Application of a Sports Nutrition Protocol in "Non-Athlete" ojects aimed at Body Recomposition: An Observational Study

Abstract

Introduction: Non-athletic individuals with low physical activity and high fat mass may benefit from structured nutritional plans. This study evaluated the effectiveness of an athlete- based nutritional protocol (e.g., high protein intake) in improving body composition reducing fat mass while preserving lean mass in non-athletes performing mild physical activity. Methods: Fifty-seven subjects (mean age 34.5 ± 15.87 years) engaged in mild "Fitness" activity (3 sessions/week) were assessed before (T0) and after (T1) at least 3 months of nutritional intervention, using multi-frequency BIA (InBody 320). Results: After 3 months, participants showed significant reductions in body weight (p<0.001) and fat mass (p<0.001), with maintenance or increases in lean mass (p<0.001). Improvements were also observed in blood biomarkers, metabolic syndrome risk, and basal metabolic rate, supporting long- term result stability. Conclusions: An athlete-oriented nutritional protocol was effective in improving body composition and health markers in non-athletic individuals with mild activity levels, even over a short period.
