Ben Greenfield's body fat percentage consistently hovers at 5-7 percent despite a high caloric intake (3,000-3,500 calories daily), which he attributes to natural leanness rather than caloric restriction, and is rarely interviewed by someone with similar body composition metabolic characteristics

Ben Greenfield's workout protocol utilizes single-set-to-failure training 3 times per week using an ARX machine (2 horsepower eccentric load device) or Tonal wall-mounted machine, combined with Blood Flow Restriction training and a 21-minute VASPER (cold water circulation through BFR bands) HIIT session, with the remaining days focused on sauna, cold, breath work, walking and tennis/pickleball

Ben Greenfield's diet is largely low-carb Mediterranean including organic vegetables, fermented dairy, plant foods, organ meats, clean fish, bone broth, extra virgin olive oil, vinegar, and very dark chocolate, combined with an overnight intermittent fast of 12-16 hours, with occasional quarterly 3-5 day lower calorie or water fasts

Ben Greenfield uses vitamin IV cocktails a few times per month from Dr. Craig Conover's Fast Vitamin IVs company, and performs stem cell, exosome, and V-cell treatments 2-3 times per year with Dr. Matt Cook at BioRecept Medical, which he frames as an 'oil change' for the body

Braintree (founded by Johnson) was sold to PayPal in 2013 for approximately 800 million dollars, establishing Johnson's business background before his transition to longevity optimization and neural interface technology development

Ben Greenfield has practiced obstacle course racing and Iron Man Triathlon competitively for years but has since transitioned to primarily pickleball, walking, and occasional tennis for lower-intensity longevity-focused fitness rather than elite athletic performance

Ben Greenfield previously used a float tank (sensory deprivation tank) but discontinued due to difficult maintenance requirements, now using hyperbaric chamber for similar sensory isolation effects combined with oxygen therapy and light-sound meditation devices

Ben Greenfield weekly detoxification includes activated charcoal binders, steaming sessions (herbal steam applied to genital area), coffee enemas, and infrared sauna sweating (typically on Wednesdays) to 'clean out' the body weekly.

Kernel is also described as protective gear for the head during mountain biking excursions, serving a dual function as both a neural interface device and a protective helmet.

Ben Greenfield packs for travel using only carry-on luggage (one hard shell case and one expandable backpack) containing all necessary health protocol materials, and coordinates hotel/Airbnb deliveries of consistent Whole Foods orders (sardines, avocados, organic greens, dark chocolate, rotisserie chicken or salmon) to maintain protocol consistency while traveling

Ben Greenfield practices early morning waking (3:45-4:00 AM) following 6-7 hours of night sleep, utilizing the early morning hours for spiritual practice, meditation, and work preparation, then compensates with a 20-40 minute afternoon nap in either a hyperbaric chamber or on a PEMF mat using meditation, Yoga Nidra, or Brain Tap device

Ben Greenfield has high genetic predisposition to type 2 diabetes, family history of colon cancer and cardiovascular disease, and stable plaque accumulation from years of endurance sports (Iron Man Triathlon), requiring specific monitoring of diabetic markers, cardiovascular markers, and colonic health through targeted supplementation like red yeast rice, CoQ10, niacin, and butyrate focus

Ben Greenfield walks outdoors barefoot on earth for grounding/earthing exposure, receives regular sunlight exposure, consumes real food close to the planet as possible, avoids ultra-processed foods, and emphasizes these 'so-called non-negotiables' as accessible to anyone before pursuing specialized biohacks like laser therapies or wearable brain imaging
