Eat *This* If You Consume Seed Oils, Best Way To Combine Strength & Cardio, Peptide "Stacking" Rules & More! Solosode #504

Full show notes: https://bengreenfieldlife.com/504 In this solosode, you'll get the latest research on three questions I keep getting asked. First, seed oils: a brand-new randomized controlled trial put 52 adults on either a low or a typical Western intake of linoleic acid for 12 weeks, and the results are important less for what they found than for what they didn't. You'll hear why arachidonic acid didn't move, why EPA dropped instead, what that does to your inflammatory balance, which seed oils I still think are worth avoiding, and the one dietary adjustment that matters most if seed oils are part of your diet. You'll also learn the surprisingly small amount of strength training that delivers the biggest longevity payoff, according to a 30-year study of more than 147,000 people, plus why pairing it with cardio is the single best exercise combination for blood pressure. I break down concurrent training, the interference effect between AMPK and mTOR, and when combining strength and cardio in one session helps you versus when it holds you back. Finally, I answer a listener question on peptides with six practical rules for stacking them safely, including which ones should never share a syringe, which ones cancel each other out at the receptor, and an honest look at how thin the human evidence really is behind the popular Wolverine stack.
