A weighty issue—Can you tell if you’re fat or slim? Don’t rely on your perception. A study of more than 2000 young women in Texas found that 23% of overweight (BMI > 25) participants believed themselves to be a healthy weight. Overweight African-American women were more likely to mistakenly perceive themselves as slim compared with their white counterparts (odds ratio 2.84; 95% confidence interval 1.79 to 4.50), as were women without a college education. Overweight women who could not correctly identify themselves as fat were less likely to attempt weight loss through diet and exercise.
