It was revised in 1984 to be more accurate and was used up until 1990, when the Mifflin-St Jeor Equation was introduced. The Harris-Benedict Equation was one of the earliest equations used to calculate basal metabolic rate (BMR), which is the amount of energy expended per day at rest.

The following converter can be used to convert between Calories and other common food energy units. Very intense exercise: 2+ hours of elevated heart rate activity.Intense exercise: 45-120 minutes of elevated heart rate activity.Exercise: 15-30 minutes of elevated heart rate activity.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.

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.

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.

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)
