Interaction of Sleep, Diurnal Eating Pattern, Gut Microbiota, and Obesity

The data are fragmented and studies are focusing on interactions of sleep and obesity, eating pattern and obesity, or gut microbiota and obesity, but not the cross-talk of all these factors in the same individual or population. Therefore, we need a multifactorial approach to get a more deep insight on the obesity and weight regulation. Further, novel cost-effective tools to advance lifestyle changes are needed. Emerging evidence suggests that novel countermeasures, such as modulation of the timing of food intake, may be effective strategies in weight control and prevention of obesity. The goals of the proposed study are 1) to provide scientific basis for the relationship between subjective sleep quality, diurnal eating pattern, gut microbiome, and obesity, 2) to develop and test a pragmatic, cost-effective new tool to advance lifestyle changes using E-health approach, and 3) to compare differences in subjective sleep quality, diurnal eating pattern and gut microbiome at baseline 4) to compare changes induced by the E-health intervention among the three study groups and participants with different work schedules.
