摘要代谢综合征(metabolic syndrome, MS)是一种代谢紊乱性疾病，包括腹型肥胖、高血糖、血脂异常、高血压等，它反映了糖尿病、心血管疾病和其他病理状态的易感性。近年来，生酮饮食(ketogenic diet, KD)作为自然疗法之一，被证明有减重、降糖、调脂、改善胰岛素抵抗等作用，因而在代谢性疾病中的应用备受关注。越来越多的研究证据直接或间接地表明，KD或是MS的一种有效治疗方法。而如何安全有效实施KD及探索其治疗MS的生物化学机制将是今后临床研究的重点。

abstractsMetabolic syndrome(MS)is a kind of metabolic disorder, including abdominal obesity, hyperglycemia, dyslipidemia, hypertension, etc. It reflects susceptibility to diabetes, cardiovascular disease, and other pathological conditions. In recent years, ketogenic diet(KD), as one of the natural therapies, has been proved to be effective in reducing weight, lowering blood glucose, regulating lipid metabolism, and improving insulin resistance. Therefore, its application in metabolic diseases has attracted more attention. There is growing evidence demonstrating directly or indirectly that KD may be an effective treatment for MS. How to safely and effectively implement KD and explore the biochemical mechanism of KD in the treatment of MS will be the focus of clinical research in the future.
