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 (BMI)

_ 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:

 

      Fat – 5 grams =  ________ calories

 

      Carbs -  _______ grams = 40 calories

 

      Protein – 20 grams = ________ calories

 

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

Food Grams Cal

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:

ANSWERS: 

              

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

 

·         Body Composition (lean mass vs. body-fat)

2.)   The word “calorie” relates to:

·         Combustion (to produce energy)

3.)         Make the following conversions:

Food	Grams	Calories
Fat	5	45
Carbohydrate	10	40
Protein	20	80

 

 

 

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

·         Minimum amount of calories required for vital bodily functions during a relaxed, reclined and waking state

 

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

·         Through a slight negative energy balance where the caloric expenditure slightly exceeds the caloric intake

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

·         Stored glycogen (produced from carbohydrates)

 

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

·         False

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

·         True

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 answers are correct!
