I have to concur with everybody. I have a sloppy metabolism and some sensitivity to low blood sugar. I have to eat breakfast or I am bonked from the get-go in the morning. I have always been able to eat a lot without it showing much and if it does I can take it off pretty easily -- really I have to eat a lot or I don't function well mentally or physically.
In non-touring life, regular meals are low meat, lots of vegetables, whole grains including homemade breads with fresh ground grain. Standard what-is-now-considered-healthy diet. I didn't train myself to eat this eat this way because it was supposed to be healthy for me. I did it because I realized I felt better when I did. You get the picture. But when I go on tour....
Breaskfast - Camp breakfast is never enough. I can't function. (In general camp meals never are enough no matter whether it's breakfast, lunch or dinner.) Camp breakfast has to be followed by more. Typical breaskfast - eggs, bacon/sausage, toast, hash browns/pancakes, juice.
Lunch - Hamburger or similar, french fries
Dinner - pasta, pasta, pasta, and salad.
Snacks - often one in the morning. Certainly one in the afternoon. Gatorade or something similar in there for fluid and electrolytes.
In general -- LOTS of fats, carbs and a fair amount of protein.
I would never eat like this at home. I'd consider it a heart attack waiting to happen. But I have found it is what works for me touring. My body is telling me this is what it needs to be able to tour day after day.
