Module 6

Question 1

1 kcal =___KJ?

Answer 1

=4.18KJ

Question 2

Metabolism:

Answer 2

The rate at which our body uses kcal

Question 3

Energy Balance:

Answer 3

E in = E out

Question 4

Total Energy Requirements (TEE)

Answer 4

TEE= Basal Needs (60-70%) + Activity (10-30%) + Thermogenesis (5-10%

Question 5

Basal Energy Expenditure (BEE)

Answer 5

Amount of Kcal needed to sustain basic life processes

Question 6

Basal Metabolic Rate (BMR)

Answer 6

Measurement of o2 used at rest, measured prior to getting up

Question 7

Methods to measure BMR:

Answer 7

• Ventilated hood (O2 intake/CO2 release)

Question 8

rough estimate of BMR:

Answer 8

BMR = 1.0 kcal/kg/h (men)
= 0.9kcal/kg/h (women)

Question 9

Resting Metabolic Rate RMR (=REE)

Answer 9

Same as REE
if often measured in place of BMR, Using Formula (Harris Benedict Equations)
10-20% higher than BMR

Question 10

What is thermogenesis?

Answer 10

An increase in metabolic rate that occurs in response to a stimulus

Question 11

types of Thermogenesis

Answer 11

1. stress
2. drugs/meds
3. exposure to cold
4. dietary induced thermogenesis (DIT)

Question 12

BMI Equation

Answer 12

BMI= Weight (kg)/height^2 (m)

Question 13

Benefits of using BMI

Answer 13

• Reasonably accurate predictor of current health and future morbidity
• compares well with various measure of body fat

Question 14

Limitations of using BMI

Answer 14

1. Not intended for non- adults
2. never for pregnant women
3. BMI cannot distinguish fat from lean body mass
4. BMI does not address the issue of where excess adipose tissue is carried/located

Question 15

Health problems associated with overweight and obesity

Answer 15

1. cardiovascular health (Coronary heart disease-CHD and ischemic stroke)
2. insulin resistance (type 2 diabetes)
3. dyslipidemia
4. hypertension (CHD)
5. etc.

Question 16

weight cycling (yo-yo dieting)

Answer 16

repeated cycles of weight gain, dieting, weight loss, then weight gain again (over time, it is common for individuals to gain more

Question 17

Healthy weight loss and long-term management

Answer 17

1. follow a sensibly balanced diet (one you enjoy!)
2. eating less kcal overall
3. enjoy regular physical activity

Question 18

A successful diet…

Answer 18

1. must be lower kcal (lose 1-2lbs/week=-500kcal deficit/day
2. must be adequate in all other nutrients (vt/min/fibre)
3. should have high satiety value
4. adaptable to family meals
5. reasonable cost

Question 19

predictors of success in weight control:

Answer 19

1. high social class= higher education
2. no family history of obesity
3. social support
4. physical activity
5. self acceptance
6. coping abilities
