My fiancee bugged me to write this. It appears she's too lazy to type for herself... *gush*
According to her, she usually doesn't waste time counting calories (she sucks at math, anyway. even with a calculator...but she's an art whiz!) and watching too much of her weight, and even I think if you try too hard you'll never see results.
Actually it's pretty embarressing to say, but she bought a game called Dance Dance Revolution and plays it on her ps2. Then she dances at home and enjoys it immensely.
What I think she's trying to put forward is not to be too conscious about losing weight. Instead, do anything you enjoy like dancing, tennis, playing at the arcase (those hockey games where you use those hand thingies to hit the puck into the opp. player's goalie.) 3 times a week (maybe one or two games...or just take long walks, take some time to go cycling at the beach (she does that with me every week since she's been doing it since young anyway).
She did once became a caolrie counting monster but she neded up piling more weight and not losing what she wanted to lose.
In fact, don't even think about it. Just enjoy yourself, don't step on the weighing machine more than once a week, go play, party, walk, spend more quality (NO TV!) time with your loved ones...
believe me if you just did that that entire tub of cookie dough ice cream you just spooned down wouldn't make you feel as guilty as if you felt like you "failed" in stopping yourself with calorie counting craze.
Btw, eating porridge, soupy noodles, drinking lots more and being more conscious of "how" you eat (etiquette) than "what" you eat actually burns more calories. 
Don't be put down by those mass-manufactured chinese size -10 chinese girls walking around with their flat chests and rebonded hair (said partially to make us all feel better about not being anorexic *grin*)....
