CMV: Promoting body positivity (obesity) is no different from promoting drug use or anorexia.

I understand it exists to make obese people feel more included, but when it's used by ad companies to promote products. I think it's dangerous as it ignores how unhealthy obesity scientifically is. 

I should add that I don't think fat shaming is right either, as that probably doesn't fix the issue. But body positivity is very harmful to society as obese people are led to believe that it's not as unhealthy as it is in reality. 

Japan has created a law wherein employees between the ages of 40 to 75 have to get their waists measured to ensure they aren't overweight. If the waist size target isn't hit, the company would get fined. I'm oversimplying it since I haven't researched the metabo law in depth, but I believe that's the gist of it. 
I think ideas like that are fantastic and actually benefit society greatly.

Shaming people with anorexia and drug abuse makes it much less likely for those groups to make positive changes in their lives. 

In general, the best way to change human behavior is through rewards. Punishments make people avoid the source of punishment more than the behavior the punishment targets. For instance: more we shame people for being over weight, the more over weight people are going to stay indoors. Similarly, thinking you can make a poor student study harder by telling them they are stupid will be counter productive.

As any psychologist can tell you, people with self esteem make better lifestyle choices. This is just universally true.
