Q

How do we determine an appropriate energy intake for weight loss in obese patients?

Q

500 kcal will lead to a 1 lb or 0.5 kg loss per week. Explain the principle behind this

A

One pound is equal to 454 g of adipose tissues, where 87% of adipose tissue is fat.
0.87 x 454 g = 395 g of fat
395 g x 9kcal/g = 3500 kcal
3500 kcal/7 days= 500 kcal/day to induce 1 lb weight loss in one week

Q

What is important to consider when adjusting for an energy deficit?

A

We want to induce an hypo-caloric diet that has a large enough energy deficit to induce weight loss without inducing the physiological adaptations to starvation (under hormonal/hedonic control)

Q

In the high-protein diet for weight-loss, there was less reduction if fat-free mass - what does this mean?

A

That the diet spared endogenous protein breakdown, meaning that the individual will not experience a decrease in REE which will facilitate weight-loss

35
Q

High protein and low glycemic diets also experienced what?

Q

Name some stats about PA

A
  • 50% Canadians inactive
  • More females than males inactive
  • PA decreases with age
50
Q

Active adults have ____ decreased risk of premature mortality

51
Q

What is encouraging about PA for sedentary individuals?

A

A modest increase in PA has been associated with LAGE improvements in health status, especially in risk of mortality (taper off as aerobic fitness increases - more significant in men)

52
Q

Which diseases drastically decrease in risk, then stabilize as PA increases (curvi-linear relationship?) CODS

A small increase in PA can have large health benefits in reducing risks of diseases (CODS) and weight gain

  • Environmental
74
Q

What are some behavioural aspects of RA?

76
Q

What are some environmental aspects of RA?

A
  • Social support

- Life circumstance

77
Q

Selection criteria for weight management program is based on what? CFN

  • Composition
  • Food plans
  • Nutrition counselling
78
Q

What is intricately related in management of obesity? How is it sustained?

A

Diet, physical activity and behavioural modifications

Sustained by maintenance.

79
Q

Overall, what are some key recommendations you would make to a person living with obesity?

A
  • Assess readiness to change, state-of-change model ..
  • Diet high in protein (25-30%), <30% fat, normal range of carbohydrates that are low GI
