In this episode of The 5 Minute Signal, Performance Research Expert Aris Sterling breaks down the hidden cost of the 2026 metabolic revolution. As generic GLP-1 agonists flood the market and accessibility reaches an all-time high, a silent biological crisis is emerging: the massive liquidation of lean muscle mass. Sterling explores the "Muscle Debt" phenomenon—where users trade short-term fat loss for long-term metabolic bankruptcy. With clinical data now showing that up to 40% of weight lost through these modulators is lean tissue, the risk of "sarcopenic obesity" is no longer a theoretical concern; it is a clinical reality. This episode provides a reality-driven maintenance manual for those using metabolic modulators, focusing on the three tactical pivots required to protect your biological engine. Learn why the scale is a lying metric and how to engineer a "muscle-first" weight loss strategy that prevents the 43% weight-regain rebound seen in recent longitudinal studies.
