    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. Next week: are GLP-1s cheating?

    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.  Hosted by Dr. Jordan Feigenbaum and Dr. Austin Baraki, co-founders of Barbell Medicine.

    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 fast The full two-hour episode and every back episode are on Barbell Medicine Plus, which can bundled with Premium. Resources and full references below.

    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?

  5. Jun 12

    Menopause Part 3: Body Composition, Bone, Brain, & the Fitness Changes (The Data vs the Influencers)

    Most women in 2026 are told menopause affects everything, the weight, the belly fat, the bones, the heart, the brain, and that the fix is hormones, supplements, and a proprietary protocol. The data tell a different story. Menopause does some of it, but not all of it. In this episode, Dr. Jordan Feigenbaum and Dr. Austin Baraki, with OB-GYN Dr. Loraine Baraki at the clinical handoffs, put real numbers on what menopause actually changes, e.g. body composition, the cardiometabolic shift around the final menstrual period, bone, cognition and sleep — and on the single biggest modifiable lever against what actually kills postmenopausal women.

    Menopause, Part 2: The 2,000-Year-Old Lie About Women and Exercise

    The story goes that hard exercise is risky for women, and that the idea is ancient. Both halves fall apart on contact. In this solo episode, Dr. Jordan Feigenbaum follows the claim that physical effort harms the female body across twenty centuries, and shows that almost every version of it arrived as a verdict first, with the science bolted on afterward. It runs from antiquity to the present: what Galen actually wrote, why Sparta trained its women on purpose, the Victorian “vital force” panic and Edward Clarke’s claim that studying would sterilize girls, the doctor who prescribed bed rest to women and the wilderness to men, and the 1928 Olympic 800m that was erased for 32 years over a collapse that never happened. Then the correction: the research that finally tested heavy training in older women and women with low bone mass, and what it found. The episode closes on 2026, where the guidelines say lift and the menopause market often says don’t. What we cover•    Why the “ancient Greeks” origin story for the no-hard-exercise rule doesn’t hold up. •    How a Victorian energy-budget idea became a medical case against women lifting and studying. •    The real story of the 1928 Olympic women’s 800m and the 32-year ban. •    The strong women who were relabeled as freaks or exceptions instead of counted. •    What Fiatarone’s nonagenarians and LIFTMOR actually showed about lifting heavy later in life. •    The cortisol panic, the fasting scare, and cycle syncing, examined against the data. •    Why the cautious messaging now comes from the market, not the medical guidelines.

    Menopause, Part 2: The 2,000-Year-Old Lie About Women and Exercise
  7. May 29

    Menopause, Part 1: What It Actually Is and the 24-Year WHI Correction

    In 1889 a French physiologist injected himself with guinea pig and dog testicle extract and published a claim of self-rejuvenation in The Lancet. That announcement kicked off a 200-year medicalization of menopause that ran through leeches and bromides, Premarin, the 2002 Women's Health Initiative, and the contemporary menopause-content space.  In Episode 1 of our three-part menopause series, Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through what menopause actually is at the hormonal level, which midlife symptoms are menopause-driven and which are not, the KNDy neuron mechanism behind hot flashes (and the new medication that blocks it), and the 24-year follow-up on the WHI that substantially revised the original conclusions. OB-GYN Dr. Loraine Baraki walks the clinical workup, the lab panel she actually orders, and how she handles patients arriving with DUTCH panels and compounded hormone protocols. If you have heard contradictory things about menopause hormone therapy from your primary care, your menopause coach, and your sister, that is not your fault. The evidence base has been revised in significant ways since the 2002 publication, and most patient-facing summaries are out of date.

    Is Creatine Causing Your Shin Pain? + Splitting Training, Endometriosis for Lifters | Direct Line · May 2026

    This is the free preview of the May 2026 Direct Line, our monthly AMA for Barbell Medicine Plus subscribers. Three reader questions answered in full. We open with a mid-30s woman with bilateral shin pain and exertional foot numbness who started creatine a month ago and is asking whether the supplement is the cause. We walk through the compartment syndrome literature, the 2025 case report being passed around online and misinterpreted, what creatine actually does to total body water (and what it doesn’t), the four compartment pressure studies that exist, the Waterman 2013 demographic data on who actually gets chronic exertional compartment syndrome, and the workup we would actually run if this person walked into clinic. Next, whether splitting your resistance training across the day affects strength and hypertrophy. We cover BBM’s general heuristic on frequency as a distribution tool for training load, the Schoenfeld meta-analyses on frequency (2016 and 2019), the wrinkle on cardiorespiratory fitness and exercise snacks, and where we go off the reservation compared to a strict evidence-based read. We close with endometriosis for the lifter, including the seven-year average diagnostic delay, the 2022 ESHRE guideline shift away from required laparoscopy, what the menstrual cycle and performance literature actually says (McNulty 2020), why the anti-inflammatory diet narrative is mostly noise, the iron and protein levers that matter, post-operative return-to-lifting timelines, the meet-timing question, and Austin’s clinical case walk on supplement stacks and GLP-1 anti-inflammatory effects. A dedicated full episode on endometriosis is coming this summer. The full unabridged Direct Line covers ten more questions, including where the GLP-1 strength trials actually are, why DEXA misleads on muscle mass loss, how we arrived at the Vital 5 weightings, the salt sermon for strongman, running shoes for casual runners, hernias and crunches in older lifters, the Bristol Stool Chart, Austin on coaching his residents, and a fresh reading list. Full episode on BBM Plus. Timestamps: Question 1 · Creatine and shin pain01:2713:21 Question 2 · Splitting your workout across the day13:2120:29 Question 3 · Endometriosis for the lifter20:29 What we cover: The clinical workup for chronic exertional compartment syndrome and why creatine is rarely the culprit. The Schoenfeld frequency literature and why training load matters more than the day it’s distributed across. Endometriosis basics including diagnostic delay, prevalence, and the 2022 ESHRE guideline change. Why most endometriosis “diets” don’t have evidence behind them, and which nutrition levers actually matter (iron, protein, energy availability).
