Basal Metabolic Rate (BMR) Click here to calculate your basal (resting) metabolic rate To determine your total daily calorie needs, multiply your BMR by the appropriate activity factor, as follows (Harris-Benedict Equation): 1.  If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2 2.  If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375 3.  If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55 4.  If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725 5.  If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9   Ideal Body Weight and Body Mass Index Click here to calculate your ideal body weight and your body mass index My Pyramid Food Calorie Chart Click here to access a chart containing the calorie content of various foods I Eat 33,000 Calories Per Day   Below are two people from The Learning Channel's I Eat 33,000 per day.  The average human will eat between 2,000 and 3,000 calories per day.  These people eat nearly 10 times that amount.
