Should you go on a diet if your kneecaps have double chins?

Should you go on a diet if your kneecaps have double chins? NO.

How do people get so disgustingly fat? Sitting on their butts watching daytime TV and filling mouths with garbage.

Since weight creeps on, the person who is gaining weight doesn't generally notice the increase until it becomes a problem. Coupled with depression, other health and mobility problems, genetics, lifestyle and food choices, and social conditioning, it is easy to see how people become overweight and then find it almost impossible to lose it.

Perhaps instead of focusing on other people's weight, which is none of your business, you might want to give some thought to your own prejudices and need to demean other people.

ps I am guessing that ol Bill is trying to "help" people. Calling them disgusting isn't too helpful. But no, it isn't really his business either.

I don't think they realize it. Also, if someone is in a depression, sometimes food is what he/she uses to try to feel better. Another factor could be cost. Lean meats and fresh produce are a lot more expensive than fatty meats, sugar filled canned fruit, and canned/frozen vegetables. Also, if someone is really poor, he/she probably tries to fill up on cheap stuff like pasta and rice.

By that point I would think that you are past the point of no return.
