All protocols

Framed as a key controllable lever for cancer risk management and something to focus on rather than obsessing over ubiquitous environmental exposures.

Attia says they want to know ApoE status in everybody because of its role in Alzheimer's disease risk.

Recommended as the screening tool for colon cancer prevention because polyps can be seen on colonoscopy; screening should occur no later than age 40.

Described as the commonly used traumatic brain injury protocol: five 60-minute sessions per week at two atmospheres. For general longevity rather than acute TBI, Attia says the time would be better invested in exercise.

Mentioned together as omega-3 brain-health supplements they may still recommend because potential benefits may outweigh costs, though evidence is described as unimpressive.

Recommended as part of preserving type II fibers and aging well; ideally include training that involves jumping and landing to preserve explosiveness and braking capacity relevant to fall prevention.

One of Attia's pillars of strength training; emphasized for braking capacity and stepping down safely.

One of Attia's four exercise pillars for longevity and aging well. Example implementation: single-leg step-ups and very slow step-downs off a box for about 10 minutes, using a 2-second up / 4-second down tempo.

One of Attia's four exercise pillars for longevity; corresponds to zone 2 base-building.

Attia says he uses DBT as a regular part of therapy.

When making a mistake, immediately stop, imagine a close friend made it, and audibly speak to them kindly instead. As part of the exercise, Attia recorded the compassionate response on his phone and texted the audio to his therapist.

Maintain a healthy diet that includes sufficient vitamin A and lutein through food sources; examples given include dark green leafy vegetables (closest to raw or only lightly cooked), liver occasionally if desired, egg yolks that are not overly cooked, and fruits such as blueberries as a source of zeaxanthins.

If prescribed a prism lens for a slightly deviating eye, discuss with an ophthalmologist or optometrist whether exercises could address the issue without the prism, due to concern about progressive muscle weakening.

Rather than being overly reliant on corrective lenses, consider working with a weaker prescription.

Presented as acceptable from an EMF standpoint; the guest says he uses Bluetooth headphones and is not worried because the power levels are tiny and far below concerning ranges.

Cooling vests are cited as a way to expose yourself to cold and grow brown fat over about 10 days.

As temperatures cool heading into winter, intentionally wear less clothing to prepare for winter cold and improve cold adaptation; more broadly, avoid bundling yourself up all the time.

As temperatures warm heading into summer, intentionally wear more clothing to be a bit uncomfortably warm and improve heat adaptation.

For people whose hands hurt intensely in cold water, keep hands out for part of the exposure or dip them briefly and then remove them while keeping the rest of the body in.

Neoprene boots can reduce foot and ankle pain during cold exposure.

Avoid dunking your head during cold immersion, especially if you want to limit heat loss and afterdrop risk. Dunking the head can further reduce cerebral blood flow and increase core heat-loss rate by about 36% versus immersion up to the neck.

Wear during cold exposure, especially in windy outdoor conditions, to protect the ears/head, reduce dizziness or brain freeze, and help tolerate staying in for 1–2 minutes.

Insulating the head in sauna can make it easier to stay in longer by reducing the brain-driven urgency to exit.

Do not directly transfer adult protocols to children because of smaller body mass and faster heat loss; brief exposure only, with around 1 minute mentioned as a tolerable upper range in one study.

Do not keep the plunge at one very cold temperature all the time or rely on ice every session. Vary temperature up and down; even milder temperatures such as around 12°C water or 19°C cold air can still activate brown fat.

Keep mental training and visualization very brief, about 15 to 20 seconds, or sequences that can be completed in 15 seconds or less. Make visualizations sparse and simple rather than elaborate, and repeat the same short sequence over and over with high accuracy.

Name the skill or sub-skill you are visualizing using labels that match real-world training; use the same name or identity for the skill in both real-world practice and mental rehearsal.

Move your eyes in the direction of the imagined object or action, even behind closed eyelids, to recruit more of the relevant neural circuitry.

Perform about 50 to 75 repeats of the short mental sequence per session. Do as many repeats as fit into about a 15-second epoch when the skill is short enough, then rest for about 15 seconds before repeating.

Use mental training primarily for skills you can already execute successfully at least some of the time in the real world; it is best for improving speed, smoothness, frequency, and accuracy rather than creating a skill from zero. For language learning, pick a sentence you can already say, even slowly, and mentally rehearse it to improve accent, enunciation, smoothness, and fluidity.
