I do almost all my workouts before work. BUT I usually eat something beforehand, which helps.

This morning, I was up at 5:15, ate two pieces of toast with honey, drove to the pool and was in the water at 5:50. My swims are long enough now (~1:15) that if I don't eat before I leave the house, I'm really hungry before I finish the workout! A piece of toast or two (or sometimes an apple or a banana) gets me through the workout in good shape.

I tend to struggle with hunger during the day too. I try to eat more in the mornings, including more protein, but usually by the end of the day, I'm pretty damn hungry again. I make alot of poor choices between 4pm & 6pm, which I'm sure is why I'm having trouble taking off the 10 pounds I've managed to put back on. I should probably be eating a substantial snack around 4pm so that I don't make bad dinner choices, but it's hard enough to find the time to make and pack my LUNCH, much less figure out my dinner options too. Some weeks I'm really organized on Sundays and i spend a few hours cutting and chopping veggies and the like so that I can make quick healthful meals as soon as I get home during the week, but other weeks all my good intentions fall flat.
