Stavros Mastrogiannis is a sustainable weight loss coach and personal trainer with over 30 years of experience and 1,500+ clients. His approach flips the usual script: Stavros doesn't focus on dieting or willpower — he's the founder of Live Your Way Thin & Healthy and creator of the Body Reset Protocol, built on the idea that weight gain isn't the problem, it's a symptom of disrupted body systems.

His approach was shaped early, growing up in a small village in Greece where he watched elders stay naturally lean and healthy into their 80s and 90s — without dieting, calorie counting, or gym memberships. That observation became the foundation for his life's work: helping people reset their body's systems so lean and healthy becomes the natural outcome of living their life.

He's also the founder of the Lean & Healthy by Default Movement, a free public education platform sharing the truths about weight and health that the industry has little financial incentive to tell people.
