Forbes Health Calorie Calculator

The Forbes Health Calorie Calculator helps you determine your daily calorie needs based on your age, gender, weight, height, and activity level. This tool provides an estimate of the number of calories you should consume each day to maintain your current weight or achieve specific health goals.

How to Use This Calculator

Using the Forbes Health Calorie Calculator is simple. Follow these steps:

Enter your age in years.
Select your gender (male or female).
Enter your weight in pounds or kilograms.
Enter your height in inches or centimeters.
Select your activity level from the dropdown menu.
Click the "Calculate" button to get your results.

The calculator will provide your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE), which are key indicators of your daily calorie needs.

The Formula Explained

The Forbes Health Calorie Calculator uses the Mifflin-St Jeor equation to estimate your daily calorie needs. The formula is as follows:

For men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5

For women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

Where TDEE = BMR × activity factor

The activity factors are:

Sedentary (little or no exercise): 1.2
Lightly active (light exercise/sports 1-3 days/week): 1.375
Moderately active (moderate exercise/sports 3-5 days/week): 1.55
Very active (hard exercise/sports 6-7 days a week): 1.725
Extra active (very hard exercise/sports & physical job): 1.9

These formulas provide an estimate of your daily calorie needs based on your physical characteristics and activity level.

Interpreting Your Results

Your results will include two key numbers:

Basal Metabolic Rate (BMR): The number of calories your body needs to perform basic functions at rest.
Total Daily Energy Expenditure (TDEE): The total number of calories your body needs to maintain your current weight, accounting for your activity level.

To lose weight, you should consume fewer calories than your TDEE. To gain weight, you should consume more calories than your TDEE. The exact number of calories you need to consume to achieve your weight loss or gain goals will depend on your specific goals and the advice of a healthcare professional.

Worked Example

Let's calculate the daily calorie needs for a 30-year-old woman who weighs 150 pounds (68 kg), is 5'5" (165 cm) tall, and is moderately active.

Convert weight to kilograms: 150 lbs × 0.453592 = 68 kg
Calculate BMR: (10 × 68) + (6.25 × 165) - (5 × 30) - 161 = 680 + 1031.25 - 150 - 161 = 1400.25 kcal
Calculate TDEE: 1400.25 × 1.55 = 2170.375 kcal

This woman's daily calorie needs are approximately 2170 kcal. To lose weight, she should consume fewer than 2170 kcal per day. To maintain her current weight, she should consume around 2170 kcal per day. To gain weight, she should consume more than 2170 kcal per day.
