I'm sort of in a phase right now where I'm getting back into going to the gym on a daily basis, and have mainly been focusing on light cardio.

I plan to start lifting again next week. This will be different than in the past, however, because as of late I've been getting up and going to the gym before work. I might have a bit of coffee on the way, but I generally don't eat at this hour (about 5:30).

Anyone of the opinion that lifting basically right after waking up, without eating anything, will affect my progress? Is it important that I eat immediately afterward? My old routine had me working out immediately after work (a few hours after lunch), and consuming a protein shake or similar after my workout. I really dislike going to the gym after work, but I don't want to prevent progress, either.
