The only way this post would even remotely make sense, is if we were in the, let's say, late 1800s or early 1900s, when many people were, indeed, malnourished. I am given to understand that when drafting troops for the First World War, many men were found to be underweight. We don't have that problem anymore.
I am old enough to remember when it was unusual for anyone to be obese. Fast-forward to today, a random walk through any Walmart on a Saturday afternoon will turn up at least a dozen people who would have been considered freaks fifty years ago.
