The gut microbiome & hormones

Your gut is home to trillions of tiny organisms (bacteria, fungi, and others) that help digest food, make vitamins and signaling chemicals, and talk to your brain through the "gut–brain axis." Together, they're called your gut microbiome.

When you switch to a ketogenic or very low-carb way of eating, you're not just changing what you eat — you're also changing what your gut microbes are "fed."
