Most anything I've read most people's "stats" (cholesterol, blood pressure) improve once on a keto diet.
It's interesting to see the emotional attachment naysayers have to low carb diets. I can understand advocates having an emotional attachment due to how it has changed their lives in a positive way, often after years if not decades of failure, but the strong emotional response it invokes in people whose lives are literally not affected in any way but are for some reason strongly repulsed by the very idea, almost as if there is something within the human psyche. Very interesting.
