Overview
Middle-aged women with (overweight/)obesity who will begin or have begun GLP-1 medication use will be recruited to complete a 12-week diet intervention study. For 12-weeks, participants will continue to take their GLP-1 medication and may be provided with protein-rich foods to consume every day. Body composition, eating behavior, health, and well-being will be measured before and after the study.
Description
Middle-aged women with (overweight/)obesity who will begin or have begun GLP-1 medication use will be recruited to complete a 12-week, parallel-design, dietary protein intervention trial. The participants will be randomized into the following groups: GLP-1 ONLY (no dietary intervention) or GLP-1 + Protein. The GLP-1 only group will take/continue to take the respective GLP-1 medication as prescribed by their physician, whereas the GLP-1 + Protein group will take/continue to take the respective GLP-1 medication as prescribed by their physician but will be provided with a variety of protein-rich pork foods to yield 20 g of protein, twice daily, for 12 weeks, totaling \~40 g high quality protein. In addition, recipes will be provided to support the consumption of the protein-rich foods within the breakfast meal (required) and in other eating occasions.
