4. Healthy looks different on different people.
There are extreme ends of emaciation and overweight that carry health risks, but guess what? That's between those people and their health care providers. It's not up for public opinion. The issue here is that as a society, we have a mental image of what "healthy" is and it's a fairly narrow window. Thinness doesn't automatically equal health, and extra weight doesn't automatically equal health problems. There is a wide range of normal, and the images we see in the media often don't reflect that.
