Getting fitter can reduce prostate cancer risk by 35%, study finds

A recent study linking even modest gains in cardiorespiratory fitness to a sharply lower risk of prostate and other cancers prompts both enthusiasm for exercise and skepticism about whether the data show causation or mere correlation. Commenters broaden the lens to long-term health more generally, weighing the relative importance of aerobic capacity, strength training, diet quality, sleep, stress management, and social connection, while noting how vague terms like “balanced diet” can obscure real trade-offs. Anecdotes of sustainable weight loss and fitness gains underscore that gradual, consistent lifestyle changes—rather than extreme or highly complex regimens—are both more realistic and likely beneficial.

Exercise, Fitness, and Prostate Cancer Risk

  • Many commenters take the study as another data point that “being fit” has broad benefits, including reduced prostate cancer risk.
  • Clarification: the study looked at changes in cardiorespiratory fitness (VO₂ max), not just weight loss.
  • Some confusion over “3% improvement per year”: one reading is “constant improvement,” another clarifies the paper grouped people into “≥3% increase, stable, or ≥3% decrease” over ~7 years, not necessarily 3% every year.
  • Several note the study shows an association between higher fitness and lower cancer incidence/mortality, not proven causation.

Indoor Climbing and Subculture

  • Climbers praise the sport for strength, endurance, and powerful exposure to fear in a relatively controlled-risk setting, claiming it improves personality and mental resilience.
  • Others find climbing boring, expensive, and socially off‑putting, describing an “alternative frat bro”/hipster vibe and performative behavior in gyms.

Measurement and Longevity Frameworks

  • VO₂ max and grip strength are discussed as key longevity markers (citing a popular longevity book).
  • Grip strength is seen as a useful population‑level proxy for overall strength but with clear outliers (e.g., climbers, endurance runners).
  • Some find recommended regimens (high weekly Zone 2 and Zone 5 cardio plus strength and mobility) effective but hard to fit into normal schedules.

Diet, Meat, and “Balanced” Eating

  • Broad agreement that a “balanced diet” and reduced ultra‑processed food are good, but what “balanced” means is heavily debated.
  • Disagreement over meat and saturated fat:
    • One side argues red meat and saturated fat increase disease risk, citing strong evidence.
    • Others distrust nutrition science, claim the evidence is weak or confounded, and emphasize evolutionary meat consumption and dose‑dependence.
  • Debate over whether fast food can ever fit into a truly healthy diet; some say realistic small amounts are fine, others say the ideal is zero.

Other Lifestyle Factors: Sleep, Stress, Social Life, Ejaculation

  • Social connection and sleep are repeatedly emphasized as critical but often under-discussed health factors.
  • Chronic stress is viewed as a major health risk; smoking is controversially mentioned as possibly reducing stress, but strong sample‑bias objections are raised.
  • Studies linking higher ejaculation frequency to lower prostate cancer risk are cited humorously but taken as suggestive.
  • One commenter shares a detailed, successful weight‑loss and lifestyle‑change story (more walking, diet changes, intermittent fasting, supplements) to reinforce that gradual, consistent efforts pay off.
