Elyse Resch is a nutrition therapist, registered dietitian, certified eating disorder dietitian, and a health at every size (HAES) advocate. She is known for co-authoring the book "Intuitive Eating" along with Evelyn Tribole. The book, first published in the 1990s, helps readers to establish a healthy relationship with food by advocating for a non-diet approach and encouraging individuals to listen to their bodies' natural hunger signals instead of following external dieting rules or trends. Resch's work emphasizes self-care, body acceptance, and a balanced approach to nutrition, aiming to assist people in freeing themselves from chronic dieting and disordered eating patterns.
