Episode notes
INSIGHT

Why Testosterone Decline Is Overstated

  • Most reported testosterone declines are explained by obesity, age, and measurement issues rather than sweeping environmental causes.
  • Today’s fitness knowledge and tools make getting in shape far easier than in the 1970s, but many people still don’t use them.
INSIGHT

EDCs May Matter, But Evidence Is Small

  • Endocrine disrupting chemicals might matter but currently explain only a small fraction of health changes, with uncertain evidence.
  • We need more replication and scope in studies before blaming EDCs for major population-level declines.
ADVICE

Don't Demonize Seed Oils

  • Don’t scapegoat seed oils; randomized trials show many seed oils are neutral or healthier than saturated fats.
  • Focus on reducing junk food and overeating rather than banning seed oils alone.
