I think many people make food choices based on popular health “fads” (ex: claims that a low carb/high protein diet leads to instant weight loss) without regarding the impact on their microbial communities. Health fads are often very damaging to microbial communities because they generally don’t promote eating a well-balanced, diverse group of foods. For instance, following a zero carb diet restricts an individual from eating healthy food groups such a fruits and vegetables. I would assume that diets such as these can have detrimental effects on the gut microflora which need diverse foods to thrive.
