Most Replayed Moment: Insulin Is The Reason You're Gaining Fat! How To Lower It Now

Podcast cover

The Diary Of A CEO with Steven Bartlett

High blood glucose levels trigger insulin release, which, when chronically elevated due to frequent carbohydrate consumption, leads to insulin resistance and the accumulation of toxic, inflammatory visceral fat around vital organs. This metabolic dysfunction often precedes a formal diabetes diagnosis by a decade, frequently manifesting as coronary artery disease. Fasting serves as a potent intervention to lower insulin levels, mobilize visceral fat, and stimulate autophagy—a cellular recycling process that repairs mitochondria and improves metabolic efficiency. Unlike simple calorie restriction, which can reduce muscle mass, fasting promotes the release of growth hormone and stem cells, facilitating tissue repair and improved cardiovascular health. Implementing structured fasting protocols, such as 18-6 time-restricted feeding or periodic longer fasts, alongside resistance training, helps restore natural metabolic flexibility and mitigates the inflammatory damage caused by modern, constant-feasting lifestyles.
