A Heavy Burden: the individual costs of being overweight and obese in the USA

This is an interesting research report on some key financial costs of being overweight and obese. A summary is presented below:

More than 60% of the United States population is overweight or obese, and if the current trajectory continues, 50% of the population will be obese by 2030. There is no question that being obese or overweight, is more costly than being of normal weight. Using existing literature, we have detailed the costs incurred due to overweight and obesity that affect working-age adults at the individual level.

What is the cost of being obese in America?
The overall, tangible, annual costs of being obese are $4,879 for an obese woman and $2,646 for an obese man. The overall annual costs of being overweight are $524 and $432 for women and men, respectively. For both genders, the incremental costs of obesity are much higher than the incremental costs of being overweight.

Adding the value of lost life to these annual costs produces even more dramatic results. Average annualized costs, including value of lost life, are $8,365 for obese women and $6,518 for obese men.
We only have a partial approximation of the cost of obesity for individuals.

The picture we have created is only a partial look at the individual costs related to obesity. Existing literature provides information on health- and work-related costs, but with the exception of fuel costs, there is no published academic research that gives us insight into consumer-related costs, such as clothing, air travel, automobile size or furniture. Anecdotal evidence suggests these costs could be significant.
How obese you are matters.

Where it was possible to break down the costs by degrees of obesity, it is clear the incremental costs of morbid obesity are much higher than those of moderate obesity. Total incremental costs for obese women are more than nine times higher than those for overweight women. For obese men, the incremental costs are six times higher than for overweight men.

The cost drivers are different for the overweight and the obese.

  • For those who are overweight, the main cost drivers are direct medical costs – 66% for women and 80% for men. 
  • Conversely, while direct medical cost is the primary driver of costs for obese men, only one-third of the overall costs for obese women are medical costs.
  • Obese women are disproportionately affected by job-related costs.
  • The overall, annual, incremental costs are significantly higher for obese women than for obese men. The difference is mostly the result of lost wages for obese women.
