Timing of Meals for Weight Loss
Completed · Not applicable
Conditions studied: Overweight, Obesity, Weight Loss
In brief
While eating the majority of energy earlier in the day appears to have a positive effect on weight and cardiometabolic outcomes, it is not clear how eating earlier in the day influences other behaviors that have a circadian rhythm (sleep), other energy balance behaviors important for weight loss (physical activity), and self-reported feelings of appetite control (hunger and fullness). Thus the purpose of this study is to examine the influence of timing of eating on sleep patterns, physical activity, and self-reported feelings of appetite control. It is hypothesized that those who eat the majority of their calories earlier in the day will have greater weight loss than those who eat the majority later in the day.
