Health
BMR & TDEE Calculator
Calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) using the Mifflin–St Jeor equation. Essential for setting accurate calorie targets when losing, gaining, or maintaining weight.

Health
Ideal Weight Calculator
Estimate your "ideal" reference body weight from your height, biological sex, and body frame size using the Devine formula — originally created in 1974 for pharmacological dose calculation and still used clinically today. Useful as a rough planning anchor, but not a personal weight goal: it ignores muscle mass, age, and individual physiology.
