Notes. BMI = body mass index; NS = not significant. Only groups for which the association between percentage of desired weight loss and physically or mentally unhealthy days was statistically significant (P < .05) are shown. None of the between-group differences were significantly different. Model 1 (n = 137 132) was controlled for age and BMI. Model 2 (n = 136 734) was controlled for age, BMI, education, and smoking.

^aPercentage of desired weight loss was calculated as [(actual weight – desired weight)/actual weight] ×100%.
