It’s the low fat, very high carbohydrate diet that we’ve been eating for the last 40 years, which raises levels of the hormone insulin and programs fat cells to go into calorie storage overdrive. Ilike to think of insulin as the ultimate fat cell fertilizer.
是近40年来我们的低脂肪但碳水化合物非常高的饮食，它会提高胰岛素的水平，促使脂肪细胞过度储存热量。我喜欢把胰岛素称为脂肪细胞的首要增肥剂。

insulin胰岛素

When someone with Type 1 diabetes first comes to attention, their blood sugar is high because they can’t make enough insulin.They invariably have lost weight. They may be eating 5,000 calories a day, and they’re still losing weight. You can’t gain weight without insulin. The opposite is also true. If you give someone with diabetes too much insulin, they will inevitably gain weight. Insulin programs the body to store calories, and most of those calories get stored in the fat cells. If you’ve got too much insulin, you’regoing to store too many calories. This has been very well established scientifically.
当I型糖尿病刚刚出现时，病患的身体因为无法制造出足够的胰岛素，血糖总是很高。他们几乎无一例外都非常消瘦。虽然他们每天可摄入多达5000卡路里的热量，体重仍在不断地减轻。没有足够的胰岛素，你就长不胖。反之亦然。要是你给某个糖尿病患者注射了过量的胰岛素，他就会不可避免地增加体重。胰岛素促使身体存储热量，这些热量大多会以脂肪的形式储存在脂肪细胞里。如果你体内的胰岛素过多，你就会储存过多的热量。这些都已经得到了科学的充分证实。

The quickest way to lower insulin is to cut back on processed carbohydrates andto get the right balance of protein and fat in your diet.A high fat diet is really the fastest way to shift metabolism. It lowers insulin, calms fatcells down and gets people out of the cycle of hunger, craving and overeating.
降低胰岛素的最快办法是少吃经加工的碳水化合物，并均衡摄入蛋白质和脂肪。其实，高脂肪饮食是改变新陈代谢的最迅速的方法。它可以降低胰岛素水平，让脂肪细胞不再忙于囤积脂肪，人就摆脱了“饥饿—食欲—暴饮暴食”的怪圈。
【经典句式】
lower降低
cut back on降低
processed carbohydrate经加工的碳水化合物
get the right balance of均衡
protein蛋白质
diet饮食
shift改变
cycle循环
crave渴望
overeat暴饮暴食
Until we address the underlying drivers of weightgain – which are fat cells stuck in calorie storage overdrive – we are going to be in a battle between mind and metabolism that we just can’t win. Cutting back on calories won’t do it. That doesn’t change biology. To change biology, you have to change the kinds of foods you’re eating.
脂肪细胞过度囤积热量是我们体重增加的根本原因，如果不能解决这个问题，我们就注定要在意志与新陈代谢之间的战斗中一败涂地。减少热量摄入达不到这个目标，它不会改变你的生理状态;而要改变生理状态，你必须改变你的食物种类。
【经典句式】
address解决
weight gain体重增加
a battle between … and … …和…的斗争
metabolism新陈代谢
cut back on降低

the underlying drivers of………的根本原因
… won’t do it. ……不会起作用。
