Always eat breakfast to jumpstart your metabolism and drink 24 oz of water first thing in the morning if you can too.  Water makes you fuller faster too, so if you have this first thing, you will mindlessly snack less.  (or in theory you should unless you're eating from boredom)

You'd be amazed that if you focus on getting your water in first thing, it's much easier to get your necessary quantity in before the end of the day.  Plus, you aren't drinking right up till bedtime and then peeing all night.  Water is my biggest struggle.
