The problem is obesity. Obesity is not genetic, it's not a disease, and it's not caused by the type of work you do, your race, environment or age. It's caused by taking in more calories than you burn. Take a walk in any mall in America, along an ocean beach, down a school hallway, anywhere many people gather and you can see the problem. Burn more calories than you take in and you're not obese. It's that simple. This is not rocket meizitang advanced plus science.
There may be a few exceptions; people with some other physical disorder that contributes to their being obese. It should be understood that this exception is very, very, rare. The vast majority of overweight or obese people are this way as a result of their own poor 2 day diet review choices.
Talk Show hosts have had people come on and describe themselves as fat and happy. They are comfortable with themselves, with who they are. Many people watch this and it's the excuse they need to continue doing nothing. This is not the message to send.
