It was investigated whether a home\u2010delivered, protein\u2010rich meal service improves protein intake relative to requirements within 3 weeks prior to surgery compared to usual care (UC).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This randomized controlled trial included adults (n = 126) with planned surgery performed at the orthopedics, urology, gynecology, or general surgery departments. The intervention group received 6 protein\u2010rich dishes per day for 3 weeks, and the control group sustained their usual diet. Dietary intake, nutrition status, hand grip strength, physical performance, and quality of life were assessed at baseline and after 3 weeks. Patient satisfaction was reported after 3 weeks, and data on complications and LOS were reported 30 days after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Protein intake relative to requirements significantly improved by 16%, and energy intake relative to requirements increased by 19% for the meal service, as compared with UC. The intervention group experienced significantly less stress with preparing meals and were more satisfied with the presentation of the meals than the control group. No significant effects of the intervention were detected on other secondary outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The home\u2010delivered, protein\u2010rich meal service was successfully implemented before surgery and improved protein and energy intake relative to requirements within 3 weeks while patient satisfaction maintained.
