An adequate protein intake prevents the loss of fat-free mass during weight loss. Laparoscopic sleeve gastrectomy (SG) jeopardizes protein intake due to post-operative dietary restriction and intolerance to protein-rich foods. The purpose of this study is to evaluate protein intake in the first three months after SG. We evaluated, 1 month and 3 months after surgery, 47 consecutive patients treated with SG. Protein intake, both from foods and from protein supplementation, was assessed through a weekly dietary record. Patients consumed 30.0 ± 10.2 g of protein/day on average from foods in the first month, with a significant increase to 34.9 ± 4.8 g of protein/day in the third month ( = 0.003). The use of protein supplementation significantly increased total protein intake to 42.3 ± 15.9 g protein/day ( < 0.001) in the first month and to 39.6 ± 14.2 g of protein/day ( = 0.002) in the third one. Compliance with supplement consumption was 63.8% in the first month and only 21.3% in the third month. In conclusion, both one and three months after SG, protein intake from foods was not sufficient. The use of modular supplements seems to have a significant impact on protein intake, but nevertheless it remains lower than recommended.
充足的蛋白质摄入可防止减肥过程中体脂的流失。腹腔镜袖状胃切除术（SG）由于术后饮食限制和对富含蛋白质的食物不耐受，会危及蛋白质的摄入。本研究的目的是评估 SG 术后三个月内的蛋白质摄入量。我们评估了 47 例连续接受 SG 治疗的患者，分别在术后 1 个月和 3 个月时进行评估。通过每周饮食记录评估蛋白质的摄入，包括食物和蛋白质补充剂。患者在术后第一个月平均从食物中摄入 30.0 ± 10.2 g 蛋白质，第三个月显著增加到 34.9 ± 4.8 g 蛋白质/天（=0.003）。补充蛋白质的使用使总蛋白质摄入量在第一个月显著增加到 42.3 ± 15.9 g 蛋白质/天（<0.001），第三个月增加到 39.6 ± 14.2 g 蛋白质/天（=0.002）。第一个月补充剂的使用依从率为 63.8%，而第三个月仅为 21.3%。总之，SG 术后一个月和三个月时，从食物中摄入的蛋白质都不足。使用模块式补充剂似乎对蛋白质的摄入有显著影响，但仍低于推荐量。
