Sailorboy Slims Down

What’s a good idea for a late night snack?  I usually have dinner around 7-8 and then by 11 or so I’m hungry.  I know this is a part of the plan, but this is probably my worst control time.  I just want to eat.  I’ve been having a protein/water shake the last couple of nights, which has helped.  I’m sure it’s better than half a bag of chips/salsa.  haha.  But what should I be eating?  A lot of carbs/not a lot?  A lot of fat/not a lot?  Protein?  I’m not really educated on what you should be eating when.  A lot of the meal plans I see have a protein shake as your last meal.  Isn’t this a bad time for protein?  Any takers?
