1. Define calories and explain how the body gets energy .a unit equal to the kilocalorie, used to express the heat output of an organism and the fuel or energy value of food.

2. What are your total calories in and total calories out?


3. According to your total calories in and out, will you gain weight, lose weight or maintain your weight over time? Why? If you will gain or lose weight, how long will it take you to gain or lose one pound of body fat?


4. Let's say you start jogging every day, burning an additional 300 calories a day. At this rate, how long would it take you to lose one pound of body fat?


5. Let's say you start drinking a soda from the school vending machine every day, taking in an additional 200 calories a day. At this rate, how long would it take you to gain one pound of body fat?

Answer 1

1. Calories become energy. They are measured in heat output or joules. 3500 calories if not burned off equal 1 pound of weight.

2. This answer will depend on what you eat in a day and how much exercise you do. But we will say 2000 calories in and 1800 calories out (or burned in exercise)

3. Gain weight since you would have an extra 200 calories a day. It would take 3500 calories to equal a pound so 3500/200 = 17.50 it would take 18 days

4. 3500/300=11.67 so 12 days

5. 3500/200=17.5 so 18 days

Answer 2

Calories give energy to your body, so for example if you eat a 2,000 calories meal you may gain weight but you will have more energy stored. I don’t keep track of the calories that go in and out. You will gain weight if you gain too much. It would take at least a month or two. It would take 7 days to gain one pound. Hope this helped
