones are suffering from being forced through overweight. Also, if you're going to throw out the biological argument for fat storage, you can't just forget your body was also made to move. I'm not saying anyone should try to look like models, with zero fat deposits (and all their metabolic disorders that carries), but it is everyone's duty -yes, I use that word, duty- to keep their own body within healthy boundries of weight. If you are now overweight, my question always is: why didn't you stop before you got to this point? If you're here, being complacent with your obesity and asking everyone to not offend your sensibilities won't bring you back to a healthy body. If I sound callous, so be it. More often than not, it's poor habits and terrible discipline and education that make people obese, not some genetic disorder that couldn't be avoided.
