I have seen peer-reviewed papers mentioning the daily changes in gut microbiota composition according to dietary changes. See for example this paper:
http://genomebiology.com/2014/15/7/R89
My question is related to this one:
Relationship between our microbiome and personalized nutrition
If, according to these recently published scientific results, it takes a day to change the gut microbiota to adjust to the dietary change, and the presence of certain microbes makes food assimilation more effective,
Does this mean that alternating a protein-rich meat and dairy diet with a carbs-rich diet every day would make our microbiota switch daily and not have time to increase calorie uptake?
