Lately, it seems that I'm eating all day.

breakfast (8am) - usually toast with peanut butter or yogurt with granola.
snack (10am) - banana or grapes
lunch (noon) - whatever looks good in the cafeteria
afternoon snack (2pm) - fig newtons or chocolate or pretzel sticks
late afternoon snack (5-6pm) - pretzels or cheese
dinner (7pm) - depends on the day...

While I'm not losing weight, I'm also not gaining any, so I guess this is working...
