Association between low-carbohydrate diet and low-fat diet scores and sarcopenia as determined by dual-energy X-ray absorptiometry: a cross-sectional study

In this cross-sectional study, higher overall and healthful LCD scores are associated with a lower risk of sarcopenia, whereas higher overall and unhealthful LFD scores are associated with an increased risk. These findings suggest that the relationships between LCD, LFD, and sarcopenia may depend not only on the quantity of macronutrients but also on their dietary sources.
