The Journey

Greg's path to nutrition was far from conventional. At 27, he faced a life-altering challenge when diagnosed with cancer. That experience fundamentally shifted his perspective on health, wellness, and the profound impact of nutritional choices. Combined with his early exposure to the fast-food industry—where he witnessed firsthand the consequences of poor dietary habits—Greg became driven by a singular mission: to help others take back control of their health through informed, personalized nutrition.

This personal catalyst transformed into professional expertise. Over the past several years, Greg has built a reputation as one of the UK's most sought-after nutrition coaches, working with elite combat sports athletes, professional boxers, and general population clients pursuing serious health transformations.

Professional Expertise

Greg's work spans two complementary practice areas:

Philosophy

Greg rejects the one-size-fits-all approach to nutrition. He believes that sustainable health change requires:

• Personalization: Every client receives a bespoke plan tailored to their unique physiology, goals, preferences, and lifestyle constraints.
• Trust First: Before implementing any nutritional protocol, Greg builds a foundation of trust and understanding. He works on both the physical and psychological dimensions of eating, addressing emotional patterns, guilt, and relationship with food.
• Flexibility: Rather than rigid calorie counting, Greg monitors body composition and performance metrics, adjusting nutrition dynamically as progress evolves.
• Holistic Support: Nutrition is integrated within a broader lifestyle framework that includes sleep, stress management, mental wellbeing, and consistent coaching accountability.

"I don't work on nutrition first. You gain a client's trust, then you can implement your methods with 100% guarantee. That's why I'm different—because I work on the relationship before the protocol." — Greg Marriott

Results

Greg's clients report transformative outcomes:

• Professional athletes achieve peak physical condition for major competitions
• General clients lose significant weight while maintaining muscle and mental positivity
• Individuals overcome emotional eating patterns and build healthy relationships with food
• Clients develop the knowledge and confidence to manage their health independently long-term

What sets Greg apart is the consistency of results—not through willpower and restriction, but through sustainable behavior change, education, and genuine partnership with his clients.
