I have heard that if you exercise/work out in the morning before you eat breakfast that it will cause your metabolism to increase throughout the day, helping you to burn calories. Is this true?

I just got a diet tea that contains senna. How is this herb bad for your health? Is it unsafe to drink it everyday to lose weight?

Thank you very much.

I am a student who is a very picky and health-conscious eater and have grown tired of the food offered in the cafeteria. A good portion of my dietary consumption is in the form of natural peanut butter. I can sit and consume half of a jar in one sitting because I get so hungry and it is the only thing that really satisfies my hunger. Is this a bad thing, and if it is, how can I go about fixing it?

I swim three times a week for 40 minutes and sauna for 15. When I come out of the sauna my face is beet red and stays that way for about 1/2 hour — is this a sign of something wrong? Also, is it bad to work-out (sit-ups, push-ups) in the sauna?

I am a 29 year old woman. I am interested in increasing my muscle mass. Could you please tell me what steps to take in weight lifting as well as in changing my eating habits for a healthier diet?

I have a problem with food. I hate it and never know what I want to eat. Sometimes I'll be famished to the point of shaking, and I'll just lie there thinking about what to put into my body, sometimes for hours. I know I should eat something, and I really am hungry, but at the same time, nothing appeals to me. Is this a form of anorexia? Or could it be a symptom of stress, depression, etc.? I would really appreciate it if you could help me.
