I find that I am constantly hungry. I am spending much more of my time training and less time planning my meals. I double the quantity of oats before my long runs or events. At work during the day I usually have a BIG fruit salad with at least 5 different fruits and a plain soy yogurt. Sometimes I sprinkle on some muslix on top of the fruit.
Lunches are usually salads, baked potatoes, or dinner left overs.
Notice, the fruits are usually in the a.m. so the tummy is ready to run without pit stops in the p.m. If you don't have to run in the p.m. another good snack is tofu with salsa on top with tortilla chips or crackers. Also, I eat papaya enzymes like candy after meals. I usually have steamed veggies, rice, and seitan or tofu. Other than that, my diet is pretty much what it was before minus all of the animal products plus the addition of tofu, tvp, seitan, soy milk, soy yogurt, etc.
