Objectives: Obesity has increased in the Asian population where it is typically a low fat diet and shows lower body mass index (BMI). This study aimed to investigate the relationship of dietary carbohydrate or dietary fat intake with percent body fat as well as BMI.

Methods: A total of 16,156 adults (6,594 men and 9,562 women) aged 19 years or more who had participated in the 24-h dietary recall survey and the dual-energy X-ray absorptiometry (DEXA) measurement were included from the 2008-2011 Korea National Health and Nutrition Examination Survey of data. Obesity was defined using BMI (>25 kg/) according to the criteria of Korean Society for the Study of Obesity or percentage of total body fat (>25% in men, >35% in women) according to the criteria of World Health Organization.

Results: The prevalence of obesity by BMI was 36.4% in men and, 27.4% in women, while that by percent body fat was 29.8% in men and, 36.6% in women. After adjusting for confounding variables, the prevalence of obesity defined using BMI showed no significant associations with the quintiles of dietary carbohydrate or fat intake in both men and women. On the other hand, people in the highest quintile of carbohydrate intake showed reduced risks of obesity by percentage of total body fat (OR 0.64, 95% CI 0.51-0.80), but those of fat intake showed increased risks (OR 1.46, 95% CI 1.17-1.84) only in women.

Conclusions: Dietary carbohydrate or fat intake shows stronger associations with body fat rather than BMI.
