I don't plan my meals in advance. I generally have the same few options for breakfast, decide what I'm in the mood for for lunch, and I'm always in a hurry around dinner time (that's what time I go to work and class) so I usually eat a packaged light dinner.

thanks for the replies & the Starbucks reccomendations.. The one I get is loaded with whip cream, chocolate, etc... LOL!! Yum!!

I am a planner - the day is planned always a day in advance, dinners are usually at least a few days in advance. Sometimes I even plan a week in advance. I do leave some room open for one or two Triple Tall Non Fat Lattes (I work at SBUX and these are not something I want to give up!!). What I "earn" with my exercise I also allow myself to use in case of emergency, so those things are not planned.

It would drive me bonkers to have to plan everything that goes into my mouth beforehand; I would hate to give up the option of eating what I feel like, in the moment. I just choose what I want to eat, weigh it, eat it, and then add it to my spreadsheet afterwards. It helps that I am almost always home for meals and snacks (I work from home during the school year; in the summer I am at home with my kids) and so I pretty much only have healthy things to choose from in the house, or just choose to stay away from the high calorie stuff.

I try to make a big batch of something on Sunday that can be divided into lunch for the week. Dinner I play by ear. Of course, I often forget to bring my lunch, and then I buy something and have lunch for dinner when I get home. That makes less financial sense, since if I bring lunch I will also usually cook dinner, but it often feels better to me to have a big lunch and small dinner, since I tend to have dinner late and lunch has to fuel me most of the day.
