Who can benefit from using it?
What does it mean?
What do I do with my results?

2. Total Body Composition Analysis “See What You’re Made Of”
Who can benefit from using it?
Athletes
To guide and monitor fat loss and muscle gain
Overweight people
Lose fat and gain muscle
Estimate how many calories should be eaten per day to lose fat
How much additional exercise should be done to lose fat
People with declining physical function/muscle
Older people
People who have been ill
People who have taken steroids (prednisone)
Measures skeletal muscle
then can exercise to improve the result

3. Total Body Composition (Fat) Analysis
Most accurate clinical method to measure:
Total body fat
Total body lean body mass
Skeletal muscle
Resting metabolic rate

4. What do we use? Dual-Energy x-ray absorptiometry
DEXA for short
The same technology used
By the TV show “The Biggest Loser”

5. How is a DEXA done? Uses very low levels of radiation
Safe
Uses less radiation than flying round trip Washington DC to Los Angeles
Measures the density of body parts (such as fat and muscle)
Person lays on a padded bed on back under the scanner
Scanner takes a picture of the body
Scan is painless and fast

6. What will I learn from the test?
Lean Muscle Mass
Fat Amount
Android fat vs Gynoid fat
Android fat increases risk for heart attacks
Resting Metabolic Rate
Relative Skeletal Muscle Index
Amount of muscle that is on arms and legs

7. LEAN Lean mass includes non-fat body parts
organs, muscle, bones, fluids
Higher the “Tissue %Lean”, the more muscular the body
GOAL: Increase muscle mass with exercise program

8. FAT Shows your body fat % Compares to your age group and gender
Tells you if you are “normal”, “overweight”, or “obese”

9. Example of body fat % chart comparing the result to other people of the same gender and age
See next slide on how to interpret result

10. This 24 year woman’s fat % lies just below the dark middle line (the average)
This person would be considered “average” and has a good body fat percentage
However, an athlete may need to have a lower body fat % and can use this baseline to improve upon through diet and exercise
If a person’s result shows “overweight” or “obese”… GOAL = lose weight through diet/exercise

11. ANDROIDvs GYNOID fat
Android (waist) fat is often associated with Apple-shaped body types.
Predicts risk for heart attacks
GOAL: Decrease amount of android fat with diet/exercise to decrease risk of heart attacks

12. RESTING METABOLIC RATE
Resting energy expenditure
Basal metabolic rate
Estimates # of calories you burn if you do nothing but rest
Result = calories per day

13. RESTING METABOLIC RATE
Used to figure out:
How many calories a day to eat in diet +
How much calories should be burned a day through exercise to lose fat

14. RELATIVE SKELETAL MUSCLE INDEX
Relative amount of muscle in the arms and legs
GOAL FOR ATHLETES: Use exercise program to improve this value on subsequent results
Improves athletic performance

15. RELATIVE SKELETAL MUSCLE INDEX
Useful also for:
Older people who are losing muscle mass that causes falls and loss of physical function
People who have lost muscle mass due to steroids (prednisone)
People who have lost muscle due to illness
GOAL: Perform regular exercise to increase muscle mass. Can see this when test is repeated

16. Total Body Composition Analysis “See What You’re Made Of”
How to use the results:
- Obtain current values for fat, muscle, and calorie use
- Use this to design an exercise and diet regimen
- Repeat test at intervals to monitor your progress
