Dude-

Get thee to a registered dietician!!! McDonalds is a heart attack in a cardboard box, and half of the rest of your diet is eaither loaded with saturated fat or too much salt or both. Eating off a buffet is a big no-no unless your plan is to resemble Jabba the Hut. You need to completely re-evaluate what you are eating and exercise portion control. As for pre-ride, you need to eat SOMETHING. Skipping food before you ride is like driving your car with the gas gauge on E. You will eventually bonk. Grab a banana or a granola bar. You will still be hungry when you get to the restaurant. A multivitamin would be good too, especially since you don't like your veggies. And water, lots and lots of water.
