Protein Calculator

The Protein Calculator helps users estimate their daily protein needs based on body weight, activity level, and fitness goals (e.g., maintenance, muscle gain, fat loss). It uses evidence-based guidelines (e.g., 1.2–2.2 g/kg body weight) and provides personalized recommendations with visual feedback. Ideal for athletes, fitness enthusiasts, or anyone tracking macronutrients.
