How many calories you burn in a day depends on several factors that are out of your control. Be sure to consult a healthcare provider or a registered dietitian, though, before you make changes to your diet and exercise plans. An individuals total daily energy expenditure is the sum of all the different processes: Thermal effect of exercise: (TEE): energy required for exercise or physical activity. expenditure = time spent in each activity (min) x (multiplied by) If you feel like you are sitting more and moving less, you may be looking for simple ways to burn more energy.

Most techniques will have conversion tables available. In the direct method for the measurement of energy expenditure for individuals, the Atwater calorimeter is used which consists of a chamber in which a person could live and work for several days allowing at the same time the measurement of his total output of heat. Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA). You also can increase your daily energy expenditure by making a conscious effort to add more movement into your day.

Indirect calorimetry (IC) is the gold standard for measuring resting energy expenditure (REE), this study aimed to compare the results of REE estimated by different methods with those obtained by IC for patients with pulmonary hypertension. This is a very accurate method of measuring energy expenditure. Several methods are available to determine the total daily energy expenditure (TEE), and these include measurements such as whole body indirect calorimetry ( Shetty et al, 1987 ), which.
