“A fast-food company like McDonald’s may not be responsible for the entire obesity epidemic,” Banzhaf says. “But let's say they’re 5 percent responsible. Five percent of $117 billion is still an enormous amount of money.”

“…in the middle of a killer epidemic is it really a good idea to have three fast-food joints within a half a block of a high school? There is no reason we can’t, through zoning and planning, regulate the location, density, or hours of junk-food outlets…”

“[T]hat figure is by no means well established. Not only is it derived from weak or incomplete data, but it is also called into question by the methodologic difficulties of determining which of the many factors contribute to premature death.”

“Our model assumes that coronary heart-disease, hypertension, and diabetes occur independently. However, we know that there is some interdependence among these disease states, especially in obese patients. Thus, calculating the cost of obesity as it related to these diseases independently would inflate the cost estimate.”

“Overweight may or may not be due to increases in body fat. It may also be due to an increase in lean muscle. For example, professional athletes may be very lean and muscular, with very little body fat, yet they may weigh more than others of the same height. While they may qualify as ‘overweight’ due to their large muscle mass, they are not necessarily ‘over fat,’ regardless of BMI.”

“Two people can have the same BMI, but a different percent body fat. A bodybuilder with a large muscle mass and a low percent body fat may have the same BMI as a person who has more body fat because BMI is calculated using weight and height only.”
