Low blood sugar can also cause exercise-related blues. The body's blood glucose level typically drops sharply about 20 minutes into a workout.
To minimize the resulting unpleasantness,have a light snack within half an hour of starting the workout, and another right afterward, preferably some combination of protein and carbohydrate. Those "fitness bars" like MetRx are made for this purpose but aren't necessary.
And remember to drink plenty of water before and after your workout-considerably more than it takes to quench your thirst. Even mild dehydration can slow mental processes, compounding feelings of depression.
I'm too lazy to footnote these points, but they've been well-researched and are generally accepted in the fields of athletic training and sports medicine, as you'll find by browsing the fitness magazines at any newsstand.
