All protocols

Mentioned as important, especially when in a caloric deficit.

Very low carbohydrate intake was mentioned as part of the pattern associated with very low free testosterone in overtrained, calorie-deficient individuals doing a lot of vigorous exercise.

Stop the workout before complete exhaustion to preserve energy and vigor for the rest of the day.

Mentioned as the garlic compound that can help decrease conversion of carnitine/choline to TMAO.

Dates and raisins from Greece or Turkey were mentioned as potentially higher in boron.

Suggested as potentially helping growth hormone release because most growth hormone is released during sleep.

Very tight clothing was mentioned as a lifestyle factor to change in fertility consultations.

Mentioned as a better way than nicotine to optimize nicotinic receptor activity.

Long periods seated on a bike seat, especially with pressure on the perineum, were described as concerning for pelvic floor, continence, and impotence.

Use proper lifting form during heavy leg work and Valsalva-based lifting. If there is weakness or pathology, pelvic floor physical therapy may be needed. Kegels were mentioned as one of many exercises that can help, but not sufficient alone and excessive contraction can be problematic. Casual exercise like walking and stretching can help return blood flow to the area.

Alcohol significantly increases aromatase; recommendation was not more than 3 to 4 standard drinks every two weeks.

General recommendation to eliminate trans fats, except for naturally occurring trans omega-3 fats from grass-fed or finished ruminants.

Recommended in limited amounts because they are calorie dense, unless someone is trying to increase calories.

Small amounts were described as probably okay, but not excessive amounts.

PSA monitoring was discussed as important, with age-dependent reference ranges and special caution if using finasteride or dutasteride because they can halve PSA.

Mentioned as a topical antiandrogen option for hair loss.

Topical spironolactone was said to be systemically absorbed; males were specifically warned not to use it unless prescribed by a doctor.

Discussed as likely only minimally systemically absorbed and not affecting systemic DHT, making it a potentially preferable topical antiandrogen for hair loss.

Huberman reports turmeric crushed his DHT and vitality; framed as an anecdotal but strong personal avoidance.

Huberman says he avoids black pepper extract or bioperine because it is a 5-alpha reductase inhibitor and affects liver cytochromes.

Used to test both filtered and tap water, including for contaminants such as microplastics.

Use a water testing service and test both filtered water and tap water.

Added to his obstetrics avoidance list because of concern about phthalates.

Explicit caveat against an unsafe approach to peanut allergy exposure.

Do not trust wrist-worn trackers for energy expenditure; they often overestimate calories burned, with a cited meta-analysis showing 28% to 93% overestimation.

For intentional weight loss, weigh yourself every day first thing in the morning, ideally after urination and bowel movement, then use the weekly average and compare it to the next week's average rather than reacting to single-day fluctuations.

Track steps during dieting to monitor spontaneous activity and keep them from dropping; example given was maintaining 8,000 steps/day. If spontaneous activity falls, add about 15 to 30 minutes of cardio to maintain movement output.

Macro tracking is presented as a workable calorie-restriction strategy and personal method for body composition control.

Experiment with approaches like keto and omnivore phases to discover what is easiest and most sustainable for you.

When moving from ketogenic to higher-carb eating, transition gradually and systematically over about 4 to 8 weeks rather than abruptly.
