Estimate basal metabolic rate using the Katch-McArdle formula based on body weight and body fat percentage, then adjust by activity level to estimate daily calorie needs.

Estimate daily calorie needs using the Harris-Benedict equation based on sex, age, weight, height, and activity level. The result shows total daily energy expenditure calories needed to maintain current weight.

Estimate daily calorie needs using the Mifflin-St Jeor equation with sex, age, weight, height, and activity level. The result gives estimated maintenance calories per day.

Estimate resting metabolic rate (RMR) using the Mifflin-St Jeor equation, adjusted for sex. Enter age, weight, height, and sex to calculate the calories your body burns at rest each day.

Estimate total daily energy expenditure (TDEE) from your basal metabolic rate (BMR) using activity level, exercise sessions, and goal adjustment.

Estimate daily calorie needs for weight loss using basal metabolic rate, activity level, and a calorie deficit. Uses the Mifflin-St Jeor equation to estimate BMR, then calculates maintenance calories and target calories for fat loss.

Calculate basal metabolic rate for men using the Mifflin-St Jeor equation based on age, weight, height, and unit system.

Estimate basal metabolic rate for women using age, height, weight, and formula selection. BMR represents the calories your body needs at rest to maintain basic functions.

Estimate your basal metabolic rate (BMR), the number of calories your body burns at rest each day, using the Mifflin-St Jeor equation with inputs for sex, age, weight, and height.

Estimate your basal metabolic rate (BMR), the number of calories your body needs each day at rest, using the Mifflin-St Jeor equation with inputs for sex, age, weight, and height.

Estimate total daily energy expenditure for active adults using the Mifflin-St Jeor BMR equation adjusted by activity level. Enter age, sex, weight, height, and training activity to estimate daily calorie needs.

Estimate total daily energy expenditure for a sedentary lifestyle using age, sex, weight, and height. This calculator uses the Mifflin-St Jeor BMR equation and applies a sedentary activity multiplier of 1.2.

Estimate total daily energy expenditure using the Katch-McArdle formula based on weight, body fat percentage, age, and activity level.

Estimate daily calories for muscle gain using age, sex, body weight, height, activity level, and training surplus. The calculator estimates BMR with the Mifflin-St Jeor equation, applies an activity multiplier to find TDEE, then adds a calorie surplus to support lean muscle gain.

Estimate your daily calorie target for weight loss using age, sex, weight, height, activity level, and desired weekly weight loss. This calculator estimates BMR with the Mifflin-St Jeor equation, applies an activity multiplier to find TDEE, then subtracts the calories needed to support your target rate of weight loss.

Estimate total daily energy expenditure for men using the Mifflin-St Jeor equation and an activity multiplier.

Estimate total daily energy expenditure for women using age, weight, height, and activity level. Uses the Mifflin-St Jeor equation for women to calculate BMR, then applies an activity multiplier to estimate daily calorie needs.

Estimate your total daily energy expenditure (TDEE) using the Mifflin-St Jeor equation for basal metabolic rate and an activity multiplier.

Estimate Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor equation adjusted by activity level.

Estimate the daily calorie deficit and number of days needed to lose 1 kilogram of body weight based on your planned calorie reduction and added exercise. Uses the common estimate that losing 1 kg requires a total deficit of about 7,700 calories.

Estimate the daily calorie deficit needed to lose one pound over your chosen time frame, based on the common guideline that one pound of body fat is approximately 3,500 calories.

Estimate your weekly calorie deficit based on daily maintenance calories, daily calorie intake, exercise calories burned, and number of workout days per week.

Estimate a daily calorie goal based on age, sex, weight, height, activity level, and goal pace using the Mifflin-St Jeor equation with activity and calorie adjustment factors.

Estimate your average daily calorie target and high-, medium-, and low-calorie days for a calorie cycling plan based on body weight, maintenance calories, weekly training days, and goal.

Estimate your daily cutting calories based on body weight, height, age, sex, activity level, and desired calorie deficit. Uses the Mifflin-St Jeor equation to estimate maintenance calories and then applies a cutting deficit.

Estimate daily calories for a bulking phase using body weight, height, age, sex, activity level, and desired calorie surplus. The calculation uses the Mifflin-St Jeor equation for BMR, then applies an activity multiplier and adds a bulking surplus.

Estimate daily calories needed to gain weight based on sex, age, weight, height, activity level, and desired weekly weight gain. Uses Mifflin-St Jeor BMR and adds a calorie surplus for weight gain.

Estimate your daily calorie target for gaining weight by adding a calorie surplus to your maintenance calories based on body weight, age, sex, activity level, and desired weekly weight gain.

Estimate your daily calorie target for weight loss using age, sex, weight, height, activity level, and desired weekly weight loss. This calculator uses the Mifflin-St Jeor equation to estimate basal metabolic rate, adjusts for activity, and subtracts calories based on your target rate of weight loss.

Estimate daily calorie intake for weight loss using age, sex, weight, height, activity level, and desired weekly weight loss. The calculation uses the Mifflin-St Jeor equation for BMR, adjusts for activity, then subtracts a calorie deficit based on target weekly weight loss.
