Understanding Nutrition Calculation
What Are Macronutrients?
Macronutrients (macros) are the three main nutrients your body needs in large amounts: protein, carbohydrates, and fats. Each provides energy (calories) and serves essential functions in your body.
Why Track Nutrition?
Tracking nutrition helps you understand what you're eating, meet fitness goals, manage weight, and ensure you're getting balanced nutrition. It's essential for meal planning, recipe development, and dietary management.
How Calorie Calculation Works
This calculator uses the Atwater system: protein and carbohydrates provide 4 calories per gram, while fat provides 9 calories per gram. Total calories = (protein × 4) + (carbs × 4) + (fat × 9).
Tips for Accurate Tracking
Use food labels for packaged items, reference USDA FoodData Central for whole foods, weigh ingredients for precision, and remember that cooking methods can affect nutrient content slightly.
