I have known some stocky runners. They are a distinct minority.
Fat runners are rare.
That is because running while fat is very hard on your feet, knees, hips and shin bones. In other words fat people who choose running as their primary aerobics exercise typically injure themselves before they get much benefit from running.
You leave the finish line too soon, they're usually found at the back of the pack........
Ever notice there are no elderly fat people?
We’re reaching peak stupidity on this stuff. Medicine has its fads and even not a little quackery every now and then in terms of diet and nutrition, but one thing they have nailed down is the link between obesity and diabetes, heart disease and other ailments. It is astonishing to see pushback on this, sex changes for children, and the rest of it.
Spend some time at buffet restaurants, and watch as a new party comes into the place to sit down.
