Calculating TDEE requires multiplying your BMR, derived from the Mifflin-St Jeor equation, by an activity multiplier based on your daily movement. You must input accurate biometrics including age, weight, height, gender, and activity level to determine total daily energy expenditure correctly.

Calculating BMR and TDEE accurately requires your age, gender, weight, height, and daily activity level. These biometrics feed into the Mifflin-St Jeor formula to establish baseline metabolic rate before applying activity multipliers for total energy expenditure.

Yes, you can set macronutrient targets for maintenance by inferring a maintenance goal from your context. The calculation uses your TDEE to balance calories and macros, maintaining your current weight rather than applying a deficit or surplus for weight loss or muscle gain.

Calculating nutritional needs does not work accurately without knowing your daily activity level. Activity multipliers are required to scale your BMR into a TDEE value; without this input, calorie and macronutrient targets for weight loss or muscle gain cannot be precisely determined.

The Mifflin-St Jeor formula calculates BMR using modern biometric averages, providing a more accurate basal metabolic rate than older equations. It scales effectively with weight changes, making it highly reliable for setting baseline calories before applying activity multipliers.
