Summary

This weight loss study will investigate the impact of calorie distribution across a day (large breakfast meals and smaller evening meals versus small breakfast meals and large evening meals) on body weight, and physiological and behavioral mechanisms regulating energy balance.

Participants will undergo 2 x 4 week energy restriction protocols in a randomized cross over design; big breakfast (45% of calories in the morning meal, 20% at dinner) and big dinner (45% of calories in the evening meal, 20% at breakfast). We predict that timing of eating will influence energy balance, because morning energy expenditure is amplified in comparison to the evening. This study will allow us to assess whether the increased energy expenditure in the morning is linked to natural biological circadian rhythm or behavioral adaptions.

Conditions

Interventions

OTHER

Big Breakfast

Weight loss diet (Calories fed to measured RMR) with calories distributed predominantly at breakfast (percent daily calories split between breakfast, lunch and dinner as 45-35-20%). The diet will be high protein (30% protein, 35% fat and 35% CHO) with all meals provided.

OTHER

Big Dinner

Weight loss diet (Calories fed to measured RMR) with calories distributed predominantly at dinner (percent daily calories split between breakfast, lunch and dinner as 20-35-45%). The diet will be high protein (30% protein, 35% fat and 35% CHO) with all meals provided.
