I lost nearly 20 lbs last year, and it was definitely due to less eating in part; I went from a size 8/10 to a 4/6. However, if I were to also sit and think about it, my lifestyle has significantly changed due to my current boyfriend. He doesn't drink. We ended the phase where we went out to eat all the time, and have spent since last summer most of our Monday and Friday nights at the gym. While I've always exercised 4+ times weekly, when I am in a romantic relatioship, usually restaurants play a bigger role in my life. I spent from 2000 to 2003 wondering why I couldn't lose weight when I was always at the gym! It's hard to control calories and alcohol when out on the town by the way. I didn't realize, but I spent a good deal of my 20's (honestly, most) drinking and having fun with friends. In fact, when I tried to curb my drinking it was hard because all of our social interactions involved booze. So while I've in no way become a hermit at 30, I have really cut down on alcohol, mostly because it's just not around anymore, and again, someone significant in my life doesn't really care for it. I have no idea about your social life, but it seems like I wasn't even aware how much drinking I was doing, I used to drink all the time at home, even by myself, but those calories really add up. Basically, from my own 2 cents, you may want to cut alcohol out for awhile and see how that works out for you. Good luck!
