Background/Aims: Childhood obesity is a growing concern in Australia. For prevention and treatment of obesity it is beneficial to provide nutritional advice promoting the consumption of foods with a high level of satiety ('fullness') and low in energy ('calories'). The macronutrients in food: carbohydrate, protein and fat influence the body's internal signals that control appetite. Methods: Seven obese and 12 healthy weight adolescents 12e19 years were randomised to complete two testing days

Self-reported hunger and fullness, and appetite hormones or energy expenditure were collected postprandially over four hours. This was followed by an ad libitum lunch and a 24 hour food recall. Differences between groups were assessed using independent samples t-test. Results: Preliminary results to date indicate differences in appetite between weight status groups. Following the high protein breakfast, the obese group were significantly less hungry (p ¼ 0.024) compared to the healthy weight group after four hours. Following the high carbohydrate breakfast, the obese group consumed significantly less at the buffet lunch per kg of body weight (p ¼ 0.034) compared to the healthy weight group. Conclusions: The associations seen thus far indicate a relationship between macronutrient intake, body weight and subjective appetite sensations. Further recruitment to achieve the desired subject numbers, and ultimate analysis of the full set of outcomes including appetite hormones and energy expenditure will generate quality evidence towards the understanding and development of dietary advice for children.
