- Exercise immediately after landing
- Getting sunlight for circadian rhythm adjustment
- Learning what works through trial and error
22:37 – Restriction vs. Freedom Philosophy
Ben explains his approach to nutrition:
- No foods should be off-limits
- All diets create some form of restriction (keto=carbs, carnivore=everything but meat, etc.)
- Humans psychologically resist restriction

28:36 – Exercise as Medicine
Dr. Barrett compares exercise to medication requiring proper dosing:
- Most powerful medication available
- Need to dose properly for maximum efficacy
- Trap of constantly increasing intensity/volume
- Importance of rest days
- Exercise not ideal for weight loss due to metabolic compensation
- Too much intense exercise suppresses immune system
- Muscles as endocrine organs
31:18 – Fasted vs. Fed Training
Ben’s recommendations:
- Fasted: Good for low-intensity cardio and walking
- Fed: Essential for strength training and hypertrophy
- Pre-workout nutrition should include essential amino acids and carbohydrates
- 25-30 grams of carbohydrate recommended
- Combination of glucose and fructose optimal for performance and recovery
34:05 – Creatine Supplementation
- Currently using 10 grams per day (up from traditional 5g recommendation)
- 10-20 grams showing benefits for cognitive function
- Timing less critical, but absorption improved with carbohydrates
- Ben takes during workout with essential amino acids and orange juice
- Peri-workout window optimal for nutrient absorption

Discussion of muscle mass as key factor in longevity:
- Can build muscle mass even in 50s, 60s, and 70s
- Requirements for muscle growth:
- Caloric surplus
- Adequate protein throughout day
- Multiple daily amino acid spikes with sufficient leucine
- Resistance training with progressive volume
- Mechanical tension and training near failure
- Adequate sleep for recovery
- Importance of hormone optimization (testosterone for men, estrogen/progesterone for women)
- Best strategy: maintain muscle mass going into 40s, 50s, 60s
40:04 – Muscle Loss with Aging
- Losing 3-8% muscle mass per decade after age 30
- Testosterone levels significantly decline by decade after 40
- Modern environmental and lifestyle factors affecting hormone levels
- Importance of addressing these factors systematically
42:01 – Individualized Approach
Dr. Barrett discusses the importance of not overwhelming clients:
- Body is only car you’ll ever have – requires maintenance
- Can’t give patients 15 things to do at once
- Importance of meeting people where they are
