研究目的:

研究旨在针对使用抗肥胖药物治疗的门诊肥胖患者,探讨在治疗初期通过液体化乳清蛋白口服营养补充,对减重质量(更多保留肌肉,更多减去脂肪)、膳食蛋白摄入达标率及胃肠道耐受性的影响,并探索其对肌肉量、体脂率及基础代谢的潜在作用机制。 以干预8周后肌肉量的变化为主要终点,分析液体蛋白补充相比标准高蛋白膳食在抑制去脂体重丢失、维持基础代谢方面的优势。观察蛋白质补充对膳食质量的提升效果。 通过计算膳食蛋白质摄入达标率及优质蛋白质比例,评估乳清蛋白干预是否能有效克服用药初期因胃肠道反应和食欲下降导致的蛋白质摄入不足,提升整体膳食结构。比较两组在胃肠道不良反应方面的差异。 探讨液体化乳清蛋白补充是否在减轻恶心、腹胀、胃排空延迟等症状方面优于单纯高蛋白膳食。利用人体成分分析仪和代谢车,分析静息能量消耗及宏量营养素氧化底物的变化,从能量代谢角度揭示早期蛋白质营养干预对预防肌肉丢失和代谢下降的可能机制。 研究旨在为抗肥胖药物治疗初期的营养管理提供循证依据,优化个体化营养支持策略。  

Objectives of Study:

This study aims to investigate the effects of 0......oral liquid whey protein supplementation during the early phase of anti-obesity pharmacotherapy in outpatient obese patients on weight loss quality (muscle preservation and fat reduction), dietary protein intake compliance, and gastrointestinal tolerability, and to explore its potential mechanisms on muscle mass, body fat percentage, and resting energy expenditure.The primary outcome is the change in muscle mass after 8 weeks intervention. We will compare liquid protein supplementation with standard high-protein diets in preventing lean body mass loss and maintaining resting energy expenditure. The study will also evaluate whether whey protein improves dietary quality by increasing protein intake compliance and the proportion of high-quality protein, and whether it alleviates gastrointestinal symptoms (nausea, bloating, delayed gastric emptying). Body composition and resting energy expenditure will be measured to explore the metabolic mechanisms underlying the prevention of muscle loss and metabolic decline.This research aims to provide evidence-based guidance for early nutritional management in anti-obesity pharmacotherapy and to optimize individualized nutrition support strategies.+..
