To use this tool, scientists place the food in question in a sealed container surrounded by water and heat it until the food is completely burned off. Scientists then record the rise in water temperature to determine the number of calories in the product. But bomb calorimeters aren't the only way to measure calories.

If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375. If you are moderately active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55.

Calories. Let's take an example. If your food item contained 10 grams of protein, 10 grams of fat and 10 grams of carbs, then 40 calories would be from protein, 40 calories from carbs and there would be 90 calories from fat for a total of 170 calories.

To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows: If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2. If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.
