124: What Is The Difference Between Glucose Intolerance and Insulin Resistance

In this episode, Dr. Steve explains the difference between insulin resistance and glucose intolerance, two common metabolic issues. He discusses how muscle health, diet, and insulin sensitivity impact glucose levels, offering practical advice on maintaining metabolic health. Learn how regular exercise, especially strength training, and proper nutrition can help prevent insulin resistance and improve glucose regulation.

 

[00:01 - 08:36] Understanding Insulin Resistance

Muscles use ATP from mitochondria to power the body.
Eating carbs increases glucose, triggering insulin to fuel muscles.
Insulin helps store glucose and amino acids in muscles for growth.
Aging reduces muscle mass, but exercise and nutrition can prevent this.

[08:37 - 18:45]The Role of Fat Cells

When muscles can't absorb glucose, fat cells store it and grow.

Overloaded fat cells become insulin resistant.

Large fat cells leak fatty acids into the blood, raising inflammation.

Chronic high insulin levels lead to diseases like type 2 diabetes.

[18:46 - 22:41] Insulin Resistance vs. Glucose Intolerance

High glucose and insulin levels occur when the body struggles to store glucose properly.

After eating carbohydrates, insulin is released to lower glucose levels, which is the body's natural response.

Glucose levels stay high, but the body may not produce enough insulin or respond efficiently to it.

The pancreas first releases stored insulin and then produces more as needed based on glucose levels.
