Quiz 1 / Answers

Basic Physiology

 

1.)  The most accurate form of measurement for long-term health and weight-management is (check one):

• Pounds on the scale
• Body Mass Index (BMR)
• Body Composition (lean mass vs. body-fat)

2.)  The word “calorie” relates to:

• Combustion (to produce energy)
• Fat on your body
• Carbohydrate

3.)  Make the following conversions:

 

 

 

4.)   Basal Metabolic Rate (BMR) is the:

• Minimum amount of calories required for vital bodily functions during a relaxed, reclined and waking state
• Amount of calories required to heat a one (1) cup of water one (1) degree Celsius in one (1) minute
• Amount of energy used during an intense workout

5.)   The most healthy way to decrease body-fat is:

• Drop your caloric intake below 800 calories per day
• Through a slight negative energy balance where the caloric expenditure slightly exceeds the caloric intake
• Liposuction

6.)   The body’s first choice for fuel is:

• Stored fat
• Stored glycogen
• Stored protein

7.)   The body can convert fat into glucose to feed its nervous system and metabolism:

• True
• False

8.)   The body can convert protein into glucose to feed its nervous system and metabolism:

• True
• False

9.)   When caloric intake goes below BMR, as in commercial weight-loss programs, the body will:

• Perceive starvation and create a “survival” metabolism
• Burn muscle to fuel its energy requirements
• Slow down metabolism to reduce energy requirements
• Store even more body-fat to fend off the perceived threat of starvation
• All of the above

10.) People who continue to go on and off “restricted calorie” diet programs typically rebound to a higher weight after each round of dieting.  This rebound effect is known as:____________

• YO-YO  Dieting
