You should (must?) be honest in your profile, but there is such a thing as being TOO honest. If you are truly just a few pounds overweight, just select “athletic build” or “average” and leave it at that. You do not need to address your weight (ie. I just gained 10 lbs because I had a broken foot, I’m usually much thinner), let your photos speak for themselves. If you are a Democrat, you don’t need to discuss in your profile why you would never in a million years date someone who voted for Romney. It may be true, but it’s TMI. If you are 3 credits short of a Master’s degree but haven’t finished yet because of work/health/etc then you make the decision of whether to put BA or MA for what level of education you have, but no one needs to hear the details. Frankly, until someone gets to know you, they don’t care. All that detail does is make someone think that you are high maintenance, dramatic, and just too much to deal with.
