Nutrition expert Petronella Ravenshear has appointed Claire Etchell PR to handle the press and publicity for herself and for her practice Chelsea Nutrition. Petronella opened Chelsea Nutrition, in 2008 and central to Petronella’s ethos is that clients can adapt their lifestyle with easy and achievable new habits to enjoy a greater sense of wellbeing and to reach their target weight. She launched The Petronella Programme in 2017 which is based on the principles of metabolic balance but is more personalised using a specific blood test and functional testing, as well as the newly launched Map My Gut microbiome test, and DNA testing to help her clients.
