Summary

Ever wondered which diet actually works? Or if artificial sweeteners are as dangerous as the internet makes them sound? In this Fitness Friday episode, I sat down with nutrition expert Dr. Layne Norton to cut through the diet noise. We break down why personalization beats every trend, what the research really says about diet soda and sweeteners, and why the “best diet” looks different for every person. If you want straight answers, not fear-based headlines, this conversation will challenge a lot of what you think you know. Dr. Layne Norton is the founder of BioLayne, a company built on science-driven coaching and real-world experience. He has coached more than 70 athletes to pro status and helped thousands rethink nutrition with evidence instead of hype. Layne holds a BS in Biochemistry and a PhD in Nutritional Sciences, where he trained under one of the leading researchers in protein metabolism.
