I am a woman who has a family, full-time job, and a very busy life, generally.

Three years ago, I joined a local health club because I was not getting enough exercise. Since then, I have tried to work out three times a week. Every time I exercise on the treadmill, even though I am not running but only walking fast, I experience leg pain in the back of my calves. I have tried stretching to warm up but nothing seems to help. Do you have any suggestions? The pain in my calves is preventing me from increasing my speed and improving my conditioning. I would appreciate any suggestions you might have.

Most of my friends and I often eat out for many of our meals. What are the effects of this trend on health?

Can I run when I am pregnant?

I've been taking a daily supplement of 400 IUs of vitamin E. I recently bought a bottle of 1000 IUs, and a friend told me that that's too much to take, and could even be bad for me. Is that true?

First of all I would like to thank you for your work and help. Could you tell me, what is the significance of expensive food sensitivity tests based on IgG values? Most people receive a list of dozens of foods to eliminate from their diets without causing them any problems. I think it can lead to develop eating disorders or nutrient deficiencies. What do you think? Thank you so much for your opinion!

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!

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?
