Macro Nutrient Calculator

How Does the Macro Nutrient Calculator Work?

The Macro Nutrient Calculator helps you understand how your daily needs for protein, carbohydrates, and fats are determined based on your age, gender, weight, height, activity level, and fitness goals. By entering your details, you can learn how these factors influence your nutritional requirements and how to balance your diet for different objectives such as maintenance, muscle gain, or weight loss.

The calculator uses evidence-based formulas to estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE), then applies macro ratios tailored to your goal. Adjust your macros as your weight or activity level changes for best results.
