Description of intervention(s) / exposure
Other interventions - Egg diet
Other interventions - Egg-free Diet
Other interventions - Control Diet

Experimental: Egg Diet - Egg diet, contains 2 eggs per day and limits saturated fat to 6% of energy intake. Cholesterol intake is 600mg/day. Protein and carbohydrate levels will be maintained at 20% and 40% of energy intake, respectively. This diet will be followed for 5 weeks.

Active comparator: Egg-free Diet - Egg-free diet, limits cholesterol to 300 mg/day (no eggs) with saturated fat intake at 12% of energy intake. Protein and carbohydrate levels will be maintained at 25% and 40% of energy intake, respectively. This diet will be followed for 5 weeks.

Active comparator: Control Diet - Comparator diet based on the average Australian diet, limited to 1 egg per week, with saturated fat intake at 12% of energy intake. Cholesterol intake is 600 mg/day. Protein and carbohydrate levels will be maintained at 25% and 40% of energy intake, respectively. This diet will be followed for 5 weeks.
