[Formula diets for weight loss - chances and challenges].

Abstract

Introduction: Formula diets, through the use of industrially manufactured meal replacement products, lead to effective and rapid weight reduction and improvement in obesity-associated comorbidities. The specific composition of these meal replacement products simplifies the adherence to calorie goals and ensures the supply of essential nutrients during significant energy restriction. Despite numerous potential applications, evidence from randomized controlled studies, and simplicity in practical implementation, challenges persist. Monotony and social restrictions complicate adherence and acceptance. The use of formula diets for sustainable weight loss requires integration into a multimodal treatment approach with the goal of long-term changes in eating and activity behaviour. This includes accompanying nutritional counselling, promotion of physical activity, evaluation of adjuvant pharmacological or interventional therapies, as well as psychological support. The development of new incretin-based anti-obesity medications has opened another application field for formula products. There is optimization potential in expanding the product range and combining it with digital applications to enhance acceptance and reach a larger patient group.
