Sounds like he's aiming to recomp. Correct me if I'm wrong. Are you trying to stay in the 160lb range? Find a BMR calc, maybe even a couple, plug in the necessary data, average the maintenance cals from each one and try to abide. Your best bet is to enlist in an online calorie calculator/food log until you can get a confident feel for what calorie totals you'll get from your everyday meals.

It's very useful once you've made an account, and can also get a full overview of your macros once you've entered meal data.
One note to keep in mind, is to think of carbs as a fluctuating variable while leaving your other macros at their respective ratios. If you gain too much weight, drop carbs gradually from the meals AFTER your post workout meal, replace these carbs with fibrous veggies, and suck down the water to feel satiated.
Weigh yourself weekly, under controlled conditions (if you weigh fasted in the morning, weigh yourself fasted in the morning the following week). Keep your methods consistent until you stagnate, lose, or gain too much weight and adjust cals accordingly.
