I just got into cycling by commuting. I bought a road bike, a cheap one, but nevertheless, I ride the hell out of it. I've got a 15 mile round trip commute that I do 5 days a week + errands which adds another 1 - 5 miles a day. On top of that, I like to get in 30-50 miles on Saturday. I try to take it easy on Sundays, but I get bored and ride at least a few miles.
I'm fairly sure that I'm overtraining, because it feels like I'm starting to slow down. I've dropped about 15 lbs in the past month. I've got about 15 to 20 more to go. I put on a good 30 lbs in the past two years from eating fast food once I started college . . .
I've read that protein supplements can help with overtraining. Would it hinder my weight loss though? What are some good brands/types to start with? I'm totally new at this.
