Assuming that America's 227 million adults are an average of 20 pounds overweight, that means that they consume how many extra calories per year altogether?
It may seem excessive, but the fact is that one trillion calories is actually a weak estimate of how much unnecessary intake is going on. Taken altogether, America's adults consume an appalling 16 trillion extra calories annually, the equivalent of 14 billion Big Mac extra value meals.
