10 Things I Avoid As An ER Doctor

In this video I talk about 10 everyday habits that quietly damage your health, metabolism, sleep, blood sugar, heart, lungs and long-term longevity. From vaping and alcohol to refined flour, poor sleep and ultra-processed foods, this video explains the science behind the modern lifestyle choices driving chronic disease and low energy. As I always say on this channel, our health is largely determined by the "insignificant" things we do every day (good and bad). In this video, I walk through the 10 things I personally avoid as an ER doctor, why I avoid them, what the evidence actually says, and which small changes make the biggest difference over decades rather than days. What you’ll learn: -Why vaping may not be as harmless as people think -The hidden metabolic damage caused by liquid sugar -Why constant snacking keeps insulin elevated -How poor sleep changes your hormones and decision-making -Why movement throughout the day matters more than one gym session -The truth about refined flour and “healthy” snack foods -Why circadian rhythm and sunlight may be one of the biggest health levers of all TIMESTAMPS 00:00 Introduction 01:00 Smoking and vaping 03:03 Regular alcohol 05:31 Liquid sugar 08:21 Constant snacking 10:16 Sitting for hours without movement 12:27 Poor sleep and chronic sleep deprivation 14:01 Refined flour products 15:45 “Healthy” snack foods 17:11 Seed-oil-heavy deep-fried fast food 18:47 Living entirely indoors 21:16 Pulling it together REFERENCES Association of E-Cigarette Use With Respiratory Disease Among Adults: A Longitudinal Analysis — https://pubmed.ncbi.nlm.nih.gov/31859...
