Analyzes macronutrient distribution for healthy eating. This tool calculates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation and your Total Daily Energy Expenditure (TDEE) based on your activity level. From there, it determines your daily caloric needs based on your fitness goal (weight maintenance, loss, or gain) and provides a detailed breakdown of macronutrients (protein, carbohydrates, and fat) in both grams and percentages, visualized with a responsive chart.
