If you think, “It’s okay to eat this unplanned food because I’ll eat less and make up for it later,” remind yourself, “Looking back, when has ‘making up for it later’ EVER helped me to lose weight and keep it off? I’ve already proven to myself that this idea just doesn’t work and that spontaneous food decisions have negative consequences. Just stick to my plan and as soon as this food is out of my sight, I’ll be SO GLAD I didn’t have any.”
