Macronutrients, or "macros," are the three main nutrients your body needs in large amounts: Protein, Carbohydrates, and Fat. Each provides energy (calories) and serves unique functions in the body.
The ratios (e.g., 40/30/30) represent the percentage of your total daily calories that should come from Carbohydrates, Protein, and Fat, respectively. Different diet plans recommend different ratios to achieve specific health or fitness goals.
This calculator provides an estimate for informational purposes. Individual needs can vary greatly. For a personalized nutrition plan, please consult with a registered dietitian or healthcare professional.
