All about Insulin and insulin resistance at an advanced level

A friend of mine was listening to this podcast and thought I might be interested. As many of you regulars know, I’m not much of a techie, but I thought some of you might appreciate this so I’m attaching it so that you know about it. I personally have not listened to the podcast and probably will not.

Gerald Shulman is a Professor of Medicine, Cellular & Molecular Physiology, and the Director of the Diabetes Research Center at Yale. His pioneering work on the use of advanced technologies to analyze metabolic flux within cells has greatly contributed to the understanding of insulin resistance and type 2 diabetes. In this episode, Gerald clarifies what insulin resistance means as it relates to the muscle and the liver, and the evolutionary reason for its existence. He goes into depth on mechanisms that lead to and resolve insulin resistance, like the role of diet, exercise, and pharmacological agents. As a bonus, Gerald concludes with insights into Metformin’s mechanism of action and its suitability as a longevity agent.
We discuss:
• Gerald’s background and interest in metabolism and insulin resistance (2:30);
• Insulin resistance as a root cause of chronic disease (6:30);
• How Gerald uses NMR to see inside cells (10:00);
• Defining and diagnosing insulin resistance and type 2 diabetes (17:15);
• The role of lipids in insulin resistance (29:15);
• Confirmation of glucose transport as the root problem in lipid-induced insulin resistance (38:15);
• The role of exercise in protecting against insulin resistance and fatty liver (48:00);
• Insulin resistance in the liver (1:05:00);
• The evolutionary explanation for insulin resistance—an important tool for surviving starvation (1:15:15);
• The critical role of gluconeogenesis, and how it’s regulated by insulin (1:20:30);
• Inflammation and body fat as contributing factors to insulin resistance (1:30:15);
• Treatment approaches for fatty liver and insulin resistance, and an exciting new pharmacological approach (1:39:15);
• Metformin’s mechanism of action and its suitability as a longevity agent (1:56:15); and
• More.


I can’t wait until I get to this part. This is the first I have seen that verifies my opinion that insulin resistance is an evolutionary mechanism to stave of famine. It allows enough individuals to have offspring. My hypothesis is the mechanism is triggered by chemical and enzymic changes in food as it ages.

BTW this would be good for both type 1 and 2 diabetics to listen. The proportion of people with insulin resistance that are type 1 is probably equal to the general population.

Thanks for the link. I can’t wait to read it.

It’s an audio pod cast

Thanks for the link @bostrav59 ! This is going to be my TDay diversion :microscope:
