The 5 Biggest Longevity Myths—and What to Do Instead

Longevity requires prioritizing foundational health habits over the latest biohacking trends. Obsessing over weight ignores the critical role of muscle mass, which is essential for mobility and metabolic function as one ages. Supplements should be treated as secondary to core pillars like nutrient-dense food, consistent sleep, and regular exercise. Biology functions through a cycle of repair and rebuilding; excessive fasting to induce autophagy can hinder muscle maintenance, which requires mTOR activation through protein intake and resistance training. Furthermore, alcohol consumption provides no health benefits and acts as a carcinogen, contradicting common longevity myths. Rather than relying on genetics or expensive interventions, focus on modifiable behaviors—such as strength training and metabolic health management—to improve gene expression and ensure a high healthspan, allowing for independence and vitality well into later decades.
