I started MF before Thanksgiving and the Christmas holidays ... I was not 100% compliant during the holidays themselves but I managed to maintain the weight I did loose before Thanksgiving and then again before Christmas--
but I did not loose weight when I was not compliant! I went off plan, but I remained disciplined--in other words, I did not binge and was sensible in my food choices and had
only one glass of wine with dinner on Thanksgiving and Christmas. This was a good choice for me because I began the new year already having lost weight rather than having even more weight to loose--I started with having over 100 lbs to loose.
I think you have to weigh all
your factors and do what is best for you. You have only 25 lbs to loose which shouldn't take too long
if you are compliant. Since your engagements are not that long off it may be best for you to begin MF when you are ready to fully commit to the program. But again, this has to be your choice.
Hope this helps. Good luck!
