Estimating Total Daily Energy Expenditure

TDEE is also a useful predictor for your daily water intake requirements. Age is also a factor, with older individuals expending less energy than individuals of the same weight and gender of a younger age as you will note if you enter a different age in our online total daily energy expenditure calculator.ĭaily energy expenditure estimates are used in a variety of clinical settings as well as sports / fitness activities. For example, women tend to have a higher percentage of body fat and smaller muscle mass, resulting in lower energy expenditure relative to their weight. Hot climate can increase your TDEE by 5-20%, but cold climate can have similar effects due to shivering and increased metabolism to maintain core temperature.īody size and body composition both play a role in your TDEE and this is reflected in the output of our calculator. It's range is between 10-13% of the energy provided by the food. Your diet comes in at second place due to the thermic effect of food on total energy expenditure. Of the three, the most profound is the effect of physical activity - usually between 15 - 30% of TDEE. For women pregnancy is also a factor as it increases the energy cost of physical activities. There are three main things that affect it: physical activity, dietary-induced thermogenesis, and the climate you spend your day in. TDEE stands for Total Daily Energy Expenditure and it is a measure of how much energy in Calories or kilocalories (kcal) you expend during your day and this is exactly what our TDEE calculator helps you estimate. We recommend you use our calorie calculator for weight loss for a much more precise estimate. A single asterisk (*) accompanies the calorie intake estimation denoting that this is a rough guideline. TDEE metrics used: 1 Calorie = 1 kcal (1 kilocalorie) = 1,000 calories. Estimating Total Daily Energy Expenditure.It is also important to make sure you have measured your calories correctly. The Thermic Effect of Food (TEF) measures the calories we burn in the digesting of food.Īs the TDEE given by this website is just an estimate, you should weigh yourself regularly if you are dieting. Such as walking to work or climbing the stairs in your home. EAT typically refers to purposeful exercise such as going for a run or lifting weights, whilst NEAT would include activities Both refer toĮnergy burned by using your body and being active. 'Non-Exercise Activity Thermogenesis' and 'Exercise Activity Thermogenesis' respectively. The exact formulas used by this calculator to calculate BMR, and the other components of TDEE, are explained below. Measuring BMR officially must be done in a laboratory, but this calculatorĬan give an accurate estimate.

If you eat more calories than your TDEE, you will gain weight. If you eat less calories than your TDEE, you will lose weight.

If you eat calories equal to your TDEE, you will maintain the same weight. Its biggest component is Basal Metabolic Rate (BMR) - the amount of calories burned at rest. Total Daily Energy Expenditure (TDEE) is a measure for the total amount of calories the human body burns through in a day.
