The article you are citing isn't explained, which makes your article somewhat of a let down. For example, it would be nice to know how many study participants and how they long they followed them. Was it an RCT? Just an outline would be helpful. I've had nothing but improved labs in all areas on the keto diet and reviewed several studies that compare low fat and low carb diets that show improvements in health, not problems--and that includes outcomes in obesity and type 2 diabetes. Second, PCRM and Frontiers in Nutrition are vegetarian-based nutrition outlets. They have a considerable bias toward a plant-based diet.
