Decoding the Sweet Stuff (opens the original)
Read excerpt
Ask 10 people about Diet Coke and you'll get 10 completely confident, completely different answers. And somehow... they might all be a little bit right. This week we're breaking down what "fake sugar" actually means — because sucralose and allulose are as different from each other as coffee and cough syrup, and treating them like one category is where most of the confusion starts. Inside this episode:🥤 The real "cast of characters" — caloric sugars, artificial sweeteners, sugar alcohols, and the
The Last 20 lbs (opens the original)
Read excerpt
🧪 New Episode: The Last Rep Rule Quick question: when lifting weights, which reps actually build muscle — the first few, or the last few? The answer might tell you exactly why the last 10-20 pounds of a weight loss journey feels so different from the first 100. Inside this episode:💪 The muscle-growth science behind why the hardest rep is the one that counts🧠 Hormesis and stress inoculation — the real science of why moderate struggle makes you stronger⚖️ The surprisingly real phenomenon of "fit-s
The Scale is Not the Score (opens the original)
Read excerpt
This episode opens with an unexpected MVP: a book called The Art of Winning Tennis, picked up purely for the "75 Intentional" reading challenge despite not knowing much about tennis. The premise that hooked us: a score alone doesn't tell you how the game actually went — a 3-7 set could mean a dozen different stories. That single idea gets fully transplanted onto weight loss: the scale is the score, but it's not the game tape. we launch into a genuinely compelling case for tracking everything exc
Popcorn and Butter (opens the original)
Read excerpt
This one's got two very different rounds stitched together. Round one is a full-blown "Fat Things We Did"— the dive in, with genuine reverence, a friend's engineering marvel of a two-straw popcorn-buttering hose system, the dad-and-soufflé-cup butter-drizzle method, and a home-butter-in-a-thermos heist gone slightly wrong at a 1940s theater. Round two takes a hard pivot into the neuroscience of urges — dopamine anticipation vs. dopamine payoff, the marshmallow study, why cravings peak-plateau-fa
Cognitive Reserve (opens the original)
Read excerpt
This one's a deep-dive triple threat: cognitive reserve, the Nun Study, and superagers — all stitched together into one big argument for why "just use willpower" was always going to fail you. We open with a road-map metaphor (a brain with one highway vs. a brain with side streets and alternate routes), detour into a wild study about nuns whose brains had Alzheimer's-level plaque damage but no symptoms whatsoever, swing through Huberman's "superager" research and the anterior mid-cingulate cortex
