To answer for myself personally, I don't eat it every meal. I tend to eat it for lunch on the weekends, if I don't have any particular lunch plans. It's cheap, reasonable-calorie and doesn't make me feel lethargic after eating it. In fact I feel pretty good after drinking one, usually. The only reason I don't drink them more often is that it leaves me just slightly unsatisfied, and that dissatisfaction is distracting when i'm trying to concentrate on work.
