Anti-Aging Expert: Stop Touching Receipts Immediately! The Fast Way To Shrink Visceral Fat!

Anti-aging scientist Rhonda Patrick explains visceral fat, endocrine-disrupting plastics, the supplements that slow aging, and why vigorous exercise beats step counts.

Anti-Aging Expert: Stop Touching Receipts Immediately! The Fast Way To Shrink Visceral Fat!
The guest

Dr. Rhonda Patrick — Biomedical scientist and anti-aging researcher who runs the Found My Fitness podcast and newsletter. She translates cutting-edge longevity and metabolic-health studies into practical advice.

The gist

Steven Bartlett and Dr. Rhonda Patrick dig into visceral fat: what it is, why it doubles early-mortality risk, and how sleep loss, caloric excess, stress and alcohol drive it. They walk through Rhonda's framework of 'peak span' (staying within 90% of peak function) and the toll of endocrine-disrupting chemicals like BPA, phthalates and PFAS found in plastics, receipts, non-stick pans and packaging. A kitchen tour flags black plastic, canned soup, plastic utensils and bottled water as exposure sources. The back half covers Rhonda's supplement stack (omega-3, vitamin D3, multivitamin, creatine, magnesium, curcumin, urolithin A, glutamine), fasting and ketones, updated exercise guidelines favoring short vigorous bursts, the dangers of being sedentary, and a balanced look at GLP-1 weight-loss drugs.

Big reveals

  • Visceral fat doubles your risk of early mortality and raises metastatic cancer risk by 44%.
  • Healthy young men sleeping 4 hours a night for two weeks gained 11% visceral fat with no change on the scale.
  • Adolescent boys with the highest BPA levels had 50% lower testosterone than those with the lowest.
  • Patrick says don't touch receipts: thermal paper is coated in BPA and hand lotion drives it into the bloodstream ~100x more.
  • A consumer study found nearly all creatine gummies tested contained essentially no creatine.
  • New accelerometer data shows one minute of vigorous exercise can equal 4-10 minutes of moderate activity for cutting mortality.
  • Most people regain weight after stopping GLP-1 drugs as hunger returns 'with a vengeance.'
  • A study found 83% of AI users couldn't recall a passage they'd written with AI help; brain connectivity nearly halved.

Things worth remembering

  • Stop eating 3 hours before bed; eating late activates the sympathetic nervous system and fragments sleep.
  • Cooked-then-cooled rice or potato becomes resistant starch, good for the gut and shown to help sleep.
  • Resistance training barely moves visceral fat; aerobic, vigorous exercise (running, cycling, swimming) does.
  • Sulforaphane from broccoli sprouts activates phase-2 enzymes that help the body excrete BPA in urine.
  • Glass bottled water can carry more microplastics than plastic, from polymer paint on the lids.
  • Vitamin D3 supplementation slowed biological aging by almost 2 years in deficient people in a large study.
  • Creatine isn't just for muscle: ~10g/day raises brain creatine and Patrick calls it a daily 'game changer.'
  • Urolithin A clears damaged mitochondria (mitophagy) and extended lifespan ~20% in mice.
  • Women doing just 3.5 minutes of vigorous activity a day lowered cancer risk by 40%.
  • Sitting is an independent risk factor for disease, especially cancer, even if you exercise.
