In the spirit of trying to help you, let me ask you this... will the wedding stop if you don't get under 200? I am guessing that the answer is no and it should be No. But since the answer is most likely , a no, I am thinking that this is not a serious goal for you. I find that most people who attach a goal to a wedding, or getting into that dress or attending a event, don't go on to achieve the weight loss goal because we know in our minds that the day will come whether we are ready for it or not and we will attend it anyways.
Weight loss goal should be for a more important reason such as health, well being and because you are doing it for yourself. Then it will be important enough that you will actually do it.
But having said that, it happens often enough and to many people that weekdays are good on track and come weekend, the whole thing goes by the way side. While it is perfectly ok to indulge a little on special days such as your bridal shower/party, if you are really serious about losing weight, just be mindful of what you eat on the weekends, no need to be extra strict with yourself but do some portion control. And if all else fails, wear proper fitting pants and that should help you to atleast not overeat
Best Wishes for your upcoming wedding and Good Luck for achieving your goals.
