I'm curious to know if going to the gym increases sexual drive? I am a female in my 20s and recently started an exercise routine (running and weights), and I have noticed that my sexual drive has increased significantly. There have been no other major changes in my life, and I have been dating the same man for close to two years now, so I can think of no other real reason why my libido would have increased. Is there any real connection between working out in the gym and beneath the sheets?

1) Is it true that eating fat keeps the body warm in cold weather?

2) What I'd like to know is, does my body burn more calories to keep me warm when it's cold out? Thanks!

Once a day, after meals — whenever my roommate isn't around, I stick my fingers down my throat and throw up most of the food that I had just eaten. I do not binge — I only purge. I understand from my Psychology professor that the diagnosis of bulimia nervosa requires that the person binge and then purge. I am curious, then, what I have — do I have a form of anorexia nervosa or what? Also, I am on birth control pills and I am afraid that I might hurt their effect by throwing up. How long does it take for the pill to get absorbed into my system? I usually don't throw up until about 5 or six hours after I have taken the pill. Will this hurt the effect of the pill?

1) Do you recommend any natural remedies (Melatonin, etc.) as dietary supplements for healthy living?

2) I have been seeing a lot of ads on dietary supplements and have been thinking about trying them. However, I'm not sure if it's a good idea. Could you please tell me if the use of dietary supplements is really worth it?
