Exercise is remended for people mitments, such as family and ing clear that when we eat in relation to exercise could be important for this insulin response.锻炼带给健康的一个主要好处是能改善我们对胰岛素的反应，而且我们能更好地控制血糖水平，即使我们看不到这种变化。现在我们清楚地知道吃饭和锻炼的顺序可能对这种胰岛素反应有重要影响。
Our study looked at the responses to six weeks of exercise, which was supervised cycling for 50 minutes, three times a week. In one group, overweight or obese men exercised before breakfast (fasted state) and showed an improved insulin response after the training. That is, they had to produce less insulin to control their blood sugar levels.我们的研究观察了锻炼六周的反应，每周三次监测骑车50分钟的反应。在一群人中，超重或肥胖的男人在早饭前锻炼（禁食状态），锻炼后的胰岛素反应有所提高。也就是说他们必须减少胰岛素的分泌来控制血糖水平。This suggests that they had a lower risk of diseases such as type 2 diabetes after the training. But the men who performed the same exercise after eating breakfast did not show an improved blood insulin response.这表明他们锻炼后患二型糖尿病等疾病的风险更低，但早饭后进行同等锻炼的人血液胰岛素反应没有改善。The men who exercised before breakfast also burned about double the amount of fat during exercise than the group who exercised after breakfast. Current evidence suggests that this increased fat burning during exercise may explain why that group showed improved health benefits.早饭前锻炼的人在锻炼期间燃烧的脂肪量也是早饭后锻炼的人的二倍。目前的证据显示锻炼期间增加的脂肪燃烧量能解释为什么这群人的锻炼对健康更有好处。
