The conversation, filled with practical takeaways and humor, covered topics ranging from dietary choices to exercise routines, sleep hacks, and even the science behind supplements. In this blog post, we will explore the key insights shared during this informative discussion.
Dietary Choices and Nutritional Hacks
Ben shared his unique approach to nutrition, which includes a cyclic keto diet and strategic consumption of carbohydrates. He described how he manages his diet while traveling and the reasons behind his choices:
- Traveling with Oatmeal: Ben travels with oatmeal packets rich in protein, using them as a convenient breakfast option.
- Cyclic Keto Diet: He typically follows a low-carb diet throughout the day, allowing for carbohydrates in the evening to promote better sleep and energy levels for morning workouts.
- Benefits of Carbohydrates: Consuming carbs at night can help with serotonin production, which in turn aids melatonin production for better sleep quality.
The Science Behind Fasted Workouts
Ben emphasized the benefits of fasted morning workouts, explaining that:
- Fasted workouts may enhance focus and energy levels due to increased blood flow to the muscles and brain.
- The timing of meals around workouts is flexible as long as the total caloric intake remains consistent.
- Research does not support significant metabolic advantages to fasted workouts, but personal preference plays a crucial role.
Movement and Daily Activity
Ben is a strong advocate for incorporating movement into daily routines. He shared his methods for staying active:
- Using a treadmill workstation and incorporating kettlebells and pull-up bars around the home.
- Aiming for 18,000 to 20,000 steps a day, along with structured strength training and cardio sessions.
- Emphasizing the mental benefits of walking, including increased cognitive function and focus.
Cold Plunge Therapy and Hormetic Stressors
Ben discussed the benefits of cold plunges and their role in resilience and recovery:
- Cold exposure can enhance stress resilience, improve blood circulation, and aid recovery.
- While initial cortisol spikes may occur, continuous exposure can lead to improved responses.
- Few minutes of cold exposure post-workout can be beneficial without suppressing the body's natural inflammatory response.
Supplementation and Cognitive Support
Ben highlighted various supplements that he incorporates into his routine for cognitive enhancement and overall wellness:
- Nootropics: He mentioned several nootropic supplements, including Qualia Mind, Alpha Brain, and custom blends from Newtopia.
- Ketones: Drinkable ketones can provide energy and appetite control, particularly during travel or busy days.

Ben Greenfield's approach to health emphasizes vitality and functionality rather than merely extending lifespan. He encourages individuals to focus on being impactful and maintaining a healthy, active lifestyle. By incorporating movement, mindful nutrition, and strategic supplementation, one can enhance their quality of life as they age.
