首先，我们先来了解一下GI是何方妖孽！GI =（Glycemic Index）“血糖生成指数”——是反映食物引起人体血糖升高程度的指标，是人体进食后机体血糖生成的应答状况。
低GI饮食碰上减肥纯属误打误撞。众所周知，关于健康饮食至今并没有准确定论。怎样的饮食是健康的，什么样的生活方式是有益的，不同的方式各会带来怎样的后果？科学至今无法给出一个精准的数值来指导我们的生活。所以，低GI饮食的研究显然并不始于朴素的减肥目标。血糖生成指数的研究开始是为了更好的指导糖尿病人的饮食，使病人的血糖可以得到良好的控制。
血糖生成指数（GI）又是如何跟减肥扯上关系的呢？难道得了糖尿病有利于减肥？！让我们先来回顾一下糖尿病人的典型特征：“三多一少”即多饮、多尿、多食和体重减轻。划重点！划重点！！多食！体重减轻！！是不是发现了什么不可告人的秘密！
骨灰级减肥粉当初听到这句话时，两眼全是星星啊~拉着同桌的手一副苍天有眼的表情激动地说“我们一起去得糖尿病吧！”啊呸！回归理智的小编告诉大家，切不可有这般心思！健健康康最最最重要！！！
让我们来深入分析一下导致糖尿病患者多食而体重减轻的原因！首先，糖尿病的发病原因在于胰岛素分泌不足或生理功能缺陷导致的血糖浓度过高导致肾小管不能重新收所有滤过的葡萄糖而导致糖尿。正常人进食后血糖升高进而刺激胰岛素的分泌，使得葡萄糖得以被利用从而降低血糖浓度。说到这里不得不小声bb一句：虽然胰岛素责任重大，我还是很讨厌它。这就要说到胰岛素的生物学功能了，简单概括一句：胰岛素是一个全面促进合成的激素。在脂肪的合成作用上功不可没，同时这家伙还抑制脂肪动员，不让人家消耗掉！
所以，低GI 饮食减肥的关键就在于减少血糖波动对于胰岛素分泌的刺激，从而减少胰岛素的分泌，使得脂肪动员起来更容易。
那么，这种饮食方式的减肥效果到底如何呢？首先不要妄想它会迅速消瘦，科学告诉我们：所以在极短时间内的体重大幅度减轻往往伴有疾病的倾向！包括精神和身体两方面。牺牲健康代价太大，建议不要尝试。生命只有一次，如果动了这个念头记得找个心理医生聊一聊，美丽固然重要，但要学会爱自己！其次，没错，它确实有用，效果不错。有心的同志们可以尝试，配合清淡饮食效果更佳哦~（咸的食物可以刺激味觉，咀嚼会让你越来越有食欲，这就是为什么明明不饿吃两口就越吃越想吃的原因·····）（效果亲测有用，配合一定运动。）
