Excellent talk on all areas of diet, obesity and insulin resistance. I’ve tried many diets and after so much frustration I’ve found the low carb, healthy fat and moderate protein style of diet works well for me. Once you ditch the sugar and processed carbs the craving just goes away, makes healthy choices easier. I’ve lost 27lbs and now within 6 pounds of “normal” BMI. My fasting glucose is normally under 80-105 and have cut back on my BP med because my BP was actually getting too low….soon I’ll be off it entirely. I do intermittent fasting, so a short window of eating each day to heal my body and give it rest. I walk 30-60 min, Do weights and HIIT 3xs a week for each. I will always eat this way. I don’t discuss my diet with my doctor, just look at all the evidence for healing. Drs seem to encourage a higher amount of carbs than I feel is healthy for me. I also will never take a statin for cholesterol but mine is in an acceptable range with 51 HDL. This YouTube is best thing to follow to stay get healthy and stay that way. Thank you!

Dr. Morgan, this is just incredible, thank you very much for putting in all the hard work and sharing it with the rest of us! To better human lives 🥂

I have benefited greatly from watching lectures and reading a few books by the likes of Phinney, Lustig, Fung, Bikman, Goldkamp, Teicholz (and about twenty others). What a wonderful, well organized presentation ! Your YouTube presentations seem always informative and well organized. You are now on my list of people I follow closely. When you teach, those of you who have followed the formal education process to acquire knowledge in an orderly fashion, allow old goats like me (70), for whom time is growing shorter, to reverse engineer what is needed NOW. I would love to become an expert, but I doubt that will happen. I have learned some of the basics, but what you guys teach me increasingly fleshes out the bare bones and increases my confidence that I am closer to the right path. I'm not trying to be expert, I just want my ignorance to shrink somewhat. You all have led me to the water, now I'm in the process of trying to drink. Can't thank you enough.
PS: I have forwarded the link to my physical therapist daughter in Sweden.

Dr. Morgan, this is the most comprehensive and detailed description of IR . Thank you for all the great work and your passion to uncover/distill the science . You stand head and shoulders above all the fan boys of keto / vegan / lowcarb debate.

[josephneedhamjr]

The most well explained about insulin and how we're affected by resistance from high unnecessary carbs awesome. You seriously need funding every where to help the world...🥰

[colastyles]

I cannot express how helpful this is! Thank you so much, Dr
Morgan.

[tonyosime]

Thank you for such an excellent video. Very comprehensive, very engaging. You save many, many hours of searching and watching dozens of contradictory videos. I am going to re-watch your presentation to better appreciate all the gems of advice you provide.

[JRNurse]

I just had to tell you what an incredible job you did in making this video! Thank you! I’m a school nurse and I feel so sorry for our children! They have terrible lunches today at school! It’s almost all carbs whether it’s from the cafeteria or brought from home. We are all paying the price in health care today! Look at the people all around us…obesity is prevalent and yet preventable. 😢

I really like this presentation you did here. It needs to be shared world wide! Get the word out! Because I am someone who went to my doctor asking for help and before they even considered blood sugar or mediation to see if they could help with my weight gain, they waited until I was OVER WAIT in their eye, their being my insurance and whoever my doctor answers to. It's very frustrating. And now I'm over wait and having all these symptoms. I switched doctors and now am hoping I am on the right track to loosing weight by controlling my insulin!! I love listening to you and love all of the research and time you have put into these videos! Please keep going! You are helping so many understand this differently. And I hope someday doctors are more educated and the way doctors are taught changes and the guidelines can change too! ❤❤❤❤❤❤

There are only 3 sources of calories: fat, protein, and carbohydrates. Taking away fat, by definition, equals adding carbohydrates. Hello, insulin resistance!

[lorendisney]

I study Many videos on diabetes and yours is the best I have stage.5 kidney failure
