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.

To get this percentage, divide calories from fat by total calories (this information appears on the food label) and then multiply by 100. For example, if a 300-calorie food has 60 calories from fat, you divide 60 by 300 and then multiply by 100. That food has 20% of its calories from fat.

There are 9 calories in a gram of fat, so divide the number of calories by 9. Divide 400 calories by 9 to get 44 grams. Then divide 700 calories by 9 to get 78 grams.

Each gram of protein contains four calories. Simply divide the two calorie range numbers by four. A man who eats 2,000 calories per day should consume 200 to 700 calories from protein or 50 to 175 grams of protein.

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.

Old Program. With the old program, point totals were figured by calories and adjusted up or down based on the total fat and fiber in food. Under this program, 25 points approximated 1,250 calories, assuming the fiber and fat in the food basically offset each other in the formula.

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. If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725.

To calculate this, divide a food or drink's calories from fat by total calories (this information is on the product's food label) and then multiply by 100. For example, if a 300-calorie food has 60 calories from fat, divide 60 by 300 and then multiply by 100.

Here's the formula. Assuming it takes 10 calories per pound to maintain your weight, take your weight and multiply it by 10. For example, if you weigh 150 pounds, then your caloric allowance is 1,500 calories (150 x 10 = 1,500).

Just take your current weight and multiply it by 13 (if you don't exercise at all), 15 (if you exercise a few times weekly) or 18 (if you exercise five days or more a week). The number you'll be left with is a rough idea of how many calories you're most likely eating right now.

TO RECAP, HERE'S HOW TO EAT TO BUILD MUSCLE: Calculate your TDEE (Total Daily Energy Expenditure) and add 250 calories over your number. Consume 1-1.5g per pound (2.2-3.3g per kg) of bodyweight in protein every day. Consume the rest of your calories from foods composed of carbs and fats.
