They are your points, so you can do whatever you feel comfortable with.
For me, during the work week I have a big breakfast and a big dinner and a small lunch. Then I have a snack later after dinner. Because of my work schedule I eat dinner at about 4:30, so this is what works for me.
The weekends are totally unpredictible (and I'm off Fri, Sat, and Sun), but I'm usually eating out to dinner at least once or twice on the weekends, so I plan for a small breakfast, small lunch, and then save the bulk of my points for dinner. If I know I'm not going out to eat, I might balance the points a bit more equally among my meals. I also use AP or weeklies on the weekends, too.
It's just a matter of finding what works best for you
