Carnivore Diet: High Performance Training and Building Muscle | Ep 12
This interview episode features Dr. Anthony Chaffee in conversation with host Simon Lewis, focused entirely on training performance, muscle building, and how diet timing affects athletic output. Drawing from his years as a professional rugby player, Dr. Anthony Chaffee shares how he accidentally discovered that fasted training produced dramatically better results than eating before competition. Listeners learn the biochemical reasoning behind this: consuming carbohydrates raises insulin, which locks down fat stores and limits the body to a finite glycogen supply, while a fasted state allows continuous fat mobilization for an effectively unlimited energy source.
The episode digs into the persistent myth that carbohydrate loading is necessary for muscle growth. Dr. Anthony Chaffee explains that carbohydrates cause muscles to swell with glycogen and water, and promote intramuscular fat deposition (similar to grain-fed marbling in cattle), which creates the illusion of size without functional strength. By contrast, carnivore eating produces only lean, efficient muscle gains. He also references classic bodybuilders like Serge Nubret, who ate six pounds of meat daily and maintained an elite physique into his late 60s, as evidence that the steak-based approach predates modern bulking protocols.
Practical details around meal timing and training frequency are also covered. Dr. Anthony Chaffee describes gaining 12 kilos of lean mass in five weeks after returning to consistent gym training while eating to satiety on a carnivore diet, and explains why eating close to bedtime on a carnivore diet does not disrupt growth hormone production the way late-night carbohydrate consumption does.
Key Takeaways
- Training in a fully fasted state allows the body to tap into fat stores as an unlimited energy source, because insulin levels are low enough to permit lipolysis, whereas eating carbohydrates before exercise raises insulin for roughly 24 hours and restricts you to finite glycogen reserves.
- Avoid eating on the day of competition or intense training: Dr. Anthony Chaffee found that even a single meal mid-tournament would noticeably reduce performance and energy levels, while complete fasting through all games produced consistently superior results.
- Carbohydrate-driven muscle bulk is largely illusory: glycogen and water retention plus intramuscular fat deposition make muscles appear larger during a bulking phase, but functional strength does not increase and the size disappears during cutting, making the bulking-cutting cycle counterproductive.
- Eating carnivore and training hard can produce rapid, confirmed lean mass gains: Dr. Anthony Chaffee went from 92-93 kg to 105 kg in five weeks after resuming consistent gym training, with no change in body fat percentage, indicating all added weight was muscle.
- Eating to satiety late at night on a carnivore diet does not suppress growth hormone, because only carbohydrate consumption raises insulin, which is the mechanism that interferes with the peak growth hormone release that occurs approximately two hours after falling asleep.
- Classic elite bodybuilders including Serge Nubret (who ate roughly six pounds of meat daily and competed into his late 60s) and early Arnold Schwarzenegger built their physiques on essentially carnivore diets, demonstrating that high-level muscle development does not require carbohydrates.
