These 3 Hormones Control Everything About Your Weight and Stress! | TUH #220

About this video

Brecka explains three hormones he says govern stress, weight and appetite: cortisol, leptin and ghrelin. He argues acute cortisol is necessary and follows a daily rhythm, while chronic elevation is the problem, citing research he says supports mindfulness, exercise and brief time in nature for lowering baseline cortisol. He then describes leptin and ghrelin as opposing appetite signals, claims calorie restriction and poor sleep disrupt them, discusses leptin resistance as, in his telling, a driver of obesity, and presents consistent sleep, meal timing and whole foods as the foundation for hormonal balance.

Key takeaways

• Brecka claims chronic cortisol elevation, not acute spikes, is where harm occurs
• Brecka cites nature exposure as, he says, a measurable cortisol-lowering intervention
• Brecka argues leptin and ghrelin work in opposition to regulate hunger and fullness
• Brecka claims poor sleep disrupts all three hormones simultaneously
