MedicalResearch.com: What is the background for this study?
Response: Given the relevance of blood sugar and blood lipid levels, we wanted to be able to quantify how much meal content, time of day, sleep, gut microbiome, other individual characteristics contribute to glucose and to develop models to describe how the interactions between individual characteristics, meal composition, other sources of variation on postprandial glycemia.
We also wished to compare glucose data to other postrpandial metabolic responses, specifically c-peptide and triglyceride levels.
MedicalResearch.com: What are the main findings?
Response: We found that although postprandial triglyceride and glucose responses were highly variable between individuals, a person’s response to the same meals was often similar and therefore to a large extent predictable. Any given individual generally responds comparably to different meals of the same macronutrient profile. This suggests that once we understand an individual’s postprandial response to specific foods, their response to other foods can be predicted.

MedicalResearch.com: What should readers take away from your report?
Response: That there are strong differences in how people respond to the same meal, but it is not because of our DNA. It has to do with our gut microbes, where we are health-wise, how much we sleep, what time of the day we feed, and what other things we eat before. These are things that for the most part we can modify if we understand the relationship between these various factors and our metabolic responses to meals.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: We are currently carrying out in-depth analyses gut microbiome links to post-prandial responses and also exploring the relationship between postprandial glucose responses and appetite and postprandial energy intake. This will help us modulate a person’s diet if they want to reduce appetite for weight loss. Our future research focuses on more thorough investigations of triglyceride responses and crucial pathophysiological related to cardiovascular disease.
