When I had trouble bending over to tie my shoes and I wasn't pregnant. When I hit about 35 I started having trouble with weight. The strange thing was to me, it wasn't that I was eating more then I used to, as a matter of fact I started eating less. When that didn't help I barely ate at all. Still I couldn't lose weight. What I didn't know was we start to lose muscle mass every decade beginning in our thirties, and I was a ripe 35. Muscles use up more calories than fat, so less muscle means a slower metabolism and the need for fewer calories, and the pounds stack on easier. My second problem was my narcolepsy. When you wake up after a nights sleep there is a release of adrenaline which prompts body and mind into action and helps burn off calories. Narcolepsy causes me to sleep on and off during the day, and as explained by my doctor (so if I have this wrong about adrenaline it is my doctors fault lol) I am not getting that adrenaline release because my bodies clock doesn't know if I am asleep or awake. He suggested in the morning to start exercising about 20 minutes to get that adrenaline rush, in the afternoon exercise about twenty minutes more for the same reason Dieting and exercising brought those pounds back down. I will say it is much harder in the winter for me then in the summer. Summer time I am naturally active. I ride bikes with my husband, swim, garden, mow about an acre of lawn. In the winter I can't ride, swim, garden, or mow, and I hate exercise I don't enjoy. Anyway the long answer to the defining moment but there it is just the same. According to the above context, choose the correct option to answer the following question. Question: Why was the narrator advised to exercise? Options: - because not getting enough adrenaline in the morning - because not getting enough adrenaline in winter - because not getting enough adrenaline at night - not enough information
A:
because not getting enough adrenaline in the morning
