#370 - AMA #76: Peter evaluates longevity drugs, aspirin for CVD, and strategies to improve muscle mass — proven, promising, fuzzy, noise, or nonsense?

What It Covers

Peter Attia evaluates longevity interventions using a five-tier framework: proven, promising, fuzzy, noise, and nonsense, covering GLP-1 agonists, aspirin, and muscle-building strategies.

Key Questions Answered

• •Evidence Framework: The five-category system ranks interventions from proven (well-established with high-quality data) through promising, fuzzy, and noise, down to nonsense (data refutes claims), providing clear evaluation standards.
• •Scientific Flexibility: Strong convictions loosely held separates great scientists from good ones—willingness to change positions when new data emerges prevents clinging to disproven beliefs, similar to successful investors adjusting theses.
• •Geroprotective Evaluation: The episode examines whether metabolic drugs like GLP-1 agonists and SGLT-2 inhibitors have unique anti-aging effects beyond metabolic improvements, plus methylene blue, telomere supplements, and protein interventions.
