The 3 Hormones Controlling Your Stress, Cravings & Energy (Cortisol, Leptin, Ghrelin)

About this video

A one-minute introductory clip in which Brecka sets up cortisol, leptin and ghrelin as the three hormones governing stress, cravings and energy. He argues modern inputs — constant phone notifications, ultra-processed foods — blunt people’s ability to read their body’s signals, notes that acute cortisol spikes are necessary for survival despite cortisol’s bad reputation, and describes leptin and ghrelin as opposing appetite hormones whose interplay determines whether someone feels energized or exhausted and maintains weight or struggles with cravings. The clip ends as the full breakdown begins.

Key takeaways

• Brecka argues acute cortisol is a necessary survival response, not simply a ‘bad’ hormone
• He presents leptin and ghrelin as opposing appetite signals that jointly regulate hunger and energy storage
• Brecka claims constant notifications and ultra-processed foods interfere with reading the body’s own signals
