1

What percentage of Men and Women are classified as obese in the UK

23% Men
23% Women

2

What percentage of men and women are classified as overweight in the UK

44% Men
34% Women

3

What classification BMI under weight, healthy, overweight and obese under

<18kg/m2 - underweight
18.5-24.9 kg/m2 - healthy
25-29.9kg/m2 --> Overweight
> 30kg/m2 --> Obese

4

Which category is showing the greatest increase

Obese

5

What is the most common long term reason for individuals putting on weight

energy in (food) vs Energy out (Exercise) imbalance

6

What is the highest lifetime food intake

Water

7

What are the components of daily energy expenditure, and what is the percentage for sedentary and PA

1) thermic effect of feeding (8% sedentary | 8% PA)
2) EE of PA (17% sedentary | 32% PA)
3) Resting EE (75% sedentary | 60% PA)

8

What is the relationship between BMI and CVD mortality

Those with a higher BMI are dying at an earlier age

9

What are the medical complications with obesity?

Pulmonary disease, non alcoholic fatty liver, gall bladder disease, gynecologic abnormalities, Osteroarthritis, Cancer (breast, uterus, colon, cervis, oesophagus, pancreas, kidney and prostate), coronary heart disease, diabetes, dyslipidemia, hypertension, stroke and idiopathic intracranial hypertension

10

Excess fat on the thorax causes problems how

difficult to breath, and reduces lung volume

11

What can the increase in body fat (BF) % cause

orthopaedic implications

12

for every 5kg increase in weight, how much knee arthritis % increases

35%

13

what is the relationship between obesity and orthopaedic problems the can occur in a sedentariness

atrophy of the muscles

14

What conditions can the impact of obesity have on health

gall stones, strokes, cancers (colon and breast), and reproductive problems

15

What mechanical consequences does obesity have on health

osteoarthritis, chronic low back pain, breathlessness. sleep problems.

16

What percentage of obese are classed as MHO

15-30%

17

If an obese individuals metabolic function and response is fine, what does this mean

Their risk is no higher than normal weighted adults

18

What are the main causes of obesity

Genetics, metabolic, over-eating and decreased PA

19

What occurs if an individual has a faulty Leptin production or resistance

Suppresses appetite, leading to a decrease in fat and therefore leptin production. Effecting energy in and out of the body

20

Where is leptin produced

adipose tissue

21

If both parents are obese, what is the percentage that the child will be too, and who is more critical mother or farther?

70-80% - mother

22

If neither of the parents are obese, what is the percentage of the child being obese?

7-14%

23

what is the relationship in obesity and metabolic factors; and what defects can it be caused by

hypothyroidism, cushion's syndrome

24

What is Cushing's syndrome

overproduction of cortisol

25

What occurs when metabolic control of appetite goes wrong?

1) controlled by orosensory, gastrointestinal, and neuroendocrine factors
2) defects in pathways lead to dysregulation of appetite

26

What are the individual differences in metabolic factors

- Diet induced thermogenesis
- Energy Storage (> efficient fat cells)
- settling point

27

What is the settling point theory

Body defends a certain weight likes thermostat regulates temperature

28

Minnesota experiment 1940's - what was found

25% of body weight lost, referring as adlib or on low fat diet, and both groups regained weight and body composition to original set point

29

What is Passive Over consumption

individuals allowed to eat ad-lib diets containing difference fat levels will consume more energy with high fat diet than on high CHO diet

30

what occurs when individuals consume the same weight/volume of food at each meal?

can't sub-consciously adapt to varying energy densities
