For me, when I decided to go off plan I didn't consider it cheating because it was my choice. Now if I went in a corner and ate a whole cake I would say yeah I cheated.
I stayed 100% on plan until June 17th weekend. So we are talking 16 weeks I stayed 100% compliant. On that weekend I decide before hand I would have 3 healthy square meals. No chips, fruits or deserts. I stuck to it. I did have bread on a grilled chicken sandwich at a restaurant but I skipped the fries. I went off plan but it does not mean I can go all out and eat anything I can get my hands on. I am trying to re-teach myself self control when it comes to food. When I go on maintence which is not too far away I want to be confident that I can say no to the junk food that still is in my house for the rest of my family.
So try not to think of going off plan as cheating. That makes it sound like you blew the whole diet and you might as well eat anything in site and out of site because you will "start over" tomorrow.
I think because on my off plan days I don't pig out I have been able to get right back on the MF plan with no problems. No hunger, no headaches and still feel great.
Good Luck.
