About Maggie Halloran
Maggie Halloran is a Tufts-trained Registered Dietitian with a PhD in Nutritional Sciences and over fifteen years of clinical and academic experience in weight regulation, metabolic adaptation, and the nutritional management of patients on GLP-1 receptor agonists.
She founded Clinical Nutrition Report in September 2025 with the goal of bringing evidence-graded, dietitian-authored coverage to the consumer nutrition app and AI tracking space — a market she viewed as dominated by affiliate content with little methodological scrutiny.
Maggie reviews and signs off on all clinical content touching pharmacotherapy, body composition, energy balance, and metabolic adaptation. She is the sole signatory on the publication’s editorial policy and methodology pages.
