Adopted by: ACSM, Academy of Nutrition and Dietetics, International Society of Sports Nutrition (ISSN) Impact: ISSN position stand (2017) confirms protein at 1.6–2.2g/kg/day maximizes muscle protein synthesis; Helms' meta-analysis shows caloric precision within ±10% of TDEE is the primary determinant of body composition change.
Why best: Macronutrient targets provide a structured nutritional framework that prevents the most common failure modes: inadequate protein (muscle loss during deficit), insufficient calories (performance decline), and excess fat or carbohydrate (suboptimal partitioning). A macro-first approach ensures both performance and body composition goals are served simultaneously.
80kg male, fat loss goal, TDEE = 3,000 kcal: Caloric target = 3,000 × 0.80 = 2,400 kcal. Protein = 80 × 2.0 = 160g = 640 kcal. Fat = 80 × 0.7 = 56g = 504 kcal. Carbs = (2,400 − 640 − 504) / 4 = 314g. Macro split: 160P / 314C / 56F at 2,400 kcal.
