    If I only saw this 3 years ago when I was working in a lab studying artificial sweeteners😂 it was a multi variable experiment where we gave the rats either sugar water, saccharin sweetened water or regular water (control). Within those groups there were high fat/ low fat diet groups. From what I remember, the rats that got the saccharin sweetened water were noticeably bigger at the end before uh... “sacrificing” them. There’s a reason I left the lab 😂 learned how difficult holding a 1kg rat was 🙄

    2012 Hank is my favorite. ❤😂 Who am I kidding? All Hanks are my favorite.

    Thank you so much for this. I've hit fifty, and my usual practice of maintaining my sugar intake hit a new snafu. It is good to know this information. Last month, I was telling my doctor the substitutes were increasing my sugar cravings. Now this video has explained this is true, confirming I'm not crazy, I can tackle and handle my sugar demands far better. Thank you again!
  • hey! i know this video is older but I've recently been told about how we still have an insulin response when using SOME artificial sweeteners. could you do a video on that and the repercussions of insulin in the bloodstream when there is no sugar to be dealt with?
  • @Beanskiiii
    Wow, I never new why they labeled gas unleaded. You learn something new everyday. Good video.
  • Dear Hank, you keep mentioning that fructose and glucose are chemically very similar. However in the context of metabolism, fructose and glucose are very different. Glucose is metabolised primarily with insulin , either into storage (fat) or glycogen for immediate use. However fructose can't. It is metabolised primarily by the liver, creating various metabolic byproducts. However, because fructose is so chemically similar to glucose, it can gum up the insulin pathways, causing the pancreas to work harder producing more insulin to metabolise the same amount of blood sugar load. In this way, both sucrose and HFCS are much harder on the liver and pancreas than rice, pasta or glucose syrup are, calorie for calorie . Can you please do a video about this metabolic difference? ( my husband and I are co-patreons)

    American: "Sixty nine teaspoons a day!" Europe:"No, six-to-nine teaspoons a day."
  • This morning out of the blue my 5 year old said "Let's watch SciShow." 👍
  • @JukesMcGee
    3:27 No way! I'm eating cap'n'crunch as he told me that! continues eating

    That moment where I feel proud for dropping soda... ...I mean, it was a mess and spilled everywhere, but at least it won't get to harm anyone.
  • This is exactly what you guys needed to do. addressing a bigger problem with smaller ideas that come together
  • Thank you for finally lighting the reality. I was back in the days repeatedly cursed out as a conspiracy theorist for claiming that "diet soda" drinking fat people get fatter by drinking "diet soda". ...+ touting along jelly beans, choco bars and various other snacks in their pockets :D
