Well, I'm sick as a dog.  I just try to look at the bright side, though.  I mean, I get a headache, feel nauseous, stuffed nose that somehow manages to leak, perpetual thirst from mouth-breathing.  There has to be something good, right?  Seems like everytime I get sick, my body fat drops.  Last time I got sick, I made sure to keep eating, because I KNOW I need the calories, and when I got to Sunday (weigh in) my body fat had dropped almost a full percent.  That's almost 2 pounds of body fat.  Of course, I use a BEI (Bio-Electrical-Impedance) equipped scale, so it's surely just an estimation, but I use the same scale each week, under as similar conditions as I can control, so it is still relevent.  I swear, little viruses must be the best cheap fat burners around, because they always seem to do that trick.  Of course, if it were my choice, I'd stick with the half-pound a week I can lose at the gym and the dinner table.
