It can. One thing I try to think of is "get your vanity in check". A lot of people get quite vain after their weight loss. Of course, there is a certain sense of pride in appearance after and that is natural, but some people tend to go from one extreme to another and leave their senses in the dust. Just as this journey means thinking each day "I should stay on plan" it can also be just as important to think 'be humbe'.
I am back to maintaining, I was 150lbs in November (and 170lbs from the baby) and now back to 127lbs. I find myself looking in the mirror a lot, obsessing over clothes, being just plain vain in general (you think after 10 years of maintaining I should know better by now), I do consiously think "BE YOURSELF".
