This article is a summary of the research study: Chrono-nutrition: a review of current evidence from observational studies on global trends in time-of-day of energy intake and its association with obesity
Our body’s internal clock, known as the circadian rhythm, plays an important role in regulating our eating habits and metabolism. However, we have limited knowledge about how people distribute their energy intake throughout the day and whether it is linked to obesity. This review examines global patterns of energy intake timing in the general population using data from surveys and long-term studies. It also summarizes the evidence regarding the association between energy intake timing and obesity.
Based on the identified studies, it was found that there is a wide variation in the timing of energy intake among different countries and regions. People’s eating patterns differ significantly, with some consuming more energy earlier in the day and others later in the evening. When it comes to obesity, the association with energy intake timing varies greatly. Some studies indicate a positive connection between consuming more energy in the evening and obesity.
In conclusion, this review highlights the global trends in energy intake timing and the variations observed across countries. These differences may have important implications for health, emphasizing the need to understand the social and environmental factors influencing eating patterns. Moreover, the evidence regarding the association between energy intake timing and obesity is inconsistent. Collaborative efforts involving multiple countries and regions are necessary to gather more data and enhance our understanding of the role of chrono-nutrition in promoting health.
