Petronella Ravenshear

Petronella Ravenshear established a clinic in London’s Chelsea, where for two decades she specialized in addressing weight loss, skin conditions, and digestive disorders. Her approach has consistently centered on the practical application of nutritional science to improve client health. She developed ‘The Human Being Diet’ (HBD) in response to a common issue among her clients: a lack of tangible results from various diet and exercise regimens. This program aims to reestablish the body’s long-term balance through fresh, nutrient-dense, minimally processed, and anti-inflammatory foods. Ravenshear’s methodology is also grounded in the principles of metabolic balance, focusing on how diet impacts hormones like insulin and cortisol, crucial for metabolic health and weight management.

The Human Being Diet, often referred to as ‘HBD’, is a structured three-month program that emphasizes ‘feasting and fasting’. It begins with a 16-day ‘Reset’ phase, which is oil, alcohol, sugar, and grain-free, designed for detoxification and to initiate changes in metabolic function. Following this initial intense phase, the program guides individuals into a sustainable eating pattern that prioritizes whole foods and strategic meal timing, with a minimum five-hour fast between meals to manage insulin levels and inflammation. Ravenshear’s work is further supported by her academic background, having studied at the Institute for Optimum Nutrition in London, the Natura Foundation, and The Institute for Functional Medicine. Her clinical experience and research combine to inform the practical application of her dietary recommendations, influencing a clientele that has included figures in fashion and celebrity circles. She relocated to Florida from London prior to the pandemic, continuing her work.

Ravenshear has authored ‘The Human Being Diet’, a book detailing her program. She frequently shares insights and guidance through various platforms, including interviews and podcasts, discussing topics such as health resets, the principles of ‘The Human Being Diet’, and strategies for optimal well-being. Her public engagement also includes discussions on making positive lifestyle changes. The program has garnered a significant following, with online communities sharing experiences and recipes related to the HBD.
