The DAILY HACKS To End Inflammation & Increase Your LIFESPAN | Dr. Steven Gundry

Definition

Metabolic flexibility refers to the body's ability to switch between burning glucose and fat for energy. Lewis Howes explains that 50% of normal-weight individuals in the U.S. are metabolically inflexible, meaning they can't efficiently switch to burning fat when glucose is unavailable. This issue is even more pronounced in overweight and obese individuals, with 88% and 98.5% respectively being metabolically inflexible 1.

   

Insulin's Role

High insulin levels are a key factor in metabolic inflexibility. Insulin, a fat storage hormone, remains elevated in many people, preventing the release of fat from fat cells. Lewis Howes notes that this persistent high insulin level blocks fat burning, contributing to metabolic inflexibility 1.

   

Dietary Strategies

Improving metabolic flexibility involves strategic dietary and exercise practices. Lewis Howes suggests intermittent ketosis, which avoids the pitfalls of continuous ketosis that can lead to muscle wasting. He emphasizes the importance of a balanced approach to ketosis for optimal metabolic health 2.

   

Mitochondrial Health

Mitochondrial health is crucial for metabolic flexibility. Lewis Howes explains that mitochondria, the energy-producing organelles in cells, need to protect themselves by sometimes wasting fuel. This process, known as uncoupling, is essential for their survival and overall metabolic health 3.
