1. CALORIES

2. What is a Calorie???
A calorie is a unit of measure that indicates the amount of energy we obtain from a particular food.
The scientific definition of a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius.

3. ALL CALORIES!!!

4. What is a Calorie??
A calorie is put into your body through three different types of building blocks
Carbohydrates
1 gram of Carbohydrates = 4 Calories
Proteins
1 gram of Protein = 4 Calories
Fats
1 gram of Fat = 9 Calories
Overall, 3500 calories = 1 pound of fat.

5. What do Calories do??
The number of calories in a food is a measure of how much potential energy that food has.
So if you know how many carbohydrates, proteins, and fats that are in any given food, you know how many calories, or how much energy, that food contains.

6. How many calories does our body need?
Everyone has heard of 2,000 calories per day
That is just a rough average.
It depends on height, weight, gender, age, and activity level

7. How many calories does our body need?
There are 3 main factors involved with calculating how many calories your body needs.
Basal Metabolic Rate
Physical Activity
Thermic Effect of Food

8. Basal Metabolic Rate Basal Metabolic Rate
The amount of energy our body needs to function at rest.

9. Physical Activity Physical Activity
The amount of energy the body needs to be active.

10. Thermic Effect of Food Thermic Effect of Food
the energy expended by our bodies in order to consume
Examples: Bite, chew and swallow
and process our food
Examples: digest, transport, metabolize and store food.

11. Is a Calorie just a Calorie?
A calorie is just a calorie when we are talking about weight.
A calorie of fat, protein, or carbohydrate is all the same in the aspect of strictly weight.
They are all units of energy.
If you burn more than you take in, you will lose weight.

12. Is a Calorie just a Calorie?
A calorie is not just a calorie when we are talking about nutrition.
It does matter where those calories originated from.
Carbohydrates and proteins are healthier sources of calories than fats
Our bodies do need a certain amount of fat to function properly, but an excess of fat can have serious health consequences.

13. Calories, Fat, and Exercise
An accumulation of 3,500 extra calories is stored by your body as 1 pound of fat
fat is the body's way of saving energy for a rainy day.
If you burn 3,500 more calories than you eat, whether by exercising more or eating less, your body converts 1 pound of its stored fat into energy to make up for the deficit.

14. Exercises that Burn Calories
Using the weight of 180lbs a person can burn calories by:
Competitive basketball game cal.
Hiking cal.
Biking (leisurely) cal.
Playing catch with ball cal.
Competitive Soccer Game cal.
Snow Shoveling cal.
There are many ways to burn calories!!!
