America's Obesity Crisis:Are You Responsible for Your Own Weight?

To counter criticism, the food industry and pro-business groups use a public relations script focused on personal responsibility. The script has three elements: 1) if people are overweight, it is their own fault; 2) industry responds to consumer demand but does not create it; and 3) insisting that industry change--say, by not marketing to children or requiring restaurants to reveal calories--is an attack on freedom.

Why quarrel with the personal-responsibility argument?

First, it's wrong. The prevalence of obesity increases year after year. Were people less responsible in 2002 than in 2001? Obesity is a global problem. Is irresponsibility an epidemic around the world?

Second, it ignores biology. Humans are hardwired, as a survival strategy, to like foods high in sugar, fat and calories.

Third, the argument is not helpful. Imploring people to eat better and exercise more has been the default approach to obesity for years. That is a failed experiment.

Fourth, personal responsibility is a trap. The argument is startlingly similar to the tobacco industry's efforts to stave off legislative and regulatory interventions. The nation tolerated personal-responsibility arguments from Big Tobacco for decades, with disastrous results.

Governments collude with industry when they shift attention from conditions promoting poor diets to the individuals who consume them. Government should be doing everything it can to create conditions that lead to healthy eating, support parents in raising healthy children and make decisions in the interests of public health rather than private profit.
