Health
BMR & Daily Calorie Needs Calculator
Calculate Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then multiply by an activity factor to estimate Total Daily Energy Expenditure (TDEE) — the calories you burn in a typical day. Use it as the baseline for weight management, sports nutrition, and meal planning.

Fitness
Protein Intake Calculator
Estimate daily protein need (grams) from body weight, training intensity, and goal (maintain, build, or lose weight). Targets evidence-based ranges for active people: 1.2–2.2 g protein per kg body weight depending on activity and objective.
