Some of the people certainly making the fun of overweight people and make them feel ashamed of their weight and eating habits.
People also try to force them to get lesser food and more exercise with this belief that they will look better.

It’s very shameful and disgust behaviour of our society that this society makes fun of them instead of appreciating which leads to some harmful effects. This includes depression, low self-esteem, eating disorders and negativity thinking. Thus, we all should appreciate them to be healthy and chubby instead of making fun and help to grow our society happy and healthy one.
