Dr Benjamin Bikman, researcher specializing in insulin and metabolic health, does a layman's level deep dive into insulin and insulin resistance and its effect on the body. Deep dive covering many years of research but explained on a level anyone can understand it and what effects it has on us. An excellent presentation. Hardly any nerdy technical jargon but explanation in common language.

Any diabetic it is a must watch. Any pre diabetic it is a must watch. Anyone carrying ten or more extra pounds as fat it is a must watch. Anyone who wants to prevent any of the three previous problems it is a must watch.

Taking some medications for the above problems?..........you guessed it, it is a must watch.

Here is a bonus one by Bikman I am watching right now. Any of the video interviews or presentations with him are worth watching. Here he is interviewed by a medical doctor. Good discussion between the two.

Thermodynamics talked about at around 28 or 30 minutes. Some new stuff I have never heard around minute 50 about high insulin levels signal the liver to create saturated fat out of carbohydrates. Vegetable oils around 1:18.
