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。
【经典句式】

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。
