251. Intra-Workout Carbohydrates: What Elite Athletes Know That Influencers Are Getting Wrong

Caffeine is so normal in training culture that nobody questions it anymore. But the shock is this: the same stimulant you're using to "perform" can be cutting blood flow, drying you out, wrecking sleep quality, and pushing cortisol up while you chase a better physique. If you're living on pre-workout and energy drinks, you might not be training with energy at all. You're training with stimulation, and the bill shows up later in recovery, muscle fullness, insulin sensitivity, and long-term performance. In this episode of the Kris Gethin Podcast, I dismantled the science behind why caffeine is working against every goal you are training for and what the most disciplined athletes are actually doing instead.   What's Discussed: (00:01) Why I recorded this at the Arnold Classic and what I noticed about energy drink culture (01:08) Why caffeine is normalized and why most lifters think they "need it" (02:00) Adenosine explained, and how caffeine can reduce vasodilation and the pump (04:24) The diuretic effect and why dehydration changes performance inside the muscle cell (06:26) Sleep architecture, recovery, and why slow metabolizers get hit hardest (08:05) Cortisol, chronic stress load, and the muscle loss risk nobody talks about (09:55) Insulin sensitivity, nutrient partitioning, and why this matters for body comp (11:05) The stimulant dependency trap and how tolerance quietly escalates doses (13:00) Paraxanthine explained, and why I use it instead of caffeine (14:22) The real takeaway for performance, physique, and longevity If you train hard and care about muscle, recovery, and longevity, but have never once questioned what your daily caffeine habit is actually doing to your body, this episode is required listening.

Most people training for performance, muscle, or body composition have been told that carbohydrates during training are unnecessary, counterproductive for fat loss, or only relevant for endurance athletes. But walk into the hotel rooms of the professional bodybuilders, UFC fighters, and motocross racers at the Arnold Classic and every single one of them is consuming carbohydrates mid-session, because when you understand how glycogen actually fuels high intensity output, the debate stops being a debate. In this episode of the Kris Gethin Podcast, I break down the exact physiology behind why skipping intra-workout carbohydrates is quietly costing you performance, muscle, and recovery, and the specific formula I have been using and refining for 21 years to fix it. What's Discussed: (00:01) Why this debate keeps confusing people, and what I saw at Arnold Classic (02:21) Glycogen, glycolysis, and why high-intensity training runs on carbs (04:45) Why intra-workout carbs can delay fatigue and help you finish as strong as you started (07:08) The 4 things an intra-workout protocol should cover (09:28) Key ingredients I use and what each one is doing physiologically (11:47) Real-world examples across bodybuilding, UFC-style training, and high-output sports (14:13) The practical takeaway, and what I am running next with my at-home trainer   Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred    Resources Referenced in This Episode: Red Light Therapy Brand: Red Light Rising Link: https://redlightrising.co.uk/Code: GETHIN5 Lumaflex, click here and use Code: KRISGETHIN (10% off) • Collagen BPC-157 TB-500 GHK-Cu KPV Cartilax Sigma / Bio Cartilage / Nova Cartilage Vesugen   Thank you to our sponsors: Biostack: NAD + Cell Shield from Biostack Labs https://biostacklabs.com/kris Unmatched Supps: Natural pre workout, recovery, and hydration support (KGC10 for 10% off)  

How many times have you told yourself, "This week I'm going to be consistent," then two weeks later you're back at day one, annoyed at yourself like you are the problem? The truth is, most people do not fail because they lack discipline. They fail because the system they are using is working against them. The commute, the crowds, the gym hours, the intimidation, the waiting for equipment. Every one of those is a compounding friction point that quietly drains your compliance until skipping becomes easier than showing up. In this episode of the Kris Gethin Podcast, I lay out the exact framework I am using to rebuild my physique from scratch, after months off training and stem cell treatment, entirely from home. No commercial gym. No excuses. Only a system that removes every reason you have ever used to skip a session, backed by the same behavioral science that explains why most training programs fail before week three.  What's Discussed: (00:00) Why this 12-week at-home trainer is happening (and what people voted for) (02:21) The real problem: friction disguised as "lack of discipline" (03:10) Why lowering activation energy increases compliance (03:55) Commute time and gym logistics as consistency killers (04:10) Overstimulation, stress, and why home training can improve execution (05:10) What this video trainer includes daily: training, cardio, meals, biohacks, travel disruptions (05:55) Peptides and why I can go deeper inside my community (08:00) Equipment, limitations, and how I'll show alternatives (including training around issues) (09:16) Why people quit at home: distractions and blurred boundaries (and how to fix it) (12:05) Nutrition, supplements, and the sustainability approach (13:00) Recovery and biohacks: red light, cold exposure, vagal nerve tools, sleep optimization (13:40) Travel reality: hotels, airports, and keeping the plan intact (14:02) Expected outcomes: lean muscle, conditioning, resilience, metabolic flexibility (16:15) How to access the 12-week video trainer   Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred    Resources Referenced in This Episode: Red Light Therapy Brand: Red Light Rising Link: https://redlightrising.co.uk/Code: GETHIN5 Lumaflex, click here and use Code: KRISGETHIN (10% off) • Collagen BPC-157 TB-500 GHK-Cu KPV Cartilax Sigma / Bio Cartilage / Nova Cartilage Vesugen   Thank you to our sponsors: Biostack: NAD + Cell Shield from Biostack Labs https://biostacklabs.com/kris Unmatched Supps: Natural pre workout, recovery, and hydration support (KGC10 for 10% off)  

Fat loss does not fail because of weak discipline. It fails because the body does not feel safe enough to release stored energy. Long before macros, cardio, or meal timing matter, the nervous system decides whether energy will be mobilized or defended.  When sympathetic tone dominates through late nights, artificial light exposure, chronic stress, stimulant reliance, and inflammatory inputs, the body shifts into conservation mode. Cortisol rhythm flattens, insulin sensitivity declines, thyroid conversion slows, leptin signaling weakens, and fat storage becomes protective rather than optional. In this episode, I break down why fat loss is governed by circadian alignment, mitochondrial efficiency, food quality, and autonomic balance. I explain how artificial sweeteners create metabolic prediction errors, how caffeine entrenches sympathetic dominance, why eating in a stressed state alters nutrient partitioning, and how sunlight, grounding, and predictable routines restore metabolic confidence.  I also explore inflammation, omega-3 to omega-6 balance, mitochondrial signaling, and the identity shift required to stop fighting biology and start working with it. What's Discussed: (00:00) Fat loss is a nervous system decision, not a calorie equation (03:05) Sympathetic dominance, cortisol rhythm, and why the body defends fat (07:58) Eating under stress, digestion breakdown, and hidden inflammation (15:30) Artificial sweeteners, insulin prediction errors, and dopamine disruption (19:08) Caffeine, chronic cortisol elevation, and metabolic rigidity (20:55) Circadian rhythm, sunlight, and mitochondrial energy allocation (26:18) Inflammation, omega balance, and why food quality shifts outcomes (31:23) Identity alignment and creating an environment where fat loss is allowed.   Resources Referenced in This Episode: Unmatched Supps Code: KGC10 (10% off) Link: https://www.unmatchedsupps.com Ra Optics Blue Light Blocking Glasses Code: GETHIN (15% off) Link: http://raoptics.com/gethin Red Light Rising (red light therapy products) Code: GETHIN5 Link: https://redlightrising.co.uk/ Lumaflex (localized red light therapy) Code: KRISGETHIN (10% off) Link: https://www.lumaflex.com/KrisGethin?sca_ref=4602702.myGSQTPeAr Bahe Grounding Trainers Code: KRIS15 Link: https://bahe.co   Thank you to our sponsors:  Biostack: NAD + Cell Shield from Biostack Labs https://biostacklabs.com/kris Unmatched Supps: Natural pre workout, recovery, and hydration support (KGC10 for 10% off)   Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred   

Injuries rarely fail to heal because the body is incapable. They fail because the healing sequence is interrupted. I see this constantly. People rest, the pain reduces, they feel better, and they assume the tissue has repaired. Then they return to training and it flares again. Healing does not happen through the absence of stress. It happens through the correct sequencing of inflammation, energy production, vascular integrity, and mechanical load. In this episode, I break down the real biology of recovery. I explain why blood flow and mitochondrial output are foundational, how peptides like BPC-157, TB-500, GHK-Cu, and KPV act as precision signals rather than force, and why stacking without timing can create more chaos than progress. We also discuss bioregulators, red light, collagen synergy, and the final instruction that completes healing: intelligent load. What's Discussed: (00:00) The biggest lie about healing and why rest alone fails (07:15) The biology of recovery: inflammation, repair, and remodeling (16:34) Blood flow, movement, and why vascular integrity comes first (24:18) Peptide sequencing: BPC-157, TB-500, GHK-Cu, and KPV explained (35:10) Why stacking without timing creates fragile tissue (44:03) Bioregulators, cartilage, and restoring cellular identity (48:11) Mitochondria, red light, and the energy required for repair (57:18) Mechanical load as the final instruction for complete healing Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred    Resources Referenced in This Episode: Red Light Therapy Brand: Red Light Rising Link: https://redlightrising.co.uk/Code: GETHIN5 Lumaflex, click here and use Code: KRISGETHIN (10% off) • Collagen BPC-157 TB-500 GHK-Cu KPV Cartilax Sigma / Bio Cartilage / Nova Cartilage Vesugen   Thank you to our sponsors: Biostack: NAD + Cell Shield from Biostack Labs https://biostacklabs.com/kris Unmatched Supps: Natural pre workout, recovery, and hydration support (KGC10 for 10% off)  

Sleep is the most overlooked variable I see in people who train hard, eat well, and still feel stuck. Clients come to me wanting better programs, better supplements, better plans, but when sleep is short or broken, the body simply does not cooperate. It shifts into a defensive state, holds onto fat, and makes progress feel harder than it needs to be. In this episode, I explain why sleep is the strongest predictor of fat loss, muscle retention, and long-term health. I walk through how poor sleep disrupts cortisol rhythm, worsens insulin sensitivity, blunts growth hormone release, and quietly works against even the best training and nutrition strategies. We also talk about circadian rhythm, phone use, light exposure, caffeine, and why fixing sleep only at night rarely works. I share the same hierarchy I use with clients, starting with consistency and environment before touching supplements or advanced tools. If your results have stalled, this conversation will change how you think about recovery and progress. What's Discussed: (00:18) Why sleep is the first thing I fix with every client (05:05) How poor sleep shifts the body into fat storage and survival (10:02) Cortisol, insulin sensitivity, and why effort stops working (15:05) Circadian rhythm, light exposure, and modern sleep disruption (20:01) Why more cardio backfires when sleep is compromised (25:03) Caffeine, artificial sweeteners, and hidden metabolic stress (30:33) Creating a sleep environment that supports recovery and fat loss (35:23) Why supplements and peptides only work after sleep is fixed (44:56) The core takeaway: sleep decides whether the body lets fat go Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred  Thank you to our sponsors:  Biostack: NAD + Cell Shield from Biostack Labs https://biostacklabs.com/kris  Unmatched Supps: Natural pre workout, recovery, and hydration support (KGC10 for 10% off)   Resources Referenced in This Episode: Unmatched Supps Longevity Sleep, pre-workout with paraxanthine Code: KGC10 https://www.unmatchedsupps.com Biostack Labs LineAct Plus https://biostacklabs.comIndia: https://trimlifestore.com RA Optics (Blue light blocking glasses) Code: GETHIN http://raoptics.com/gethin Red Light Rising (Red light therapy) Code: GETHIN5 https://redlightrising.co.uk/ Bahe grounding shoes Code: KRIS15 https://bahe.co JASPR Air Purifier https://jaspr.co UBlockout blackout window shades Organic / non-toxic mattress (general reference) Weighted blanket Grounding sheets (general reference) EMF exposure reduction (general discussion, no specific product) Red light therapy device (general morning use, not brand-specific in episode)  

Stem cells and regenerative medicine get talked about like they're magic. Fix the joint, fix the injury, get back to training. That mindset is exactly why so many people walk away disappointed or saying the treatment didn't work. I wanted to have a real conversation about what actually determines results once the procedure is over. In this episode, I'm sitting down with Scotty Nelson at CPI in Tijuana to talk about what most people misunderstand about recovery and timing after stem cell treatments. We get into why doing more too soon can work against you, why some people feel changes quickly while others don't, and how rushing the process quietly sabotages long-term healing. We also talk about the difference between symptom relief and true tissue repair, why expectations matter more than people realize, and how mindset and environment influence outcomes just as much as the treatment itself. If you care about durability, performance, and staying active long term, this conversation will change how you think about recovery.   What's Discussed: (00:00) Why "doing more" after treatment often backfires (05:42) Inside CPI and how regenerative medicine has evolved (11:30) Who stem cells actually help and who they are not for (18:55) The biggest recovery mistake after stem cell therapy (26:10) Why symptom relief is not the same as tissue healing (33:40) Recovery timelines, inflammation, and why patience matters (41:18) Stem cell dosing, viability, and misleading marketing claims (49:30) Longevity beyond joints: lungs, heart, brain, and resilience (56:45) Environment, mindset, and why healing fails without both (1:04:10) Where regenerative medicine is heading next Find more from Kris: Website: https://www.krisgethin.com/   Instagram: https://www.instagram.com/krisgethin/  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred    Find more from Scotty Nelson:  https://www.instagram.com/scottyotm  https://cpistemcellpodcast.com/  https://cellularperformanceinstitute.com/    Resources Referenced in This Episode: Regenerative and medical treatments mentioned • Stem cell therapy (orthopedic and IV) • Hypoxic stem cells • Mesenchymal stem cells (MSCs) • Wharton's jelly • Cord blood–derived products • Stem cell lysate • Growth factors • Exosomes (discussed and intentionally not used in their protocol) • IV stem cells • Penile stem cell injections (P-shot, discussed cautiously) • Facial stem cell injections • Scalp stem cell injections (hair) Supportive and adjunct therapies mentioned • Hyperbaric oxygen therapy (HBO) • IV ozone therapy • Myers' cocktail IV • Physical therapy Aesthetic and skin treatments mentioned • Microdermabrasion • PRP facials • Morpheus8 (radiofrequency microneedling device) Diagnostics and testing mentioned • MRI imaging • Echocardiogram • Large blood panels • Genetic testing • Biological age testing • Methylation testing • Horvath clock • Levine (PhenoAge) clock Medications and medical references • Cortisol (as a drug reference) • Pain medications (general) • Asthma inhalers (Ventolin, Seretide, Beclomethasone mentioned historically)

After decades of training hard, competing, coaching, and living inside a high-intensity routine, you start to understand that discipline evolves. There comes a point where doing more is no longer the smartest decision, even when you are fully capable of it. In this episode, I explain why I am temporarily stepping away from resistance training as part of a structured stem cell recovery protocol, and why following that protocol matters more than ego, habit, or momentum. I talk about restraint as a form of discipline, how recovery phases challenge identity, and why so many driven people struggle when visible progress disappears. We unpack what happens when you negotiate recovery, why biology always wins, and how competing stressors slow healing and longevity. I also share how I am approaching movement, sleep, stress regulation, and recovery with intention during this phase. This conversation goes beyond bodybuilding. It applies to anyone learning when to slow down so they can keep going for decades. What's Discussed: (00:02) Why I'm temporarily stepping away from resistance training (01:11) How stem cell recovery protocols remove competing stressors (02:31) Discipline through restraint and long-term thinking (04:41) Why recovery phases challenge identity and confidence (06:21) Why negotiating recovery protocols undermines healing (08:10) How intentional movement supports recovery (10:27) Detaching self-worth from gym performance (16:23) Knowing when biology is asking for repair Thank you to our sponsors:  Unmatched Supps: Natural support for training performance, hydration, and recovery without stimulants or artificial load.

After years of bodybuilding, coaching, and pushing my body to extremes, you start to see patterns you can't unsee. People chase fat loss harder and harder, slash calories, live on stimulants, and follow rigid nutrition rules that promise control and discipline. It works for a while. Then energy drops. Recovery slows. Hormones take a hit. Inflammation creeps up. And the cycle starts all over again. In this episode, I break down eight nutrition mistakes I see repeatedly sabotaging health and long-term progress. We talk about extreme calorie deficits, processed protein overload, missing micronutrients, cutting fats, binge eating disguised as cheat days, bro science diets, stimulant dependence, and removing food groups without understanding individual biology. I explain how these habits impact thyroid function, hormones, gut health, brain chemistry, sleep, and biological aging. If your goal is strength, resilience, and a body that still performs decades from now, this episode will challenge how you think about nutrition, discipline, and sustainability. What's Discussed: (00:37) Why extreme calorie deficits damage metabolism and hormones (03:56) The binge-restrict cycle and why the body starts expecting it (07:13) How processed protein foods quietly drive inflammation (09:02) Why ignoring micronutrients undermines gut and recovery health (10:09) The risks of cutting entire food groups without understanding biology (12:07) What I learned after testing vegan, keto, and restrictive diets (15:28) Cheat days vs refeeds and how binge eating rewires the brain (21:09) How stimulant dependence disrupts sleep and accelerates aging Products Mentioned in This Episode: Unmatched Supplements Code: KGC10 for 10% off Link: https://www.unmatchedsupps.com Unmatched Outlier (pre-workout) Code: KGC10 for 10% off Link: https://www.unmatchedsupps.com BH2K (Be Harder 2 Kill) Code: KGC10 for 10% off Link: https://www.unmatchedsupps.com Biostack Labs Glucose Disposal Agent (GDA) Affiliate relationship mentioned Link: https://biostacklabs.com Carbon 60 Olive Oil (ESS60 / My Vital C) Code: GETHIN Link: https://www.myvitalc.com/gethin/ Paraxanthine Continuous Glucose Monitor Electrolyte Drink Ice Bath / Cold Exposure Grass-Fed Whey Isolate Protein Bars Processed Deli Meats and Sausages Virgin Olive Oil (general, high-quality source)   Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred 

After spending decades in bodybuilding, you start to notice patterns that are difficult to ignore. People who once looked indestructible begin to age faster than expected. Recovery slows. Energy drops. Joints ache. Hormones suffer. And yet the narrative persists that bodybuilding itself is the cause. From my experience, that conclusion misses the real issue. In this episode, I explain why muscle, intensity, and hard training are not the problem. The real driver of accelerated aging is chronic stress without sufficient recovery. We look at how excessive volume, persistent inflammation, constant insulin stimulation, poor sleep, digestive strain, and psychological pressure quietly compound over time. I break down how the same training stimulus can be adaptive or degenerative depending on how well it is recovered from and integrated into life. If you want strength, resilience, and longevity rather than short-term results, this episode will challenge how you think about effort, discipline, and recovery.  What's Discussed: (00:01) Why bodybuilding is often blamed for accelerated aging (01:45) What decades in the industry reveal about long-term outcomes (03:20) Why muscle and hard training are not the real problem (05:10) How chronic stress shifts the body from growth to survival (06:55) When inflammation stops being adaptive and starts aging you (08:40) Why training volume without recovery breaks hormonal health (10:25) How poor sleep and constant stimulation accelerate aging (14:05) Why aligning bodybuilding with biology protects muscle for life Find more from Kris: Website: https://www.krisgethin.com/   Instagram: @krisgethin  Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred    Products mentioned in this episode: Red Light Therapy Red Light Rising – https://redlightrising.co.uk/ – GETHIN5 Lumaflex (localized red light therapy) – https://www.lumaflex.com/KrisGethin?sca_ref=4602702.myGSQTPeAr – KRISGETHIN Molecular Hydrogen (Hydrogen Rich Water) Drink HRW – https://drinkhrw.com/pages/h2-in-sports – GETHIN Carbon ESS60 (Carbon 60) ESS60 My Vital C – https://www.myvitalc.com/gethin/ – GETHIN Grounding / Earthing Bahe Grounding Trainers – https://bahe.co – KRIS15 Glutathione EBO2 Therapy Stem Cell Therapy Peptides
