Sometimes I eat nothing, but I try to consume 60-90g of carbs every hour or so in liquid form while on the bike (usually a 2:1 maltodextrin//fructose homemade mix with grapefruit flavoring). If I do eat, unless its something simple like a bowl of rice with soy or other non spicy flavoring, it has to be at least an hour before. Try to take in caffeine in some form prior as it does help with perceived effort; there is a liquid product that I can have in water (much less acidic than coffee, but I do like my espresso). Can also add that to the carb bottle to keep topped up.
After, a protein shake, usually.
