What happens if there’s a day where I can’t cook, or I’m going out with friends?

That’s no problem – just swap meals around in your planner and update your grocery list. Take the concepts of healthy eating I give you in the plan to try to make fairly healthy choices, and then pick back up the next day or the next meal. If you didn’t know in advance, and have already gone grocery shopping for the week, you can make the meal you missed as an extra meal another time.
