I aim for every 2 to 2.5 hours getting in a meal. Every meal should include protein. A favorite of mine is a grilled chicken breast with one half avocado chopped, with a roasted red pepper on top. That would be a low carb meal. Earlier in the day would include more carbs ie half cup brown rice, with maybe a lean turkey burger patty. look into a whey protein for post work out and if you really want to go all out a casein protein for bed time, it will release slowly through out the night. Losing weight is 70% what you put in your mouth the extra icing on the cake is working out.
