TDEE Calculator: Calculate Your Total Daily Energy Expenditure (2024)

FAQs

How to calculate daily energy expenditure? ›

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.

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)

In numbers, the calorie estimations should be within ~10% IF you are honest about your activity level. If someone needs about 2,300 calories per day, the calculator could be off by 230ish calories. Over the course of 1 month, this is equal to ~7,000 calories (2lbs).

Your TDEE represents the number of calories required to maintain your current weight. To lose weight, you typically aim for a calorie intake that's 10-20% lower than your TDEE. This ensures a gradual and sustainable rate of weight loss, generally recommended at about 0.5 to 1 kilogram (1 to 2 pounds) per week.

Rizzo's is not the only 2-2-2 method — Dr. Ian Smith created a 2-2-2 metabolism plan that involves eating carb-heavy, protein-filled meals for two weeks and then alternating between keto and carb-loading for four weeks.

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. The TDEE requires you to include your activity level - and that activity can be anything that requires you to move around.

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 10000 Steps Equal To? “But,” continues Jamie, “if you walk briskly for 30 minutes and include enough activity throughout the day to reach the combined total of 10,000 steps, you're burning about 400 to 500 calories a day, which means you're losing one pound each week.”

Total daily energy expenditure (TDEE) declines with weight loss due to decreases in both resting energy expenditure (REE) and physical activity energy expenditure (PAEE) that result primarily from the reduction in body mass (1).

How do I calculate my resting energy expenditure? ›

The Mifflin-St Jeor equation, created in the 1990s, provided an alternative and more valid estimate of RMR (3). 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.

Your total daily energy expenditure (TDEE) is the number of calories you burn throughout a 24-hour period. These calories come from the work your body does to keep you alive, including your brain functions, breathing, digestion, and so on as well as all of your physical activity.

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.

That calorie blaze might resemble a five-alarm fire at certain times of the day, like when you're exercising, but the flame is always lit. Over the course of a day, your body's natural calorie burn without any activity can range from 1,300 to more than 2,000, depending on your age and sex.

Whenever there are notable changes to body weight. Not every fluctuation in weight means that figures should be recalculated, but significant changes of 5-10% will likely influence TDEE.

TDEE is calculated by adding four numbers together: basal metabolic rate, thermic effect of feeding, exercise energy expenditure, and non-exercise activity thermogenesis.

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.

Energy expenditure can be estimated by measuring macronutrient or oxygen consumption, or heat production or carbon dioxide production. Most measurement approaches in use today involve the measurement of oxygen consumption and/or production of carbon dioxide via indirect calorimetry.
