Chapter One-Basic Physiology

Question 1

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

1. Pounds on the scale
2. Body Mass Index
3. Body Composition – lean mass vs. body fat
4. Body Surface Measurement

Answer 1

Body Composition – lean mass vs. body fat

Question 2

The word “calorie” relates to:

Answer 2

Combustion (to produce energy)

Question 3

Which conversion is correct?

1 gm fat = 4 calories

1 gm fat = 9 calories

1 gm fat = 12 calories

Answer 3

1 gm fat = 9 calories

Question 4

What is Basal Metabolic Rate (BMR) ?

Answer 4

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

Question 5

The most healthy way to decrease body-fat is:

1. Through a slight negative energy balance where the caloric expenditure slightly exceeds the caloric intake.
2. Drop your caloric intake below 800 calories per day.
3. Liposuction
4. Exercise at least 6 hours per day
5. Drink only water

Answer 5

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

Question 6

The body’s first choice for fuel is:

1. Stored fat
2. Stored glycogen
3. Stored protein
4. Aminos

Answer 6

Stored glycogen

Question 7

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

1. True
2. False

Answer 7

False

Question 8

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

1. True
2. False

Answer 8

True

Question 9

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

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

Answer 9

All of the above

Question 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:

1. Zig-Zag Dieting
2. Yo-Yo Dieting
3. Start-Stop Dieting
4. Bounce Back Dieting

Answer 10

Yo-Yo Dieting
