Objectives: This study evaluated the association between restricted carbohydrate diets and prevalent cardiometabolic disease (CMD), stratified by fat intake.

Methods: Dietary and CMD data were obtained from 19,078 participants ≥20 y in the National Health and Nutrition Examination Survey (NHANES) 1999-2018. The National Cancer Institute (NCI) methodology was used to assess usual intake of foods and nutrients.

Results: Compared to individuals that met all macronutrient recommendations, those consuming restricted carbohydrate diets ( < 45%en) were 1.123 (95% CI 1.113-1.133) times as likely to have CMD, and those consuming the recommended amount of carbohydrates only were 1.060 (1.058-1.062) times as likely to have CMD. Higher intakes of saturated and polyunsaturated fat were associated with greater prevalence of CMD in restricted and recommended carbohydrate intake groups. Higher intakes of monounsaturated fat were associated with lower prevalence of CMD among participants that met carbohydrate recommendations only.

Conclusions: Participants that consumed restricted carbohydrate diets were more likely to have CMD compared to participants that met all macronutrient recommendations, and this association was modified by fat intake. Greater efforts are needed to understand longitudinal associations between carbohydrate intake and CMD.
