Marc Bates, MPH, announced the release of his latest YouTube video exploring how the human body's ancient metabolic system conflicts with modern eating patterns. The video introduces the Randall cycle as a metabolic "traffic cop" that evolved for survival during food scarcity but now creates problems in today's food-abundant world.

The Randall cycle determines whether the body burns glucose or fat for energy. This system helped ancestors survive unpredictable food availability by efficiently switching between fuel sources during natural feast and famine cycles.

"Modern eating patterns create metabolic traffic jams when both carbs and fats are constantly present," Bates explains in the video. "The body cannot efficiently process either fuel type, leading to chronically elevated insulin and metabolic inflexibility."

Bates uses the analogy of a car engine damaged by mixed fuels to illustrate why simultaneously burning glucose and fat stresses cellular systems. This visualization helps viewers understand the metabolic inefficiency of constant food availability and frequent eating patterns.

The video outlines practical solutions for restoring metabolic flexibility. Bates recommends implementing intermittent fasting, incorporating regular movement, eating simpler meals that separate carbs and fats, and managing stress and sleep.

"Our bodies aren't broken," Bates emphasizes. "They're working exactly as designed for a different environment. We need to adapt our modern habits to better align with our evolutionary biology."
