Andrew and Abi Tunstall are the founders of SHAPEFIXER and passionate advocates for health, resilience, and personal transformation. With a multifaceted background as a nutritionist, elite athlete and former science teacher, Andrew combines professional expertise with personal experience to inspire others to overcome health challenges and live their best lives.

Andrew's Story

Andrew’s health journey is one of determination and defying the odds. Faced with the prospect of heart surgery and a hip replacement in his late fifties, Andrew declined both and instead turned to lifestyle and nutrition strategies. By making informed, science-backed decisions, Andrew reversed hip arthritis and reclaimed his ability to run, proving that the right approach can achieve remarkable results.

Professional Expertise

With a professional background in biology and biochemistry, Andrew’s scientific training has equipped him with a deep understanding of the human body and its needs. While he recognizes the role of medication in managing health, he firmly believes that diet and lifestyle adjustments are underutilized tools for combating, limiting, and even reversing metabolic diseases and the effects of aging. Through SHAPEFIXER, Andrew shares these insights to help others take control of their own health and well being.

Personal Achievements and Interests

Beyond his professional pursuits, Andrew has achieved international success as an elite athlete, demonstrating the importance of perseverance and goal-setting. His experiences in sport not only honed his physical abilities but also reinforced the mental discipline and resilience that he now teaches others.  As a former science teacher, he has a passion for educating and helping others understand complex topics in an accessible way. He is an avid learner, staying up-to-date with the latest research in nutrition and health science.
