While researching a story I learned that many obese people are actually metabolically healthy, and many people who appear to be a "normal" weight are not. You truly cannot tell by looking at someone which one they are. WebMD says this:

"Many overweight and obese Americans might be perfectly healthy when it comes to blood pressure, cholesterol and blood sugar levels -- while many thin folks may not be the picture of good health, a new study contends.

Using a government health survey, researchers found that nearly half of overweight U.S. adults were "metabolically healthy." That meant they had no more than one risk factor for type 2 diabetes and heart disease -- including high blood pressure, unhealthy cholesterol or triglyceride levels, elevated blood sugar, or high concentrations of C-reactive protein (a marker of inflammation in the blood vessels).

Among obese adults, 29 percent were deemed healthy -- as were 16 percent of those who were severely obese based on body mass index (BMI, a ratio of weight to height). On the other hand, more than 30 percent of normal-weight Americans were metabolically unhealthy."

On the other hand, empathy and kindness never hurt anyone. As someone who routinely dismantles erroneous cultural narratives, I applaud your continued efforts to do so on this subject and wish you all the best.

The guy who says he can't care about you because there are children living in cardboard boxes needs to get his head (or possibly his heart) examined.
