It was sad and they know full well what they are doing to themselves but they are addicted to food. It is an addiction like any other except you can't avoid food. We have to eat. Most of us love food and we overeat or have overeaten , that's why we are here, right? But most of us are not addicted to food as we can control what we eat and stop when we are full and make wise choices for the food we buy and eat.
The saddest was the young man who almost died. He had been there for ages, a year or so? and had not lost a single pound because he refused to follow the healthy eating plan. What else did he have in his life except for food? Just laying in bed, not working , looking after a family , socialising, all the normal things. I'm not even sure how his insurance allows him to stay there
