Daily energy expenditure formula & calculator for men and women? ›

The Mifflin St. Jeor equation is written as follows: For men: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5 (kcal / day) For women: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) -161 (kcal / day)

Calculating TDEE using the formula TDEE = BMR x Activity Factor involves two steps: Step 1: Calculate your BMR using the following formula. So your BMR is 1536.25 calories per day. Step 2: Multiply your BMR by your activity factor to calculate your TDEE.

There are several equations you can use to calculate your TDEE, but the Forbes Health TDEE Calculator uses the Mifflin-St Jeor equation because experts from the American Council on Exercise (ACE) consider it to be the most accurate.

The equations for males and females are: Men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5. Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161.

To use a TDEE calculator, you typically input information such as your age, gender, weight, height, and activity level. The calculator then estimates your Total Daily Energy Expenditure (TDEE). To lose weight, aim for a calorie intake lower than your TDEE while monitoring your progress and adjusting as needed.

Energy expenditure (calories/minute) = . 0175 x MET (from chart) x weight (in kilograms) (To find out your weight in kilograms, simply divide your weight in pounds by 2.2.) the same time period.

TDEE includes all forms of activity. That activity can be exercise in the form of workouts at the gym, yoga, pilates, or running. That activity can also be walking, cleaning, or playing with your kids in the park.

Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and is, therefore, what we used in this calculator. This BMR formula is as follows: BMR (kcal/day) = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (y) + s (kcal/day) , where s is +5 for males and -161 for females.

BMR is a component of your TDEE, but it is NOT the amount of calories you should eat to lose weight. BMR is the amount of calories your body needs to "keep the lights on" and ensure you live to fight another day. To lose weight, you need to eat about 15-20% less than your TDEE.

What is the best calculator for weight loss? ›

Everyday Health's weight loss calculator, developed by registered dietitian-nutritionists (RDNs) and the team at Lose It!, provides personalized daily calorie goals. The calculator suggests minimum daily calorie intakes of 1,200 for women, 1,350 for nonbinary individuals, and 1,500 for men.

A much more accurate method for determining TDEE is to determine your basal metabolic rate (BMR) using multiple factors, including height, weight, age, and sex, then multiply the BMR by an activity factor to calculate TDEE.

Of these equations, the Mifflin-St Jeor Equation is considered the most accurate equation for calculating BMR with the exception that the Katch-McArdle Formula can be more accurate for people who are leaner and know their body fat percentage.

FAQ #1: What is the best calorie calculator? If you don't know your body fat percentage, the Mifflin-St Jeor calorie calculator equation tends to produce the most accurate results. If you know your body fat percentage, the Katch-McArdle equation is the most accurate.

On the other hand, a Total Daily Energy Expenditure (TDEE) calculator estimates the total calories you burn in a day, including your basal metabolic rate and physical activity. While a calorie counter focuses on intake, a TDEE calculator provides a broader picture of your energy needs.

Daily energy expenditure consists of four components: 1) sleeping metabolic rate, 2) the energy cost of arousal, 3) the thermic effect of food (or diet-induced energy expenditure (DEE)), and 4) the energy cost of physical activity or activity-induced energy expenditure (AEE).

There is no standard for the number of calories you should expend during a day. Many factors are involved, including body size, age, gender, and most importantly your level of physical activity. The average daily energy expenditure is 3000 kcal for men and 2100 kcal for women between the ages of 19 and 22 years.

E = P*(t/1000); where E = energy measured in Joules or kilowatt-hours (kWh), P = power units in watts, and t = time over which the power or energy was consumed.

Multiplying the PAL by the BMR gives the actual energy requirements. For example, a male with a PAL of 1.75 and a mean BMR of 7.10 MJ/day (1 697 kcal/day) would have a mean energy requirement of 1.75 × 7.10 = 12.42 MJ/day (2 970 kcal/day).
