Have you read "The Microbiome Diet" by Raphael Kellman? Check it out. I just started doing the reset myself a few days ago. Essentially the microbiome is bacteria that lives in our body that tells the hormones what to do. It controls many many many functions in our body! It turns the switch to diseases on or off. The reset starts off with starving the "bad bacteria" by removing all "trigger foods" (such as dairy, grains, legumes -except lentils and chickpeas, sugar, peanuts, gluten, soy, any artificial ingredients. This is to eliminate the "bad bacteria" while feeding the good bacteria what they need to be the dominant in the body to assist you in weight loss, dopamine, seratonin, rev up the metabolism, getting quality sleep, clarity of thought, etc. It is a fascinating book.
