The Protein Scaries: What the Research Says About Your Kidneys, Cancer, Bones, and Body Fat
Every couple of years a new headline warns that the protein you eat is quietly hurting you. This year the target is your kidneys. Before that it was cancer, then your bones, then the claim that your body can only use twenty or thirty grams of protein at a meal. In this episode, Dr. Jordan Feigenbaum goes through the actual studies behind each scare: the kidney trials, the 2014 IGF-1 and cancer paper that started the panic, the acid-ash bone hypothesis, and the per-meal "cap." Each fear starts from a real mechanism, and each one was run straight to a frightening conclusion the clinical outcomes never supported.The take home is simple. For a healthy adult, protein is not the lever people think it is, and where a real signal exists (processed and red meat, or a kidney that is already diseased) it tracks the whole dietary pattern more than the protein number. The two things that actually decide your health here are whether you eat mostly real food and whether you train.Timestamps00:00 The protein scare cycle 01:23 The four fears 01:59 Kidneys: healthy kidneys under higher protein 06:22 Kidney disease: does cutting protein help? 09:38 Red meat and the dietary pattern, not protein 12:00 Muscle, aging, and lifting on a restricted diet 13:54 Cancer: IGF-1 and the 2014 study everyone cites 16:22 The age reversal, and what travels with protein 18:48 Bigger data, processed meat, and the IGF-1 tell 22:15 Bones and the acid-ash myth 25:13 The 30-gram cap 27:17 What protein actually does, and how much you need 32:20 The two questions that matterResources:Barbell Medicine coaching and templates: https://www.barbellmedicine.comPlus podcast subscription: https://www.barbellmedicine.com/shop/subscriptions/plus-podcast-subscription/Barbell Medicine Premium: https://www.barbellmedicine.com/shop/subscriptions/barbell-medicine-premium/Signal (book pre-order): https://www.barbellmedicine.com/shop/learning/signal/Our Protein Content:https://www.barbellmedicine.com/blog/protein-and-weight-loss/https://www.barbellmedicine.com/blog/protein-on-ozempic/https://www.barbellmedicine.com/blog/barbell-medicine-protein-recommendations/StudiesLevine et al.

Is It Really Just Calories In, Calories Out? Metabolism, Insulin, Hormones and Why Counting Fails
Is weight loss really just Calories in, Calories out? The equation is true, but "just count your Calories" is bad advice for most people, and almost every objection to it is pointing at something real. In part two of our energy balance series, Jordan Feigenbaum takes the biggest "it's not Calories, it's ___" claims (metabolism, thyroid, cortisol, PCOS, insulin, the type of food) and tests each against the best evidence. The verdict: none of them breaks the equation. Every one is a hand on a lever that moves Calories in or Calories out, not a hole in the math.In this episode: why your metabolism does not crash at 40, how small real metabolic adaptation actually is after weight loss, why hypothyroid weight is mostly water, what the cortisol and PCOS (now PMOS) data show, how absorption and cooking move Calories only at the edges, why even dietitians miscount their own intake, and why the carbohydrate-insulin model fails three tests, including the GLP-1 drugs that raise insulin and still produce the biggest weight loss we have ever approved.Part two of three: willpower, Calories in Calories out, then GLP-1 drugs.

Is Obesity a Willpower Problem? The Biology of Weight, Diets, and GLP-1s
Obesity roughly tripled in about 60 years, and the genes didn't change in that time. So if body weight isn't a willpower problem, what is it? Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through what actually sets your weight: the adoption and twin studies behind the genetics, the "defended range" your biology fights to hold, the food environment that does most of the eating for you, and where GLP-1 medications actually work. Along the way — why diets regain after you white-knuckle them, what The Biggest Loser six-year data show about resting metabolism, and four willpower myths worth retiring.

Direct Line (Free): GLP-1 Muscle Loss and Creatine, Bulking vs Cutting, One-Hour Training, & Detraining
Once a month we answer Barbell Medicine Plus subscribers’ questions on the Direct Line. This is a free look at June’s episode. We start with GLP-1 drugs and muscle: why DEXA overstates the loss, what resistance training actually does, and whether creatine is worth taking. Then whether bulking and cutting does anything the scale can’t already tell you, how to get real benefit from one training hour a week, and what happens to your muscle, strength, tendons, and bone when you take time off, including why muscle memory brings it back faster than you built it.What we cover:• GLP-1s and muscle: the DEXA problem, resistance training, and creatine• Bulking vs cutting vs just maintaining, and a health-first way to choose• Training on one hour a week: the least that still moves the needle• How fast you lose muscle when you stop, and why it comes back fastThe full two-hour episode and every back episode are on Barbell Medicine Plus, which can bundled with Premium.

Menopause Part 4: Training, Protein, Cortisol, Hormone Therapy, & Bone Density
Is there really a “menopause-specific” way to train, eat, and supplement — or is most of it marketing? In the finale of our 4-part menopause series, Drs. Jordan Feigenbaum and Austin Baraki go straight to the evidence on building muscle and bone before, during, and after the transition.We cover whether menopause blunts your response to lifting (the Isenmann 2023 head-to-head trial and the 2026 meta-analysis of ~4,000 women say it doesn’t), the one-index-card prescription that actually works. Then we work through the loudest claims in the space — cortisol “wrecking” your fat loss, anabolic resistance, the protein and creatine hype, hormone therapy as a cure-all, and “you need a different paradigm” — steelmanning each before we push back. We close with the strongest case in the whole space: heavy lifting for bone density (the LIFTMOR trial), the pelvic-floor evidence, your three biggest fears answered, and how to tell a good coach or clinician from a bad one.Claims discussed are associated with Stacey Sims, Mary Claire Haver, Mindy Pelz, and the broader functional-medicine space. We push back on the claims, not the people.Timestamps:0:00 The 90-year-olds who tripled their strength 1:10 Why this matters: heart disease and falls, not vanity 2:28 Can women still build muscle after menopause?
