Question: does low carb high fat diet cause diarrhea?
Answer: On a high-fat diet like keto, you're all of a sudden eating lots more avocado, nuts, seeds, meat, olive oil, and other fats than normal—which can disrupt digestion. “When you switch to this high fat of a diet, it can cause diarrhea,” says Hultin. Artificial sweeteners and sugar alcohols can be rough on the stomach.
