要是问生酮减肥对于身体哪个部位减脂效果最好？那就是肚子了。

生酮时，腰腹部的围度减小情况出现最早，从整体看也是瘦得最明显的地方。

随着生酮的持续进行，大腿和臀部的围度也会开始明显减小，瘦脸作用也会慢慢体现，内脏脂肪逐渐降低，最终达到完美的减脂效果。

1 为什么腹部脂肪不健康？

研究表明，肥胖或超重可能会增加患一系列严重慢性疾病的风险，如心血管疾病、某些癌症和2型糖尿病。

而我们携带脂肪的位置可能比携带多少脂肪更重要。

内脏脂肪是指腹部脂肪发生在你的肝脏，胃和肠周围的腹腔内。内脏脂肪会增加体内的炎症水平，并可能导致健康问题。如果你的腰围比较大，那它有更大的几率是内脏脂肪。

2 生酮如何减少腹部脂肪？

在饮食之外，还有其他因素会影响体重减轻和脂肪组织，例如遗传，压力等。

研究表明，身体脂肪的分布可以预测你患心脏病和其他疾病的风险。与那些把脂肪储存在其他地方的超重的人相比，腹部脂肪过多的人患健康问题的风险更高。

在高碳水化合物饮食中，你会不断增加胰岛素，它会抑制脂肪燃烧，鼓励你的身体保持你的脂肪储存。

生酮饮食会降低碳水化合物的摄入量，降低胰岛素水平。使用酮类的胰岛素和血糖水平较低，可以使燃烧储存的脂肪更容易、更有效。

在某些情况下，那些适应酮类的人燃烧的脂肪比其他人多10倍。

研究表明，与其他饮食相比，生酮饮食对减肥、减肥脂肪和腰围是有效的。

最近对12项研究的回顾显示，采用生酮饮食可以平均减轻22-34.3磅（约19.9-30.5斤）体重，腰围平均减少约5英寸。

导致腹部脂肪增加的罪魁祸首之一是添加糖，当你没有吃太多的碳水化合物，无论是在休息时还是在运动期间，你的身体都被迫燃烧脂肪作为燃料。

当您处于酮症的代谢状态时，产生的酮类物质也能自然地减少食欲和饥饿。渴望饥饿的欲望越少，你摄入的卡路里就越少，这就能促进体重的减轻和体脂的减少。
