Find your ideal macronutrient split for flexible dieting.
If It Fits Your Macros (IIFYM) is a flexible dieting approach that focuses on hitting daily macronutrient targets rather than restricting food choices. TDEE is calculated using the Mifflin-St Jeor equation, then protein is set at 2 g/kg, fat at 25% of calories, and the remainder goes to carbs. Adjust ratios based on personal preference and sport demands.
