How many rest days should I take between runs?

I wanted to know how many days of rest is recommended between workouts. I heard it was three days on to one day off...is this enough? I workout on a treadmill for 50 minutes every day and have for the last 14 months. I was not aware of how rest played a very important role until I recently read a brief article on it. I guess my question is, do I need to take that day of rest and how important is it?


Is there a connection between Depo-Provera and hair loss?

I have taken three Depo-Provera shots. My hair started falling out excessively several months ago. In looking for answers I found out that this is a side effect to the shots. I was not informed of that before I took the shots. I saw in one of your Go Ask Alice! answers that depo-provera suppresses the Follicle Stimulating Hormone and the Luteinizing Hormone. What is this hormone? Is this what makes my hair fall out? And do you know if there is anything I can do to stop it? My next shot is due by May 15 but I am not going to get it. Thanks.


What to do about bleeding nose and gums?

I just came here this fall. Since then, my nose has been bleeding occasionally without any injury. My friend told me it was because of the dry air of U.S. Is he right? How can I prevent this situation? I also have a problem when I brush my teeth. My gums are always bleeding and not just a little!! What should I do? Thanks.


Is body fat genetic?

I am a female, five feet tall and about 127 lbs. I am not satisfied with my size. I am not obsessed with weight but with the way I look. I am very strong and have plenty of muscle. It just happens to be covered by a thick layer of fat. Yes, it runs in my family. On my father's side everyone has trouble with their weight.

I am writing to you because I don't understand why I am not losing weight. I am a vegan. I have no dairy products and no fat content in my diet. Except for the occasional pat of margarine and fried falafel, I don't see why I haven't lost weight because I just cut the dairy products out about two months ago. I have been a vegetarian for 9 years. I ride a stationary bike twice a week in my target heart rate zone. I work out with weights and do calisthenics in my room every night. What is wrong? Is there another factor I am not considering? Glands? Do I just need to be patient? I like being big, I just don't want it all to be fat.

Thank You.
