Is wheat bread out? I can do rice. My previous carb ups have also consisted of low fat granola bars, yogurt, a little fruit, fig newtons, pretzels and my meals are basically vegetarian (ie. baked sweet potato and a salad - low fat dressing).
I noticed Starbuck's frappacino's are low fat. I could happily carb up on those all day but might find myself levitating from all the caffeine.
