I hope I'm about to answer your question correctly.. If you're on the main page and you click on Track My Food, it'll take you to the tracker. Then around the middle of the page, slightly to the left you'll see the date (just to the left of the water tracker). Underneath the date is a little drop down that says "Tracker Options." This will allow to to turn on/off meal plans to switch between planning your own meals or letting SP plan your meals for you.
