Welcome!
I don't know what it is about marriage, but i've gained about 20 lbs since getting married in October. My husband and I lead very different physical lifestyles so me eating the same food and portions as him *shame* has bought me to where I am today. And I blame the birth control too, cuz the blame can't ALL be on me now, can it?
I think it's very possible to lose that weight, but because you are lighter, 10lbs is a higher % of your total body weight than for others, so you'll have to work at it. I may be having issues with my scale but I have dropped a few lbs in this week alone. All the best with losing those pounds! Do you have an idea yet what you want to do? I am trying the south beach diet and have just started the 30 day shred videos by jillian michaels. I don't know yet what the results will be like, but the diet has been very reasonable so far, and the video was killer!
All the best!
