Seminar 2.2

• Metabolic Motors

2
Do Now

• Answer the following questions in your notes
• How often do you feel hungry?
• a. every 30 minutes
• b. around every 2 hours or so
• c. usually around mealtimes
• d. maybe once a day
• 2. Do you know someone who can eat and eat and
  eat anything he/she wants and still be hungry?

3
Metabolism

• Just like cars need gas, we need food to fuel our
  bodies.
• What allows you to think, breath, digest. . . to
  live? Food!
• We are born with a specific metabolic rate. Its
  a lot like the fuel efficiency of a car. Some of
  us are Hummers, some of us are Smart Cars, and
  most of us are in between.
• It is important to understand how our bodies
  work, and how much fuel (how many calories) we
  need to maintain our vehicles.

4
Calories

• Living organisms need to take in enough food and
  water to meet their energy needs.
• The main unit for measuring energy is the
  calorie.
• There are 2 scientific uses for the word calorie.
  You should write these down in your notes.

5
Calories

• 1. A calorie (with a lower case c) is
• the amount of heat required to raise the
  temperature of one gram of water one degree
  Celsius.
• This is used by chemists and physicists.
• 2. A Calorie (capitalized) is
• a unit of untapped energy equal to the amount of
  heat that is contained in food and released upon
  oxidation by the body.
• This is used by nutritionists
• (and HealthCorps coordinators).

6
Metabolism

• The word metabolism comes from the Latin for
  change.
• The dictionary defines it as the biochemical
  process of combining fats, proteins and
  carbohydrates with oxygen to release the energy
  needed for daily function and activity. . .
  Yikes.
• In other words, its when oxygen combines with
  the food in your body to change it into energy.

7
Your Metabolic Rate

• The amount of energy your body burns per day
  (just by doing normal things) is your metabolic
  rate.
• In the past, doctors came up with a formula to
  calculate metabolic rates. It was based on
  height, weight, age and sex.

8
Your Metabolic Rate (Contd)

• In the 1980s, through collaboration with NASA,
  scientists invented a machine to accurately
  measure a persons RMR.
• They needed to know how much energy each
  astronaut burned in order to figure out how much
  oxygen would be needed for space shuttle trips.
• I have one of these machines in my office, and
  guess what. . .

9
. . .

• Were all going to find out our own Resting
  Metabolic Rates over the next few weeks!

10

• Seriously guys, I know its exciting, but you can
  all stop cheering and clapping now.

11
Menu Activity

• Since we just discussed how our bodies need fuel
  to keep them going, were going to do an
  activity.
• Youre going to look at the menu and order what
  you would usually eat in a day (sorry, no
  substitutions).
• Write the items down in your notes.

15
Activities Menu

• Now that youve ordered your usual foods from
  the food menu, youre going to order your usual
  activities.
• Youre going to look at the menu and order what
  you would usually do in a day (sorry, no
  substitutions).
• Write the items down in your notes.

17
After youve made your choices

• You will receive envelopes containing various
  amounts of fake money.
• These represent how many calories your body burns
  in a day (your RMR) without doing any activity.
• You will also receive a list of how much money
  you spend on each food item and how much you earn
  from each activity.
• The idea is that you need to break even.

18
Breaking Even

• Count your money
• Add up the prices of each food item you ordered.
• Calculate how much money you earned from each
  activity.
• Add your activity earnings to the number of fake
  dollars in the envelope.
• Subtract the cost of all your food from the total
  from step 4.

19
Breaking Even (contd)

• The goal is to break even or to end up with a
  total of zero dollars
• Nothing left to spend
• No debt

20
So what?

• The dollars in this activity (as you may have
  figured out) correspond to calories.
• If you spent more money than you earned or had in
  your envelope, that is like taking in more
  calories than your body burns.
• If you had leftover money, that means you are not
  taking in enough calories to support your body.

21
Why it all matters

• When you burn more calories than you eat, your
  body does not have enough energy to function
  properly. This is called a Caloric Deficiency.
• When you break even, your body will maintain a
  consistent weight and have the energy it needs to
  function.

22
Break Down

• Our body needs fuel to function. Some fuels are
  better than others. YOU make the choice about
  what your body runs on, how well it runs, and,
  ultimately, how long it runs. Metabolism is
  unique to us all and this activity is meant to
  illustrate how important it is to know your
  metabolism and to make sure your body is getting
  what it needs to function and feel good.

23
Ticket Out

• On your ticket out, write down at least one
  question you have about metabolism.
