Is it okay to eat past eight?

I am trying to lose weight this summer and I am doing great with my diet and exercise, but some days I am eating too few calories, and tonight I snacked on a few things like popcorn, blueberries, trail mix (healthy kind..no candy, just nuts, banana chips, dates, and walnuts.) and a weight watchers cookie. I was watching a movie and ate this all after 8:00...is that okay?
