Module summary

The obesity epidemic is an international problem, affecting people of all ages. Obesity is the consequence of an imbalance in energy intake versus energy expenditure, resulting in fat storage. Obesity increases disease risk in relation to diabetes, hypertension and cardiovascular disease. This module will deal with how energy metabolism is regulated by the human body and will introduce the strategies that exist for sustainable weight change. The module with also discuss the effect of physical activity and exercise on energy metabolism, health and wellbeing.

Objectives

The module aims to:
1) develop students knowledge and understanding of the principles of energy metabolism and energy balance in relation to metabolic demand and physical activity
2) develop students ability to interpret data related to body composition, energy intake and expenditure
3) initiate students ability to plan a suitable nutritional intervention in the context of energy balance
4) raise awareness of the current issues surrounding the obesity epidemic in developed and developing countries, including causes and treatment of obesity.

Learning outcomes
Upon completion of the module, students should be able to:
1) explain the physiological mechanisms underlying energy demand, utilisation and storage
2) explain the role of physical activity and exercise on energy metabolism and demand for energy and nutrients
3) explain the effect of obesity on health parameters, including discussion of the metabolic syndrome
4) explain how energy intake is regulated including physiological and psychological aspects of appetite, satiety and satiation
5) interpret experimental data related to body composition, energy expenditure and energy balance
6) discuss the issues surrounding the obesity epidemic in developed and developing countries including strategies for prevention and treatment
7) plan an intervention to influence energy balance that takes into account individuals needs and preferences.

Skills outcomes
- Undertaking and interpretation of nutritional assessment information in relation to body composition and energy balance
- Planning of an intervention to influence energy balance


Syllabus

- Review of energy metabolism including cellular mechanisms of energy production (concepts introduced in first year). Physiological regulation of energy intake, utilisation and storage including hormonal control.
- Physiological and psychological aspects on appetite, satiety and satiation.
- Effect of physical activity and exercise on energy and nutrient demand.
- Causes and consequences of obesity, including the metabolic syndrome: diabetes, hypertension and cardiovascular disease.
- Treatment of obesity using lifestyle and clinical approaches, including discussion of costs to society and barriers to change.
- Methods for assessment of body composition including advanced anthropometry.

Opportunities for Formative Feedback

- Students will have opportunities to obtain formative feedback during the seminar sessions.
- Progress will be formally monitored through course-work assignment (summative assessment).
- General feedback on assignment performance will be posted on the VLE, while individual feedback will also be provided upon marking of the assignment. It is envisaged that feedback from the first assignment will help students prepare for the exam.
