About

Sarah has spent over 8 years working exclusively in the field of metabolic dysfunction and insulin resistance. She earned her Nutritional Therapy diploma from the Institute for Optimum Nutrition and holds full BANT and CNHC registration. Her clinical approach centres on the Kraft Oral Insulin Assay — she was among the first BANT practitioners in the UK to integrate Kraft testing into her practice, having trained directly under experts in metabolic medicine. Sarah works with clients to map their postprandial insulin patterns, identify the earliest markers of metabolic dysfunction, and reverse type 2 diabetes risk through targeted dietary and lifestyle interventions. She is particularly experienced with clients who have PCOS, non-alcoholic fatty liver disease, and cardiometabolic syndrome.
