## Summary

The JISSN position stand by Aragon AA et al. from 2017 provides evidence-based nutritional recommendations for optimal body composition and was published in the Journal of the International Society of Sports Nutrition.

Study Background

This position stand analyzes various diet approaches (low-carb, high-protein, intermittent fasting) for fat loss and muscle preservation in athletes.

Main Findings

The position stand shows: - Protein intake: 1.6-2.2 g/kg during calorie deficit for muscle preservation - Calorie deficit: Moderate deficit (300-500 kcal) better than aggressive - Carbohydrates: At least 3-5 g/kg for resistance training, more for endurance - Fats: At least 0.5-1.5 g/kg for hormonal function - Flexibility: No superior diet method (low-carb vs. high-carb)

Methodology

Position stand is based on meta-analyses and systematic reviews of diet interventions in athletes.
