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.

Hey everyone, welcome to the Drive Podcast.

0:13.0

I'm your host, Peter Atia.

0:14.8

This podcast, my website, and my weekly newsletter, I'll focus on the goal of translating

0:18.7

the science of longevity into something accessible for everyone.

0:22.4

Our goal is to provide the best content in health and wellness, full stop, and we've

0:26.6

assembled a great team of analysts to make this happen.

0:29.4

If you enjoy this podcast, we've created a membership program that brings you far more

0:33.2

in-depth content if you want to take your knowledge of this space to the next level.

0:37.3

At the end of this episode, I'll explain what those benefits are, or if you want to learn

Now, without further delay, here's today's episode.

0:51.0

Welcome to a special episode of the Drive.

0:53.2

For this week's episodes, we're going to re-broadcast my conversation with Gerald Schumann,

0:57.6

which was originally released in December of 2020.

1:01.0

This episode is really a masterclass on insulin resistance.

1:04.4

In this, Jerry clarifies what insulin resistance means as it relates to muscle and liver and

1:08.8

the evolutionary reason for why it exists.

1:10.7

He goes into great depths from the mechanisms that lead to and resolve insulin resistance,

1:15.1

the clinical implications of these mechanisms, the role of diet, exercise, and pharmacologic

1:19.3

agents.

1:20.3

While this was one of our most technical episodes, it was also one of the most popular episodes

1:24.4

ever.
