![]() It reflects the minimum energy needed to sustain metabolic processes that keep you alive. Your Body's Energy Expenditure Components BMR (Basal Metabolic Rate)īasal metabolic rate (BMR) is your body's energy expenditure rate when digestion of food and physical activity has minimal influence on your metabolism. Carbohydrates and proteins release about 4 kcal of energy per gram, while fat releases about 9 kcal per gram. The three macronutrients that supply your body with energy from food are carbohydrates, protein, and fat. The body releases chemical bonds in the foods you eat through oxidization to get the needed energy. ![]() Energy is also required to transport, synthesize and replace molecules that makeup body tissue. Your body constantly burns energy to support its autonomic systems, such as breathing, the nervous system, circulation, body temperature regulation, and physical activities. Eating less than your TDEE will lead to weight loss while consuming more than your TDEE will result in weight gain. It quantifies the calories needed to maintain your weight. 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.Total Daily Energy Expenditure (TDEE) refers to the total energy your body expends in a day. 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.

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) ![]()
