## Resource

Can ketogenic therapy help atrial fibrillation? What should you make of the KETO-CTA study? And do higher ketones always mean better results? In this Metabolic Mailbag episode, Dr. Bret Scher answers audience questions about cardiovascular health, ketosis, ketone levels, and how to personalize a ketogenic approach based on your goals and metabolic health. From AFib concerns to cholesterol controversies and troubleshooting low ketone readings, this episode tackles some of the most common questions in the keto community. In this episode, we cover: Ketogenic therapy and atrial fibrillation (AFib) The latest update on the KETO-CTA study LDL cholesterol, plaque, and cardiovascular risk Why ketone levels don't tell the whole story Raising ketones without sacrificing energy or muscle Carbohydrate intake and metabolic flexibility Fasting, protein, and thyroid considerations MCT oil, exogenous ketones, and other strategies to increase ketosis One of the biggest takeaways: context matters. Whether you're evaluating cholesterol, ketone levels, or cardiovascular risk, there is rarely a one-size-fits-all answer. Understanding your goals, metabolic health, and individual response is often more important than chasing a specific number. 🔎 Have questions about how to apply metabolic therapies effectively?
