2. Journal • What are calories? • Are calories good or bad? Explain. • (Put your snacks under your desk…we will get to them in a bit.)

3. Calories are in any food that contains carbohydrates, proteins or fats. Calories measure the amount of energy or heat is in a food. A calorie is a unit of heat or energy. We need to eat 2000-3000 calories a day. Pg. 98

4. What do you mean calories have heat? 100 calories (medium apple or 2 regular Oreo cookies) is enough to boil an entire quart of water. So how many quarts of water would you be able to boil in a day? (Hint: How many calories do we need a day?) 20-30 quarts of water

5. So why don’t calories make our blood boil? Digestion and metabolism tap off energy in small amounts to power the body and some of the heat is used to actually keep us warm.

6. What is caloric intake? Caloric intake = amount of food/calories we eat What is caloric expenditure? Caloric expenditure = amount of calories we use Pg. 98

7. Carbohydrates and proteins store the least amount of energy (calories), while fats store the most. Carbohydrates = 4 calories per gram Proteins = 4 calories per gram Fats = 9 calories per gram One pound of body fat = 3500 calories. Pg. 98
