Rationale: Sarcopenia represents a critical challenge to healthy aging, with nutrition emerging as a key modifiable factor that may contribute to its development. We aimed to compare the dietary composition between sarcopenic and non- sarcopenic Arab men.

Methods: This community-based cross-sectional study included 432 Arab men aged 46.80 ± 15.93 years, 154 of whom were sarcopenic. Body composition was assessed using a multi-frequency bioelectrical impedance. Muscle strength was measured using a handgrip test. Dietary intake was evaluated using a validated food frequency questionnaire. Comparisons between sarcopenic and non- sarcopenic groups were made using the independent samples t-test.

Results: Sarcopenic men showed significantly lower body mass index (25.70±3.79 kg/m²), fat mass (19.69±8.24 kg), muscle mass (48.23±5.82 kg), fat mass index (7.20±3.08) and fat free mass index (17.51±1.77) compared with non-sarcopenic men (body mass index: 30.16±4.96 kg/m²; fat mass: 24.98±10.02 kg; muscle mass: 58.92±6.38kg; fat mass index: 8.70±3.52; fat free mass index: 20.42±1.80). Sarcopenic men also showed significantly lower total energy intake (2223.82±604.42 kcal/day), protein intake (124.63 ± 89.79 g/day), fat intake (59.74±   27.77 g/day), percentage of energy from protein (21.11±   10.06%), percentage of energy from fat (24.44±9.79%) and higher percentage of energy from carbohydrates (54.46 ± 10.78%) than non-sarcopenic men (total energy intake:  2392.94±717.80 kcal/day; protein intake: 150.10±112.14 g/day; fat intake: 69.64±33.53 g/day, protein energy%: 23.58±11.58 %; fat energy%:  26.58±10.09%; carbohydrates energy%: 49.80±11.49 %).

Conclusion: Sarcopenic men exhibited differences in both energy intake and dietary composition compared with nonsarcopenic men. These findings underscore the critical role of nutrition in the development and management of sarcopenia, as well as in promoting healthy aging.
