Blaze Nutrition Calculator Formula
The calculation relies on the standard formula derived from the Metabolic Equivalent of Task (MET) concept. This formula relates the energy cost of an activity to your body weight and the duration of the activity.
Calories Burned (kcal) = Duration (min) × (MET × Weight (kg) × 3.5) / 200
C = D × (M × W × 3.5) / 200

Variables Explained
- Activity Duration (D): The total time spent performing the exercise, measured in minutes.
- Body Weight (W): Your weight in kilograms (kg). The calculator requires kg for the standard METs formula.
- Activity MET Value (M): The Metabolic Equivalent of Task, a measure of the energy cost of physical activity (e.g., 3.5 for walking, 8.0 for running).
- Calories Burned (C): The resulting energy expenditure, measured in kilocalories (kcal).

What is Blaze Nutrition?
The “Blaze Nutrition” concept emphasizes high-intensity, efficient energy expenditure and subsequent nutrient timing to maximize fitness results. Calculating the calories burned (the ‘blaze’) is the foundational step. The METs formula allows fitness enthusiasts and athletes to quantify the intensity of their workouts regardless of the specific activity.
A high MET value indicates a greater caloric burn per minute, which is key to achieving aggressive weight loss or fitness conditioning goals. By knowing the precise energy output, users can match their nutritional intake to their energy needs, ensuring they fuel their body correctly for recovery and muscle building while maintaining a caloric deficit for fat loss.
How to Calculate Calories Burned (Example)
- Identify Variables: A person weighs 80 kg, runs for 45 minutes, and running has a MET value of 8.0.
- Plug into Formula: $C = 45 \times (8.0 \times 80 \times 3.5) / 200$.
- Calculate Numerator: $8.0 \times 80 \times 3.5 = 2240$.
- Simplify Fraction: $2240 / 200 = 11.2$. This is the Calorie Burn per minute.
- Calculate Total Calories: $C = 45 \times 11.2 = 504$ kcal.
Frequently Asked Questions (FAQ)
Is the Blaze Nutrition Calculator highly accurate?
The calculator provides a strong estimate based on the scientifically validated METs formula. Accuracy is highest when using an accurate MET value for your specific activity and an up-to-date weight measurement. Individual metabolic rates can cause minor variations.
Why do I need to enter Weight in kg?
The standard METs formula, derived from physiological studies, uses kilograms for body weight. While you can convert lbs to kg (1 lb ≈ 0.453592 kg) before input, using kg directly ensures the most consistent and direct application of the formula.
What is a MET value?
MET stands for Metabolic Equivalent of Task. 1 MET is the rate of energy expenditure while sitting quietly. An activity with a MET of 5 means you are exerting five times the energy as you would at rest. Higher METs mean higher intensity and more calories burned.
Can I use this to solve for my needed MET value?
Yes. If you know your Weight, Duration, and a Calories Burned target, the calculator will solve for the required MET value (intensity) you need to hit that goal.
