Key Takeaways

Choose IIFYM if tracking calorie and macronutrient targets is practical and psychologically comfortable.
Treat Clean Eating as a food-quality framework, not proof that calorie balance is irrelevant.
Measure actual adherence, food quality, fiber intake, and personal response rather than relying on unsupported outcome averages.
Consider a hybrid of macro awareness and mostly nutrient-dense foods as a practical synthesis, not a separately studied diet outcome.
