This tool calculates the calories you need daily to train like Iron Man based on your physical activity and body parameters.
How to Use the Iron Man Calorie Calculator
Enter your age, select your gender, input your weight in kilograms, height in centimeters, and choose your activity level. Click the “Calculate” button to see your daily calorie needs based on your Basal Metabolic Rate (BMR) and activity level.
How It Calculates the Results
The calorie calculator uses the Mifflin-St Jeor Equation to estimate the number of calories you need per day:
- For males: BMR = (10 * weight) + (6.25 * height) – (5 * age) + 5
- For females: BMR = (10 * weight) + (6.25 * height) – (5 * age) – 161
The BMR is then multiplied by the selected activity factor to get your total daily energy expenditure (TDEE).
Limitations
This calculator provides an estimate based on standard equations and does not account for all variables such as muscle mass, fat distribution, or metabolic adaptations. For personalized dietary advice, consult a healthcare provider or a registered dietitian.
