Don't improvise during the day. Plan what yu will eat for breakfast, and at lunch. Make sure the lunch is a big meal because of the scheduling. Bring food from home so you will know exactly what your are eating, and exactly how much. Eat enough for lunch that yu aren't hungry at 3. If you must have a sanck at 3, make it an apple or other fruit, that will make you feel satisfied without many calories.
