![]() ![]() This is also true during exercise since the body has to do more work to provide energy to a larger person than it would to a smaller person. A person who is larger due to more muscle, fat, or height burns more calories. The MET of various tasks have been widely studied, and our calculator estimates calories burned based on data made available through these studies.Ī person's body mass affects how many calories they burn, even at rest. Most estimates (including the ones provided by our calculator) involve the use of three key factors: body mass, duration of the activity, and the metabolic equivalent of a task (MET). The number of calories a person burns by performing a given activity is dependent on many different factors. For more information about basal metabolic rate, refer to our BMR calculator. Generally, the number of calories consumed, less calories burned through activities and basal metabolic rate (calories consumed - calories burned - BMR) will determine whether a person maintains, loses, or gains weight theoretically, if the number is 0, the person will maintain their weight if the number is negative, they will lose weight if the number is positive, they will gain weight. ![]() The formula and methodology used by this calculator are described below in the "Calculating calories burned" section.įor more information on the number of calories a person should consume each day for weight maintenance, weight loss, or weight gain, refer to the Calorie calculator. The results of this calculator (and any other) are based on standardized data that references an "average" person, so it is only an estimate. Remember, combining exercise with a small calorie deficit is the best intervention to maximize weight loss! Additionally, consuming a high protein diet (or sticking to the higher ranges based on your activity level) will help maintain and preserve muscle mass while losing fat.The number of calories that the body burns during regular daily activities or exercise is dependent on various factors, so it is not an exact science. Therefore, creating a calorie deficit of 500-1,000 calories per day can lead to a max weight loss rate of 2lbs/week. Taking this into consideration, it is more feasible to cut back on food since daily caloric requirements for maintaining weight are much higher. So keeping that in mind, the goal is to lose 1-2lbs per week.įor sedentary individuals, it would be recommended to set a goal of losing 1lb per week, which would equate to a calorie deficit of 500 calories/day.įor more active individuals, daily calorie requirements are higher in order to account for exercise and active lifestyles. More often than not, when weight loss exceeds 2lbs in a week, the majority of that is water loss. That would equate to a calorie deficit of 1,000 calories per day. See this blog on How Many Carbs Per Day for Weight Loss to learn more.įor healthy, sustainable weight loss, it is generally not advisable to lose more than 2 pounds of fat per week. Step 2: Divide answers in step 1 by 4 since there are 4 calories per 1 gram of carbohydrate Multiply daily calorie requirements by 0.45 & 0.65 to obtain calories from carbohydrates. Step 1: Calculating grams of carbohydrates. The Dietary Guidelines for Americans recommends that carbohydrates should make up 45-65% of one’s daily calories. ![]() Third: Calculate Daily Carbohydrate needs ![]() See this blog on How Much Fat Per Day for Weight Loss to learn more. Using both of these references you can calculate your daily fat needs: The Dietary Guidelines for Americans also recommends fat should make up 20-35% of one’s total daily calories. To prevent any fatty acid deficiencies it is recommended to consume at minimum 1g/kg of fat per day. Multiply weight in kilograms by range that best fits your activity levels. This is the last step of calculating calories, and it's one that's absolutely essential for getting accurate weight loss results.ĭid you know that protein is a huge catalyst for weight loss and hunger satiation? Let's compare and contrasts sedentary versus moderately active individuals and their protein requirements.įor sedentary/lightly active individuals: 1-1.2g/kg/dayįor moderately active - extremely active: 1.4-2.2g/kg/dayĬonvert body weight in pounds to kg’s (round to the nearest 10th) ![]()
