Weight Control: Better to Eat a Big Breakfast than Big Dinner

The importance of the time of day and our internal clock for food intake and energy metabolism is a very exciting research field. Future studies should investigate why we spend so much more energy after breakfast than after dinner

WeightControl.com:  What is the background for this study?  What are the main findings?

Response: The background for this study is that there is still the misbelief that it does not matter when we eat and that the only thing that counts is the energy balance of the whole day. However, since our body has an internal clock and many processes in the body, for example glucose metabolism, are subject to diurnal variations, we investigated whether diet-induced thermogenesis also varies during the course of the day.

Diet-induced thermogenesis is the energy our body spends for the digestion, absorption and transport of nutrients. We found that diet-induced thermogenesis after breakfast is more than twice as high as after dinner. We also investigated whether this difference in time of day depends on the amount of calories consumed. In both cases, high- and low-calorie meals, the body spends more energy after breakfast than after dinner.
