Do This to Lose Fat & Build Muscle at the Same Time | Dr. David Sinclair

For decades, we've been told that losing fat and building muscle at the same time is impossible, especially as we age. But the latest research reveals a different story: body recomposition isn't just possible for seniors over 65, it's one of the most powerful strategies for staying biologically young, mobile, and independent. In this video, we break down the complete science-based system for transforming your body composition, focusing on the fundamentals that actually work: optimal protein intake, strategic resistance training, daily movement through walking, quality sleep, and targeted supplementation including creatine, omega-3s, vitamin D, and urolithin A for mitochondrial health. This isn't about extreme dieting or spending hours in the gym. It's about understanding how your body adapts and giving it the precise inputs it needs to build muscle, burn fat, and regenerate at the cellular level.

Whether you're just starting your fitness journey or looking to optimize your current routine, this comprehensive guide offers practical, evidence-based strategies you can implement immediately. We explore why traditional weight loss often leads to muscle loss, how sleep deprivation can suppress muscle protein synthesis by up to 18 percent, why walking is one of the most underrated longevity exercises, and how proper glucose management directly impacts your ability to lose fat. If you're ready to stop chasing numbers on a scale and start rebuilding your body from the inside out, this video will show you exactly how. Share your thoughts in the comments, let us know which strategy you'll implement first, and don't forget to subscribe for more evidence-based content on aging powerfully and living longer with vitality.
