I am currently working on losing a couple of kilos ( ie about 5 pounds) using the same method I used to lose about 10kg last year. It's very, very slow ( i was recovering from surgery, so took it pretty easy at first) but it worked for me. I'm 46, 5 7, and now weigh 65kg or approx 140. I'm ever so slightly inbetween sizes right now, hence the desire to lose a litle more to fit smaller pants well, instead of swimming in larger sizes.
Anyway, I use MyFitnessPal to keep a food diary, and walk my dog for 40 mins a day, everyday. I take public transport to work, and do a bit of incidental walking to & from the station, and around my workplace campus during the day. I do an extra 30-60 minutes of yoga or swimming everyday, too ( we have a pool at work). I did yoga at home in front of DVDs or downloads for the first year, and have been going to Jivamukti classes twice a week since January. The classes are social time for me, plus I enjoy the sense of community, and the meditation/spiritual practice aspect.
In terms of eating, I was ( and am) mostly vegan. My downfall in terms of weight gain was portion size, and 'empty' carbs, including, yes, wine. Raising my protein & green veggie intake & dropping alcohol to an occasional treat helped a lot. On reflection, I think I sleep better when I'm not drinking, too.
We have lots of Biggest Loser style personal trainers here who insist you can't lose weight from walking etc, but it does work for me... The weight comes off very very slowly though, at about a kilo (or 2 pounds) a month. My body shape has changed pretty radically in terms of measurements and muscle definition, and I haven't gotten 'saggy' ( a real concern at my age, ahem).
I felt like I already ate pretty well, but overdid the wine & snacky food as a response to stress at work, so chose a 'stress management/habit shifting' approach, rather than boot camp, but ymmv. Given the situation you're in though, whatever you do should probably contribute to overall well being, not add extra aggravation in your life.
