The prevalence of overweight and obesity has continued to increase globally, and one-size-fits-all dietary recommendations may not be suitable for different individual characteristics. A personalized nutrition intervention may be a potential solution. This review aims to evaluate the effects of the technology-delivered personalized nutrition intervention on energy, fat, vegetable, and fruit intakes among adults with overweight and obesity. A three-step comprehensive search strategy was performed from 10 databases and seven clinical registries in published and unpublished trials. A total of 46 randomized controlled trials (RCTs) involving 19,670 adults with overweight and obesity from 14 countries are included. Subgroup and meta-regression analyses were conducted. Meta-analyses showed a reduction of energy intake (−128.05, 95% CI: −197.08, −59.01) and fat intake (−1.81% energy/days, 95% CI: −3.38, −0.24, and −0.19 scores, 95% CI: −0.40, 0.02) in the intervention compared with the comparator. Significant improvements in vegetable and fruit intakes with 0.12–0.15 servings/day were observed in the intervention. Combined one- and two-way interactions had a greater effect on energy intake reduction compared with their counterparts. Meta-regression analyses revealed that no significant covariates were found. Given that the certainty of the evidence was rated as low or very low, further well-designed RCTs with long-term follow-up are warranted.

技术对超重和肥胖成人饮食结果进行个性化营养干预：系统评价、荟萃分析和荟萃回归

全球超重和肥胖的患病率持续增加，一刀切的饮食建议可能并不适合不同的个体特征。个性化营养干预可能是一个潜在的解决方案。本综述旨在评估技术提供的个性化营养干预对超重和肥胖成年人的能量、脂肪、蔬菜和水果摄入量的影响。在已发表和未发表的试验中，对 10 个数据库和 7 个临床登记处执行了三步综合检索策略。共纳入 46 项随机对照试验 (RCT)，涉及来自 14 个国家的 19,670 名超重和肥胖成年人。进行了亚组和荟萃回归分析。荟萃分析显示能量摄入量（-128.05，95% CI：-197.08，-59.01）和脂肪摄入量（-1.81%能量/天，95% CI：-3.38，-0.24和-0.19分数，95与对照组相比，干预组的 % CI：-0.40，0.02）。干预期间观察到蔬菜和水果摄入量显着改善，每天 0.12-0.15 份。与同行相比，单向和双向相互作用的结合对减少能量摄入有更大的影响。荟萃回归分析显示，没有发现显着的协变量。鉴于证据的确定性被评为低或极低，有必要进一步精心设计并进行长期随访的随机对照试验。
