I don&#x27;t even know where to begin with all the pseudo-science half truths and ignorance in this post.  For starters, basically all the blue zone diets are high carb with low to moderate fat, lots of vegetables and fairly limited animal products.  Elite athletes prefer high carb diets by an overwhelming majority.  Multiple studies have demonstrated the beneficial effects of carbohydrate intake on the gut microbiota.  Just about the only population where low carb, high fat makes sense is sedentary people who are morbidly obese and highly insulin resistant.<p>By the way, congrats on finding a lifestyle that works __for you__.  Don&#x27;t go around preaching like it&#x27;s the one true path.  Nobody likes a zealot.
