Summary

This study compares the effects of a ketogenic diet (high fat, very low carb) and a vegetarian diet (plant-based) against a standard mixed diet on gut bacteria, inflammation, and blood markers. Over 12 weeks, 200 adults aged 18-60 will provide stool and blood samples to track changes. The goal is to understand how different eating patterns influence gut health and metabolism.
