Marc Bates, a leading metabolic health coach, has announced the release of his latest YouTube video addressing critical misconceptions about protein intake, leucine thresholds, and their impact on muscle preservation and metabolic function.

The video emerged from Bates' observations of clients who struggled to build lean muscle despite consistent gym attendance and adequate food consumption. These clients, particularly those over 60, experienced frustrating plateaus in muscle development.

"When so many clients were still failing to make ground in building lean muscle, I realized there was a fundamental gap in understanding about protein requirements," Bates stated. "They would complain that they're going to the gym constantly, eating a good amount of food, but they could not gain any muscle mass, especially if they were over 60."

The video specifically addresses age-related changes in protein metabolism that many overlook. According to Bates, individuals 60 and older face unique challenges in protein utilization.

"People 60 and over, or maybe 65 and older, definitely need more high quality protein because it's harder for them to digest protein, they don't absorb quite as much as amino acids, and the mTOR signaling needs more leucine to activate," Bates explained.

The educational content focuses on the leucine threshold, a critical factor in muscle protein synthesis that becomes increasingly important with age. Bates emphasizes how understanding these mechanisms can prevent the "skinny fat" condition and support long-term metabolic health.

The video is now available on Bates' YouTube channel, where viewers can access evidence-based insights on optimizing their nutritional approach for muscle preservation and metabolic function.
