The difference between actual and desired body weight is a stronger predictor of health than body mass index (BMI).

In a secondary analysis of the 2003 Behavioral Risk Factor Surveillance System (BRFSS) data set, researchers looked at a sample of 150,577 participants to examine the impact of desired body weight, independent of actual BMI, on the number of physically and mentally unhealthy days subjects report over one month. After controlling for BMI and age, researchers found that men who wished to lose 1 percent, 10 percent and 20 percent of their body weight, respectively, reported 0.1, 0.9 and 2.7 more unhealthy days per month than those who were happy with their weight. Among women, the corresponding increase in numbers of reported unhealthy days was 0.1, 1.6 and 4.3. Additionally, the desire to lose weight was more predictive of unhealthy days among women than among men, and among whites than among blacks or Hispanics.

"Our preliminary data suggest that some of the obesity epidemic may be partially attributable to social constructs that surround ideal body types," the study's authors said.
