It depends on a lot of things. Are you currently tying to gain weight (muscle) or lose weight (fat)?
What is that last meal look like typically?
Personally, I eat 5-6 times per day, whether I'm trying to gain or lose (gaining or losing, I just adjust food amounts accordingly). No matter what, the last 2 meals of my day are low-to-no carb. My second to last meal is typically a protein shake (because I'm at work and it's easiest) and my last meal of the day is some sort of lean meat and a large salad or lots of veggies. This works for me because all of my training (MA, weights, conditioning) is during the day, about mid morning. So the 2 meals following my workouts have carbs in them for glycogen replenishment. But the last 2 meals of the day have no carbs, but lots of protein.
