3. We all know how to read how many calories are in a product, but where do they come from? »Caloric Breakdown 1 g Carbohydrates: 4 calories 1 g Protein: 4 calories 1 g Fat: 9 calories 1 g Alcohol: 7 calories http://home.howstuffworks.com/calorie.htm

4. In order to determine how many calories are needed for our body to function, three factors are taken into account: 3 factors in determining caloric needs: 1.- BMR- Basal Metabolic Rate 2.- Physical Activity 3.- Thermic Effect of Food

5. BMR- Basal Metabolic Rate the amount of energy your body needs to function at rest Harris-Benedict formula Adult male: 66 + (6.3 x body weight in lbs.) + (12.9 x height in inches) - (6.8 x age in years) Adult female: 655 + (4.3 x weight in lbs.) + (4.7 x height in inches) - (4.7 x age in years) http://home.howstuffworks.com/calorie.htm

6. Physical Activity This includes practically everything done during the day, for example: Activity (1 hour) 130 lbs155 lbs190 lbs Aerobics (general)354 cal422 cal518 cal Billiards148 cal176 cal216 cal Ultimate Frisbee207 cal246 cal302 cal Jumping Rope (general)590 cal704 cal863 cal Running (9 min. mile)649 cal774 cal949 cal Soccer (general)413 cal493 cal604 cal Walking (3 m.p.h.)207 cal246 cal302 cal

7. Thermic Effect of Food how much energy your body uses to digest food To calculate: multiply the total number of calories you consume in one day by.10, or 10% http://home.howstuffworks.com/calorie.htm

8. To put calories in perspective:

9. Still want to eat that fast food? A quarter pounder hamburger contains about 420 calories. A quarter pounder with large fries & large shake contains about 1200 calories. A quarter pounder with cheese, large fries & large shake contains about 1300 calories. To burn off the calories in the latter, take a brisk 5 hour walk. A better option than a quarter pounder is a regular hamburger with regular fries. This contains about 475 calories. You can walk off the calories in this, in less than 2 hours. http://www.annecollins.com/calories/calories-quarter-pounder.htm

So a soda with 100 calories really has 100,000 calories, but have no fear, this also applies to calories burned.
