Changes in dietary nutrient intakes at 6 and 12 months following bariatric surgery in a Chinese observational cohort.

ABSTRACT: Bariatric surgery (BS) effectively manages severe obesity, but postoperative dietary restrictions often lead to nutrient deficiencies, particularly in the first year. This study evaluated dietary intake and serum nutrient status at 6 and 12 months post-BS in 133 patients (sleeve gastrectomy/gastric bypass, 2022-2023). Nutritional assessments were conducted using 24-hour dietary recall, comparing results with the Guidelines for Medical Nutritional Treatment of Overweight/Obesity in China (2021). Total energy intake increased significantly from 6 to 12 months (116.2 ± 433.1 kcal/d, P = 0.02). Carbohydrate contribution rose by 3.0 ± 13.6 energy percentage (en%, P = 0.01), while fat (-1.6 ± 8.9 en%, P = 0.04) and protein (-1.4 ± 6.3 en%, P = 0.01) contributions decreased.
