I've had days like that but I'm getting better a out them now. I could see myself getting obsessed over numbers and calories as that's not good. If it really bothers you then maybe workout a little bit but I think the important thing here is to train your mind. We all need to indulge at times, it gives our mind and bodies a rest from the stress of dieting. Everyday Is a new day and one day of indulgence is not going to hurt your progress! Go for a nice walk somewhere, remind yourself of your goals and how far you've already come! Don't be hard on yourself

Depending on my level of participation, I will either log my binge and shame myself into improvement, or I'll just say "I'll start again tomorrow." and shame eat a whole pizza. This tends to go on for several days in a row...Sometimes weeks.
