The script breaks down the biology: increased muscle phosphocreatine from supplementation leads to more creatinine production, while kidneys may still be filtering normally. It describes how this can trigger unnecessary repeat testing, medication changes, or specialist referrals if supplement use isnt disclosed. Cited randomized controlled trials show creatinine rises with creatine, but other kidney markers—especially cystatin C—remain normal, including in a two-year study; creatinine also returns to baseline after stopping. The key advice is to tell clinicians you take creatine and use cystatin C or direct testing when kidney function is in question, with caution for those with pre-existing kidney disease. 00:00 Creatine Blood Test Trap 01:09 Creatine to Creatinine Explained 02:56 Why eGFR Looks Worse 04:12 Real World Misdiagnosis Spiral 05:58 What Studies Actually Show 08:36 Safety Caveats and Kidney Disease 09:07 What to Tell Your Doctor 09:43 Cystatin C and Final Takeaways 11:00 Wrap Up and Disclaimer Gualano, B., Ugrinowitsch, C., Novaes, R.

Your Cholesterol Test Is Missing the Real Problem

Because LDL particle size varies, two people can share the same LDL-C while one has many more small, dense particles, increasing plaque and inflammation risk. He cites evidence from the Framingham Heart Study and hospital data showing many coronary artery disease patients present with acceptable LDL levels. He argues apolipoprotein B (ApoB), with one ApoB molecule per atherogenic particle, directly counts particle number and predicts cardiovascular risk even after accounting for LDL-C, and notes guidelines recognize ApoB as a target, especially in diabetes, high triglycerides, or metabolic syndrome. 00:00 Normal LDL Myth 00:59 What LDL Measures 01:34 Particle Size Problem 02:10 Evidence It Fails 02:50 Hospital Reality Check 03:49 ApoB Explained 04:28 ApoB Beats LDL 05:38 Who Should Test 06:25 Lowering ApoB 07:10 Key Takeaways 07:53 Final Wrap Up Cromwell, W.

He highlights common examples including diphenhydramine (Benadryl and many OTC sleep aids like Nytol/Unisom), hydroxyzine, oxybutynin, and older antidepressants like amitriptyline, noting risk is highest with higher dose, longer duration (including 3+ months), and especially when multiple anticholinergics are combined. Older adults (over 60) and those with memory concerns or family history may be most at risk. He advises not stopping prescriptions abruptly, reviewing all prescription and OTC products, asking a pharmacist to assess overall anticholinergic exposure, and discussing lower-risk alternatives with a doctor. 00:00 Hidden Dementia Risk 01:00 How Anticholinergics Work 02:18 Common Drugs Involved 03:26 Stacking Raises Risk 04:26 What Studies Show 05:40 Who Is Most Vulnerable 06:42 What To Do Next 07:29 Big Picture Brain Health 08:45 Pharmacist Conversation 08:56 Wrap Up Dmochowski, R.

He advises ignoring all front-of-pack claims and instead checking the legally required nutrition panel, focusing on added sugars (rather than total sugars) and sodium. He highlights common problem categories: drinks like smoothies, vitamin waters and sports drinks; canned soups and ready meals with high sodium; protein bars and drinks with 20–25g added sugar; low-fat and flavored yogurts that often replace fat with sugar; and salad dressings and sauces where sugar may be the first ingredient. He suggests choosing zero-added-sugar drinks, lower-sodium soups, whole-food protein sources, plain yogurt with added fruit, and simple dressings like olive oil and vinegar. 00:00 Health Foods Sugar Trap 00:52 Ignore Front Labels 01:34 Added Sugar Number 02:00 Sugary Wellness Drinks 03:24 Soup Sodium Shock 05:01 Protein Bar Pitfalls 06:10 Salad Dressing Sugar 07:20 Low Fat Yogurt Myth 09:14 Daily Pattern Problem 09:52 30 Second Label Check 10:16 Wrap Up And Next Yang, Q., Zhang, Z., Gregg, E.

Visceral Fat Doesn’t Stand a Chance in 90 Days With This

Get free weekly science-backed tips to feel better, live longer 👉 https://dradrianlaurence.substack.com/welcome [https://dradrianlaurence.substack.com/welcome] Lose Visceral Belly Fat in 90 Days (Without Cutting Calories or Endless Cardio) Family and Lifestyle Medicine doctor Adrian explains why cutting calories and doing lots of low-intensity cardio are poor first strategies for reducing visceral fat, which typically requires months of consistency rather than short diets. He outlines a 90-day plan with four priorities: stop using the scale as the main metric and track waist-to-height ratio instead (aiming to reduce risk when it’s above 0.5), fix sleep first (7–9 hours) to improve appetite hormones and reduce overeating, shift exercise toward moderate-to-high intensity aerobic work or interval training three times per week (with optional resistance training), and substantially reduce or stop alcohol because it pauses fat burning, adds calories, and worsens sleep. He notes food quality and protein matter but come after these foundations, and that blood markers often improve before waist measurements. 00:00 Why Cardio Fails Visceral Fat 00:57 Why 90 Days Matters 01:46 Ditch the Scale Metric 02:11 Waist to Height Ratio 02:52 Sleep as the Foundation 04:25 Train for Intensity 05:56 Alcohol and Belly Fat 08:02 What Not to Do 08:42 Food Strategy Hierarchy 09:33 90 Day Results and Markers 10:26 Keep Going and Wrap Up Chang, Y.-H., Yang, H.-Y., & Shun, S.-C.
