Daily Caloric Requirement for an Individual
In the pursuit of maintaining a healthy weight, understanding your daily calorie needs is crucial. Here's a simplified guide to help you estimate your caloric intake, using the Harris-Benedict formula.
- Calculate BMR using the Harris-Benedict equation
For men, the equation is:
For women, the equation is:
- Adjust for physical activity by multiplying BMR by an activity factor (to get TDEE)
Your activity level plays a significant role in your daily calorie burn. Here's a table to help you determine the correct multiplier:
| Activity Level | Multiplier | |-------------------------|------------| | Sedentary (little or no exercise) | 1.2 | | Lightly active (1-3 days/week) | 1.375 | | Moderately active (3-5 days/week) | 1.55 | | Very active (6-7 days/week) | 1.725 | | Extremely active (very hard daily exercise or physical job) | 1.9 |
So,
- Include the Thermic Effect of Food (TEF)
TEF represents the energy expended on digesting food, generally about 10% of calories consumed. Therefore, adjust by adding roughly 10% of TDEE:
Putting it together:
This gives a comprehensive estimate of daily calories needed to maintain your weight including basal metabolism, activity, and digestion energy costs[1][2][4][5].
Remember, the "percent daily values" on food labels are based on a 2,000 calorie diet. For more information about beer and alcohol calories, please refer to the related resources provided in the next page.
The Harris-Benedict formula is one of the most accurate methods for estimating BMR. Height, weight, gender, age, and activity level all affect a person's caloric needs. There are separate calculators for males and females available. Keep in mind that the number of calories consumed by a person in a day may vary.

- To determine your Basal Metabolic Rate (BMR), utilize the provided Harris-Benedict equation, with equations specific for men and women.
- Analyze your physical activity level, and multiply your BMR by the appropriate multiplier from the provided table to acquire your Total Daily Energy Expenditure (TDEE).
- To account for the Thermic Effect of Food (TEF), add around 10% of TDEE to your total.
- By considering BMR, activity level, and TEF, you can estimate the calories needed to maintain your current weight in the context of health-and-wellness, fitness-and-exercise, nutrition, and weight-management.
