For the average cyclist, have you found that eating habits, more importantly, the types of foods/drink, have a result on training efforts and gains? If so, are there any foods/beverages that are known or thought to have a bigger negative affect than others? And NO, I'm not looking for "yeah, eating a large pizza and a 6 pack a day isn't good" answers. When I used to run (limited) I really felt that cutting out carbonated drinks helped my efforts. I'm not sure why but I could tell a difference in how I felt and how well I performed, depending on "coke" consumption.
