I recently have run into a few problems that have completely killed my appetite. As of today I have lost about 8 pounds in a week. My meals have been whatever I can choke down when I feel good enough to eat, but my activities are still fairly high, including my work day and lighter training sessions 4 days a week for about 2 hours a night. My question is does anyone know some of the common and hidden physical problems with this. Basically I physically feel alright, just weak and tired.
