What is the Harris Benedict equation used to calculate?

basal metabolic rate (BMR)
The Harris Benedict equation is a calorie formula using the variables of height, weight, age, and gender to calculate basal metabolic rate (BMR). This is more accurate than calculating calorie needs based on total body weight alone.

What is the formula for calculating calories in food?

To calculate food calories, start by looking at how much protein, carbohydrates, and fat the food has. Then, multiply the total number of grams of protein by 4, since 1 gram of protein is equal to 4 calories. Do the same thing for the carbohydrates, since 1 gram of carbohydrates is equal to 4 calories.

How do I calculate my caloric intake to lose weight?

For example, if you weigh 165 pounds and exercise three days a week, then you would multiply 165 by 15 for a total of 2,475. That means your daily calorie intake—and how you will stay stuck at your current weight—is about 2,475 calories.

What is the Henry equation for BMR?

Calculating the Harris-Benedict BMR

Men BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
Women BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161

Which calorie equation is most accurate?

Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and, is therefore what we used in this calculator. This BMR formula is as follows: BMR (kcal / day) = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (y) + s (kcal / day) , where s is +5 for males and -161 for females.

What is the weight loss formula?

The following formula determines percentage of weight loss: (Starting weight minus current weight) / (starting weight) x 100 equals % of body weight loss. If current weight is less than 5% of usual body weight, the weight change is considered not significant.
