So if you put these physiological processes to work, I'd hypothesize that it might be our increased intake of refined grains, sugars and starches that's driving this epidemic of obesity and diabetes, but through insulin resistance, you see, and not necessarily through just overeating and under-exercising.
所以如果把这些生理过程也列入考虑， 我认为是大量的不断摄入 精制谷物，糖类以及淀粉类食物导致了 肥胖症和糖尿病的流行， 但其病因是胰岛素抵抗症 而不是由于暴饮暴食以及缺乏运动。
