Harris Benedict Equation Calculator
Calculate how many calories to consume in a day to sustain current
weight and metabolism with this Harris Benedict Equation Calorie Intake Calculator.
Enter your Basal Metabolic Rate (Females / Males) and the activity level
multiplier that best matches your lifestyle.
Activity Level Multiplier:
1.200 = Sedentary Lifestyle (very little exercise)
1.375 = Lightly Active Lifestyle (exercise 1-3 days/week)
1.550 = Moderately Active Lifestyle (exercise 3-5 days/week)

To determine the amount of calories needed to sustain your current
weight and metabolism use this calorie per day formula:
Calories/Day = BMR x Activity Multiplier
Example: For a body with a BMR of 1605 and an exercise level of
Calories/Day = 1605 x 1.550
This gives an answer of 2,488 calories/day needed to meet current body
