Is this the first time you've ever been on a regimented diet? I ask because it's usually the case that beyond the biochemistry of diet and nutrition, our bodies tend to react different ways depending on the person in question to certain inputs. Some people think C+F meals are a huge problem, others don't. Personally, the only reason I think they're often a problem is because they don't include enough protein; that said, oatmeal+PB is a great C+F meal that's a staple for many.
So, give it a shot. See how your body reacts. Personally, I don't like eating a lot of carbs when I'm lifting, but when I'm just running my body really sends me signals that it wants/needs lots of carbs. Listen to your body and don't be afraid to try things out.
