Why do fat people expect us to feel bad for them?

sorry but i dont feel bad for fat people unless the weight issue is hereditary but if the person is perfectly fine but keeps eating and eating and gains 20 pounds in a week its their fault. and i dont think eating is the culprit for weight gain its the types of foods that you eat and how much you eat it. compare a person who eats loads of meat,veggies,rice,yogurts to a person who eats loads of cheese burgers,hot dogs,pop tarts and sweets , so why people think eating less will solve the problem. theres no problem eating junk food but eat it in moderation. its what you eat and how active you are
