I think it depends on the person.
In the past couple of weeks, I aborted my food plan. Not badly but I was not on it like I would have liked to have been. I have been moving and I am now moved. However, the time frame of when we were supposed to be out of our "old" apartment was moved up by 10 days. Yikes! It was just my DH and I so every night after work, we would take some of our stuff over to our "new" apartment. Now, I am obese, arthritic and not as in shape as I would like to be. I felt really guilty that my DH seemed to be carrying the burden of some of this.
However, while he walked up and down endless times on the same steep stairs I did put away the stuff. I usually can not stand longer than 45 minutes before my knees and hips hurt. Last Saturday, I did a record 9 hours on my feet. Needless to say, I couldn't walk afterwards either. It took taking the maximum of my pain relieve medicine for 36 hours and lots of Icy Hot to get me back to feeling "normal".
I know this is a long about way of saying that yes that voice does occur. I figured I had to be burning off a lot of the extra calories I was consuming. I mean, I was soaking wet with sweat by the end of the night. That was my "excuse". And, yes, it is an excuse. At least, I am wise enough now to recognize it for what it is.
I listen here about people traveling and still staying on their food plans and quite frankly I feel like they are saints and I am a

sinner but the reality of it is. I am what I am. I am a recovering compulsive overeater.
You lose a couple of pounds and still reward yourself with extra food. I move a couple of boxes 10 feet and have homemade fudge because I "need my energy". Six of one and half a dozen of other. It is still an "excuse" for going off yours (and mine!) food plan.
The turning point is when after you fall off the wagon you dust your butt off and jump right back on. I did that this past Monday and I am now working off those "water weight"(you think?) extra couple of pounds. I now know that I won't make my Mother's Day goal of losing 50 lbs. I am disappointed by that but maybe Memorial Day??
I guess, one day you have to decide how bad do you want this. I want it bad enough where I will forgive myself for the detour. I wish I handled "sudden upsets" better but I did the best I could. I did keep track of everything on my food diary and I stepped on the scales every morning. I wanted to face the reality of what I was doing no matter how it made me feel.
Now, after having drank lots of water and corraling my sweet tooth (and pizza tooth) I am losing the 4 lbs that I gained.
I'll do better next time. I hope you will too.
