Forbes Health TDEE Calculator Free

Calculating your Total Daily Energy Expenditure (TDEE) is essential for understanding your calorie needs and achieving your health goals. This Forbes Health TDEE calculator provides an accurate estimate based on your age, weight, height, gender, and activity level.

What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day. It includes:

Basal Metabolic Rate (BMR) - calories burned at rest
Calories burned through physical activity
Thermic Effect of Food (TEF) - calories burned digesting food

Knowing your TDEE helps you determine how many calories you need to maintain, lose, or gain weight. The Forbes Health TDEE formula is one of the most accurate methods available, incorporating both BMR and activity level calculations.

How to Use This Calculator

Enter your age in years
Select your gender (male or female)
Enter your weight in pounds
Enter your height in inches
Select your activity level from the dropdown
Click "Calculate" to see your TDEE

For best results, measure your weight and height accurately. If you're between activity levels, choose the one that most closely matches your typical routine.

Formula Used

The Forbes Health TDEE calculator uses the following formula:

TDEE = (BMR × Activity Factor) + TEF BMR = (Weight × 10) + (Height × 6.25) - (Age × 5) + Gender Adjustment TEF = 10% of BMR

The gender adjustment is +5 for males and -161 for females. The activity factors are:

Sedentary: 1.2
Lightly active: 1.375
Moderately active: 1.55
Very active: 1.725
Extremely active: 1.9

Interpreting Your Results

Your TDEE result shows the total calories your body needs each day to maintain your current weight. Here's what the different activity levels mean:

Activity Level	Description	Example
Sedentary	Little to no exercise	Desk job with no exercise
Lightly active	Light exercise 1-3 days/week	Walking 30 minutes daily
Moderately active	Moderate exercise 3-5 days/week	Jogging 30 minutes 3 times/week
Very active	Hard exercise 6-7 days/week	Running 60 minutes 5 times/week
Extremely active	Very hard exercise daily	Athlete training 2 hours/day

To lose weight, subtract 250-500 calories from your TDEE. To gain weight, add 250-500 calories. Always consult a healthcare professional before making significant changes to your diet or exercise routine.
