Actively work to achieve and maintain a high VO2 max, high muscle mass, and high muscle strength, as the data strongly indicate these are crucial for increasing lifespan and improving quality of life. Disregarding these foundational elements is considered irresponsible due to the overwhelming evidence.
Be willing to change your beliefs and practices when confronted with new, compelling scientific data, as this is fundamental to a scientific mindset rather than advocacy. Peter’s own views on various topics have evolved over time with new evidence.
Prioritize foundational exercise, including improving VO2 max, muscle mass, and strength, before considering numerous supplements for longevity. These exercise metrics are far more potent predictors of lifespan than many other health markers.
Recognize that weight loss fundamentally results from consuming fewer calories or expending more energy, not from a ‘magical’ metabolic effect of specific macronutrient ratios if calorie intake is truly equal. If weight changes occur on an isocaloric diet, it’s likely due to unacknowledged changes in intake or expenditure.
Avoid labeling sugar as a simple ‘poison,’ and instead consider its biochemical effects in terms of dose, frequency, and individual metabolic conditions. The impact of sugar is highly dependent on context, such as overall diet and activity levels.
Engage in regular exercise for significant improvements in physical, cognitive, and emotional quality of life, even if lifespan benefits were absent. The profound impact on health span makes exercise undoubtedly worthwhile.
Exercise caution with long-term fasting protocols, as they can lead to significant muscle loss that is difficult to regain. Peter personally stopped his extended fasting regimen due to substantial muscle depletion.
Do not rely on resveratrol for health benefits or longevity, as the evidence suggests it is ineffective and falls into the ’nonsense’ category. Peter does not take resveratrol due to a lack of belief in its value.
Do not take NAD precursors (NR, NMN) for geroprotective benefits, as the current evidence places them in the ’noise’ category for this purpose. Peter does not take these compounds due to low confidence in their efficacy for extending life.
Consider incorporating Blood Flow Restriction (BFR) training, especially with lighter weights and higher reps, to achieve superior strength and muscle hypertrophy. It is particularly useful during injury rehabilitation or as ‘finishers’ in a workout routine.
Do not take rapamycin without a deep understanding of its risks, probabilities, and uncertainties, and ideally with a physician who can guide you through that understanding. Peter views it as irresponsible to prescribe it without this level of patient engagement.
Exercise extreme caution and skepticism when seeking stem cell treatments, especially for conditions like osteoarthritis, due to the lack of consistent data and the prevalence of marketing over scientific evidence. The field suffers from a lack of uniform protocols and regulatory oversight.
Be aware that liquid sugar consumption can increase appetite and lead to higher overall caloric intake, even more so than solid forms of sugar. Prioritize consuming fructose in the form of whole fruit rather than processed sugars or sugary drinks.
Utilize a framework that assesses whether you are overnourished or under-nourished (body fat, visceral fat), adequately muscled or under-muscled (fat-free mass index, appendicular lean mass index), and metabolically healthy or unhealthy. This assessment provides a holistic view to inform personalized training and dietary strategies.
If you have Non-Alcoholic Fatty Liver Disease (NAFLD), avoid alcohol and limit fructose consumption to mild amounts from whole fruit. While evidence is still developing, these recommendations aim to reduce caloric intake and promote weight loss, which is beneficial for NAFLD.
If you are struggling with glycemic control or body weight and consume many artificial sweeteners, eliminate them and replace them with water or unsweetened beverages. Do not substitute them with full-sugar options, as this could lead to worse outcomes due to increased caloric intake.
If consuming a diet high in red meat (especially processed), ensure adequate intake of vegetables and insoluble fiber to mitigate potential cancer risks. The observed associations between high red meat consumption and cancer may be more related to the displacement of nutritious foods than the meat itself.
Consider chewing gum with xylitol for potential dental health benefits, specifically for its positive impact on the enamel of teeth. Peter personally uses xylitol gum for this reason.
