This workshop provides a practical understanding of nutritional assessment for individuals undergoing GLP-1 receptor agonist therapy, emphasizing assessment before personalized diet planning. It covers medical history, dietary intake, anthropometry, body composition, and relevant biochemical markers to identify nutritional risks. Participants will learn to assess protein, fiber, fluid, vitamin, and mineral adequacy while focusing on preserving muscle mass during weight loss. The session also addresses common gastrointestinal side effects such as nausea, constipation, reflux, and reduced appetite. Practical nutrition strategies for hydration, meal portions, nutrient adequacy, and personalized dietary modifications will be discussed to support safe and effective GLP-1 therapy.
