268. The New Science Behind the Keto Diet with Dr. Steven Gundry

Microbiome

The intricate relationship between our gut microbiome and mitochondria plays a crucial role in overall health. Steven R. Gundry explains that short-chain fatty acids, such as butyrate and acetate, produced by gut bacteria, can signal mitochondria to uncouple, similar to ketones 1. This uncoupling process is vital for mitochondrial health and energy production.

These are actually signaling molecules in and of themselves that signal our mitochondria to flourish, to protect themselves, to do repair work.

Additionally, Jeff Krasno and Steven discuss the importance of fermented foods, which provide prebiotics and postbiotics that support this gut-mitochondria communication 2.

   

Flexibility

Metabolic flexibility is essential for switching between burning carbohydrates and fats, yet many struggle with this transition. Steven R. Gundry highlights that a significant portion of the population lacks this flexibility, making it difficult to sustain a ketogenic diet 3. Insulin resistance exacerbates this issue, as elevated insulin levels prevent fat from being released as fuel 4.

Insulin is a fat storage hormone. But when insulin rises and you're trying to store fat, insulin doesn't want fat to come back out of fat stores.

This metabolic inflexibility often leads to the failure of ketogenic diets, as individuals cannot efficiently switch to burning fat for energy.
