Sunday Morning Protocol 2049: A Halloween Story About Optimization

1.4K views · 1d ago · 54:28

A Halloween story about a man who does every wellness protocol, then an honest grading of each one. Dr. Jordan Feigenbaum tells the story of Dale Mercer, Unit 4471, who lives through a fully optimized Sunday in the year 2049: morning light panels, cold plunges, a 31-capsule supplement tray, grey-market peptides, methylene blue, an eccentric-only lifting machine, a protein IV timed to the anabolic window, sleep and readiness scores, a glucose sensor, mouth tape, Zone 2 with…

How Much Cardio Should You Do? How Much is Too Much?

4.6K views · 1w ago · 1:11:25

How much cardio should you do, and does more of it ever become harmful? Cardiorespiratory fitness keeps improving with training load and nobody has found a ceiling. Getting fitter keeps lowering mortality risk as far out as anyone has measured. The one dose dependent harm that survives scrutiny is atrial fibrillation, and it shows up around six to seven hours a week of hard endurance training sustained for years.

How Much Lifting is Enough? How Much is Too Much?

6.4K views · 3w ago · 1:11:22

How much resistance training do you actually need, and is there a point where more stops helping? We trace the "lift weights twice a week" recommendation back to the 1989 study it came from, which found that three days beat two, and to the citation loop that turned it into a guideline anyway.

Where did the advice to not lift heavy weights come from?

8.1K views · 4w ago · 1:01:22

Nearly every warning you've heard about lifting weights was written down before anybody checked it. We trace where those warnings came from, starting with a Harvard student in 1854 and ending with a curve on a graph that's being used today to argue you can lift too much.

Is It Safe to Train When the Air Is Full of Wildfire Smoke?

2.4K views · 1mo ago · 44:05

Parts of the country now get a few weeks of wildfire smoke every year, and the obvious question is whether there is a point where the air is bad enough that the workout costs you more than it gives you. We went and looked. There is a real number, it comes from about 1.5 million people, and it is not the number that gets quoted.

Do You Need a Calorie Surplus to Build Muscle? | Dr. Eric Helms

13K views · 1mo ago · 2:06:14

Guest: Dr. Eric Helms

Most lifters have been told they need to eat in a Calorie surplus to build muscle. That rule has always come with a list of exceptions: unless you're new, unless you're carrying extra body fat, unless you're coming back from time off. Dr. Eric Helms joins Dr. Jordan Feigenbaum to work out what the rule is actually tracking, starting from a question with a real number attached: what does a pound of muscle cost to build? And then, do you need to be in a surplus to build muscle?

Is Obesity A Muscle Problem?

5.8K views · 1mo ago · 1:23:23

Muscle is where most of the glucose goes, and muscle insulin resistance is the first thing that breaks on the road to type 2 diabetes. Both of those are true, and neither one means that building more muscle is the treatment for obesity. This episode works through what actually decides whether a tissue handles fuel well: not how much of it you have, but how fast it's moving fuel through.

Who Needs Testosterone, and Who's Not Getting It I Signal Episode 4

4K views · 2mo ago · 1:31:22

Most men who start testosterone never needed it, and some who genuinely do never get treated. In the final episode of the Signal series, Dr. Jordan Feigenbaum and Dr. Austin Baraki work through who actually needs testosterone replacement, who got sold it, and what the evidence says about the risks that scared the field for a decade.

My Body My Choice? The Problem With Buying Unproven Peptides

2.9K views · 2mo ago · 6:51

“My body, my choice” is the argument for buying these peptides, and this segment takes it seriously before showing where it breaks. It covers what informed consent actually requires, what the courts have said, and then the part most people came for: what actually works for a stubborn tendon, and what would change my mind on BPC-157.

Topics: Both sides of the scale are blank · "My body, my choice" and informed consent · Abigail Alliance and United States v. Rutherford · What Right to Try actually covers · Oral capsules and WADA status · What actually works for a tendon

Your Fat Has a Storage Limit

2.4K views · 2mo ago · 49:37

In 2004 a surgeon removed about ten kilograms of fat from fifteen women and measured everything that mattered. Nothing improved. Four years later, it still hadn't. That result should have ended an argument about body fat. Instead the argument got more specific, and the version you've heard most recently is that visceral fat, the fat around your organs, is the dangerous kind. I've said a version of that myself on this show, and in this episode I expand upon it.

Is There a 30-Gram Protein Limit? Bones, the Cap, and What Protein Really Does

1.2K views · 2mo ago · 10:35

Three questions in one. Does protein leach calcium and weaken your bones? Can your body really only use 20 to 30 grams at a meal? And what does protein actually do for you? Feigenbaum walks the acid-ash bone hypothesis, the feeding study that breaks the per-meal cap, and the one benefit that holds up, holding onto muscle while you lose fat, but only if you train. It closes on how much protein you actually need and the two questions that matter more than the number.

Topics: The acid-ash bone scare · What whole-body calcium balance shows · If protein dissolved bone, big eaters would have the worst · The 30-gram per-meal cap · Why the cap claim is wrong · The 100-gram meal test (Netherlands, 2023)

Fen-Phen, Vioxx, and What a Missing Drug Trial Actually Costs

443 views · 2mo ago · 9:31

Before you decide a missing trial does not matter, look at what happened the last three times. Fen-phen, Vioxx, and a compounding-pharmacy meningitis outbreak that killed 64 people all followed the same structure that is in front of the FDA now. This segment lays out each one and what it should teach you about approving drugs on thin evidence.

They Removed the Tumor and the Weight Got Worse: Acquired Hypothalamic Obesity

371 views · 2mo ago · 25:17

The surgery works, the tumor is gone, the hormones are replaced, and the patient gains weight faster than before. This segment explains why: the operation touched the circuit that sets body weight. We walk the POMC brake and the AgRP accelerator, and set the record straight on leptin.

Topics: The name: a tumor built from tooth tissue · Surgery, and what it costs · The new mystery: gaining weight faster than ever · The diagnosis: acquired hypothalamic obesity · How the brain sets weight: the brake and the accelerator · What about leptin?

The Only Human BPC-157 Trial, and What It Actually Showed

881 views · 2mo ago · 10:27

People keep saying there’s finally a randomized trial on BPC-157. There is, and it does not show what they think. This segment goes through the one human trial line by line, why an improvement in the treated group is not proof the drug works, and why “it’s natural” and “it’s just a peptide” do not hold up. By the end you will know why these compounds meet the legal definition of a drug.

Topics: The one randomized trial · Why the numbers cross zero · The endpoint nobody can look up · Why "the treated group got better" is not proof · Wrong condition, wrong route, wrong dose · The rest of the human record

Lifting and longevity: is 1 hour a week really the limit?

3.4K views · 2mo ago · 46:10

A popular paper claimed the longevity benefit of lifting disappears once you train more than an hour a week. It's a real paper, but the claim is a misread. This is the free cut of this month's Direct Line, where Drs. Feigenbaum and Baraki also take on whether GLP-1s affect your mood, the "same calories, more weight loss" protein argument, and what you can actually do in the gym when you have chronic fatigue syndrome.

Topics: The paper: does lifting stop helping after an hour? · The newer 147,000-person, 30-year study · GLP-1s, mood, and motivation · The FDA reverses the suicide warning · What happened when they gave people a GLP-1 in a bar · Is a calorie just a calorie?

The FDA Peptide Panel Had 7 Members Who Sell Peptides

1.1K views · 2mo ago · 8:57

An FDA advisory committee voted to open a legal supply line for peptides like BPC-157. This segment walks through how they got in front of the committee, why the panel that passed them looks nothing like the panels that rejected these compounds for years, and what the conflicts of interest actually were. If you want to know who made this call and what they stand to gain, start here.

Why (and What) Fat Is Actually Dangerous: The Flux

2.2K views · 2mo ago · 8:37

Why do we care about body fat at all? Not the amount, and not just where it sits. We debut the garage analogy: storage capacity set before birth, overflow into the liver, pancreas, and heart, and flux, the difference between fat that's moving and fat that's parked. The prelude to the next episode.
