CHAPTER 9 – WEIGHT MANAGEMENT
Review questions: 1,2,4,5,7
1. Describe how body fat develops and suggest some reasons why it is difficult for an obese person to
maintain weight loss. (pp. 292–295)
Can be referred to as an epidemic due to rapid rise
Excess energy stored in fat cells of adipose tissue
Amount of fat = number & size of fat cells
oWhen enlarged stimulate cell proliferation
oObesity = person’s fat cells increase in number and/or size
When energy out > energy in, size of fat decreases but not their number
Hence, weight lost can be regained rapidly as there are many fat cells readily fill
2. What factors contribute to obesity? (pp. 295–302)
Activity of LPL
omakes fat storage especially efficient
Gender
orelease of lower-body fat is less active in women
oRate of fat breakdown = lower in women
Genetics
oDetermines a person’s susceptibility to obesity
Environment – our daily circumstances
oExposed to abundance of high-kilojoule, high-fat foods = overeating
oAtmosphere: visual cues that stimulate additional eating
oAccessibility: the ease & convenience of obtaining food
oSocialising: eat during social interaction
oDistractions: i.e. keeps eating until finish a TV show
oIf offered a variety, tends to eat more
oServing containers – how big/small the plate is
oSocial inequalities: energy dense foods (high in fat/sugar) = cheapest way
to provide daily energy requirements
oPhysical inactivity
3. List several aggressive ways to treat obesity and explain why such methods are not recommended for
every overweight person. (pp. 307–309)
4. Discuss reasonable dietary strategies for achieving and maintaining a healthy body weight. (pp. 309–
314)
