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

ABSTRACT:

Objective

This study aimed to investigate the effects of low-carbohydrate diets (LCD) and low-fat diets (LFD) on sarcopenia, as well as the source and quality of nutrients, to provide strong support for the development of a more scientifically based dietary guidance scheme.

Methods

The data of this study came from the National Health and Nutrition Examination Survey (NHANES). LCD and LFD scores were calculated based on macronutrient energy proportions. Logistic regression, isoenergetic substitution models were used to evaluate associations with sarcopenia, defined by dual-energy X-ray absorptiometry (DXA).

Results

A total of 1,745 participants were included in this study, with a mean age of 38.71 ± 0.46 years and a mean body mass index (BMI) of 28.87 ± 0.26 kg/m². Aft
