The debate over the association between dietary patterns and obesity has not been settled in the literature. Some studies suggest that there are significant differences in mean body mass index across dietary patterns whereas other studies refute that result. The objective of this study is to test whether dietary patterns have a significant effect on body mass index in Korean adults when controlling for calorie intake and several sociodemographic factors. We present new evidence derived from pseudo panel data created from a series of cross‐sections. Our results from the pseudo panel analysis show that some of the dietary patterns that were identified from the Korean adults’ food intake survey have a significant effect on body mass index. Specifically, males with the “beef and processed food” (P < 0.05), or “pork and alcohol” (P < 0.05) dietary pattern had significantly higher BMIs, whereas females with the “fast food” (P < 0.1) or “ramen and bakery” (P < 0.01) dietary pattern had higher BMI.
