![]() Other factors that can be considered in the calculation include the thermic effect of food, though this is not always factored into the calculation, and has a relatively smaller impact than BMR and activity level. ![]() Once BMR is calculated, it is typically multiplied by an activity level factor, which is based on factors such as exercise and whether a person has a sedentary or very active job. They are generally pretty similar, but the Katch-McArdle Formula, for example, which takes metabolic activity (resulting from differences between lean body mass and body fat) into account, can be more accurate for lean persons. Some of the more commonly used equations for estimating BMR include the Mifflin St-Jeor Equation, Harris-Benedict equation, and Katch-McArdle Formula. This includes physical characteristics such as age, gender, height, and weight. The calculation usually begins with an estimation of basal metabolic rate (BMR), which is based on the use of equations that have been developed for this specific purpose. TDEE is calculated based on the factors described above. Protein, for example, has a far larger thermic effect than dietary fat, since it is more difficult to process. It is sometimes estimated as 10% of food energy intake, but this can vary significantly depending on the type of food consumed. The thermic effect of food, also referred to as specific dynamic action, is the amount of energy required by the body to process and use food. These factors are more specifically referred to as the thermic effect of activity, and non-exercise activity thermogenesis (energy expended for non-sleeping, eating, or sports-like exercise). This includes deliberate exercise as well as other activities that a person may undergo as part of their job or typical daily activities. In other words, it is the minimum energy needed to maintain a person's vital organs only.Īctivity level is a factor that is based on the amount of activity a person undergoes. More often, it is estimated using factors such as a person's basal metabolic rate (BMR), activity level, and the thermic effect of food.īMR is a person's energy usage rate while at rest in a temperate environment when the digestive system is inactive. TDEE is hard to measure accurately and varies day by day. It is the total energy that a person uses in a day. TDEE stands for total daily energy expenditure.

This should be accomplished by having a caloric-dense diet with regular exercise. Estimated daily calorie needs Recommended intakes of macronutrients, water, vitamins, and minerals based on DRI data. Lastly, if you wish to gain weight, you need to consume more calories than you burn. ![]() Keep in mind that leaner bodies need more calories than less lean bodies. If you wish to burn more calories over consuming fewer, you should increase your physical activity – you can consume more calories and still sustain weight loss as long as you eat fewer calories than calculated. ![]() If you wish to consume less throughout your day, you will want to eat 500-1,000 fewer calories per day than calculated, or as an alternative, eat 15-20% fewer calories than calculated. ![]() Conversely, if you want to lose weight, this can be accomplished by consuming less calories or burning more calories. In order to maintain your current weight, you must consume the same number of calories as you burn. Using the calculator above will help you determine your specific daily caloric needs.

Everyone requires different amounts of energy per day depending on their age, size, and activity levels. This maintenance calorie calculator will allow you to calculate the calories your body needs in order to maintain your current weight. Generally, a calorie refers to energy consumption through food and beverage consumption and the amount of energy usage spent through physical activity. ![]()
