Do you mind if I ask you a few questions?
Do you know why you are going off plan in the middle of the day? Is it that the foods you have planned not convenient enough, or seem like a chore to make? Have you been eating the same thing for a while, and am now tried of it? Or are the things you plan just kinda bland tasting and you find yourself just not wanting it?
For me, when I find myself wanting to stray (or actually straying
) I try to figure out why I'm doing it. For example, I find that if I don't change my lunches around, I stop wanting them, and if I don't want to eat something I start resenting it whether I eat it or not. Or even if I like what I'm eating, if I let myself get too rushed, I feel like I don't have time to make something at all much less something that I will enjoy, so find myself scrambling for something to eat.
