One of the best videos about this subjects I have ever seen. A lot of people are obsessed with their blood sugar and tell people 120 mg/dl is deadly.

This video was outstanding. I began wearing a CGM after a T2 diagnosis. I moved to a low carb diet and have seen my A1C drop from 9.5 to 5.2 and lost 50lbs. I continue to wear a CGM to hold myself accountable in managing glucose spikes. I have been using 160 as my definition of a spike and focus managing post meal increases to 160 or below. I really appreciate your time educating us with facts based upon science.

Great video! I despise all these fear-mongering influencers and "doctors". It's so irresponsible and partly even dangerous. And then people copy these weird and silly arguments, share them on social media and with friends and contribute. So thank you for doing what you're doing!

[BartBVanBockstaele]

Another top-notch presentation. Highly recommended. I really love Mario's dispassionate no-nonsense presentation style as well as the high level of the information he presents.

[sahomd]

Academic-level information presented in a clear, understandable way!

[AbsenceLacksNothing]

Thanks Mario. I wish the folks at ZOE were similarly clear about what exactly we should be concerned about and what we shouldn’t. I hope they invite you to do a ZOE podcast soon and you can put them straight. Although something tells me that your message might actually cost them because their low level fear-mongering is a significant source of revenue for the ZOE brand. More power to you. Danke aus Schottland!

Many thanks for these useful facts, Mario!
You remain the best educator in this field to me and many more like me . Keep it we are supportive 🙏🏼

[lorenzoucce]

one of the best video on the internet, absolutely well explained and as a scientist, I appreciate all the data and very well presented data!

very well done!!!

[DrLeonardoAydos]

Like the new scenario! Amazing video as always

[shootitamboo]

👏👏 best talk on this topic. Congratulations

[MaryRaymond-cgwn]

As always, Thank you Mario! You have placed definitive cutoff readings so frequently presented within an understandable context but retained an awareness of their relevance. It is not real easy to work out personal glucose tolerance but you have removed some of the angst by providing a way forward. Cheers

[olgabaeva]

Thanks a lot for this valuable information! Glad that I found your channel

Thanks Mario for another superb balanced video based on science. I found one study based on oggt that suggested 1hr > 155 could be predictive for diabetes ( jcem 1hr postload hyperglycaemia 2018 fiorentino ...link wont upload) would be grateful for your views on whether this could extend to food. Thank you again for all your work.

Nice to hear from you, you have such a good quality content 🤗

[inasbriek]

Thank you so much for this informativ video. I have missed your Videos so much. You have said, that after a low carb diet, we should integrate more carbs to restore our insulin respond. Could you explain why?

[Roberto-cggr]

Better test of diabetes is measuring insulin. HOMA IR or Kraft insulin Assay Test. Early detection is better than cure. Hyperinsulinimia even if blood sugar thresholds are still normal. Definition of diabetes should change

[sherrygaley]

I’d like to see you do a video about the long-term 22:01 health risks of someone who has pre diabetes for say 5 plus years- An A1C of 5.7 to 6.1 for example. This person has higher fasting blood sugars - say 5.7 to 6.3 - but no spikes above 7.8.

[rajeshtanwar]

Objective and scientific knowledge 🎉❤🎉❤

[ruthe]

Excellent video! Thank you for disseminating evidence based information!

[monikakress]

I am one of those otherwise healthy people who wore a CGM for a month. I follow a predominantly plant-based diet. My glucose levels would “spike” every time I ate anything. I could have avoided spikes by swapping my fruit and beans for beef jerky and hard boiled eggs. I’ll stick with my plants and take my chances!
