Your last meal (or two, if you're eating more frequently) of the day should emphasize protein rather than typical slow-burning carbs like pasta. The carbs you do ingest should be the "wet" kind contained in high-water, medium-fiber foods such as cucumbers, leafy green salads, tomatoes and steamed asparagus. High-fiber, low-water foods leaching water out of your system; wet carbs, on the other hand, allow you to maintain relatively adequate levels of water during the night since you can't drink while you sleep.

Here's a bonus tip: Get in the habit of eating fish as part of your last meal of the day. Fish makes for a lighter meal, and it's a good way to replenish aminos while getting essential fatty acids. Fish is healthy as well: The American Heart Association recommends at least two servings of fatty fish (such as salmon and tuna) per week.
