Following a keto diet for two weeks may impact gut health, particularly for those prone to digestive issues. The diet’s low fiber intake and high-fat content can alter gut microbiota, potentially leading to small intestine bacterial overgrowth (SIBO) or infections. A sudden reduction in carbohydrates can disrupt digestion, causing bloating, constipation, or diarrhea. Additionally, a lack of prebiotic fibers may weaken gut immunity, making it easier for harmful bacteria to thrive. If symptoms like abdominal pain, nausea, or irregular bowel movements appear, it’s essential to adjust the diet, reintroduce fiber, and consult a doctor for proper evaluation.
