I am in the process of doing this on purpose.
Over the holidays I took a break from exercise and calorie counting, within reason. I had been on a plateau since the beginning of October at 158. My mini hiatus broke my plateau after a slight gain. It's been amazing! My workouts are better, my energy is doubled and my enthusiasm for my plan is increased. It IS like starting over again, only better.
I highly recommend taking routine PLANNED breaks within reason. I'm going to start doing this routinely every 12 weeks. A break for me means no exercise for 1-2 weeks. I tried 2 weeks but just couldn't stand it any longer so I ended up back at the gym after just over a week. I think a week is probably plenty of time, but I hadn't had a break in year. For calories I am starting to cycle higher calorie days with lower calorie days. There is a very precise schedule for calorie cycling, but I am doing it intuitively. Most of my days tend to be low calorie based on how I feel, but then there are days I am just ravenous, so I'm giving in to that.
Good luck, and congratulations with getting right back on plan! That's the only problem with what I'm doing right now. Sometimes people find it's too hard to get back on. It's easier to stay the course.
