Exercise - in the cold months I hardly do any at all. I have taken up karate again and I go 1 or 2 times per week (DD has archery practice that conflicts with karate sometimes) and that workout is for a fairly intense hour.
When it's warm enough I take the dog for walks - but just walking at a good, not fast, pace. At the moment I would say we get in 2 good walks like this per week - usually 45 minutes or so. The days are getting warmer here so that will probably increase closer to our trip.
That's really about it. I don't belong to a gym ($$). We do have some free weights at home but I never use them.
Food - I don't have a kitchen scale for portioning. I like the salad idea - usually eat more salads in the summer than the winter (better produce, cooler meal) but I can add that back in now instead of later.
I'll be honest by saying I would do better - especially for lunch - with premade meals (like lean cuisine stuff) because it gives specific proportions, is easy to fix and has veggies. I tend to reach for chips if left to my own.
Well, I'm not a personal trainer, nutritionist, doctor, etc. I have absolutely no training/education in these fields, so take what I say with a grain of salt, but...
About two years ago I started losing weight, I think it was mid-April 2009 (I didn't really mark the day on a calendar or anything). I started at 193.5 and size 16 clothes were pretty tight on me. By January 2010 I was at my goal of 120 and size 2 clothes were a little baggy on me. About a year later, I've mostly kept it off, I tend to hover between 123-127 and am still wearing size 2. I did it without a personal trainer, without weight watchers/Jenny Craig, etc., without a gym membership, without advice from a nutritionist...
What I did:
1. Measured and recorded EVERYTHING I ate. If you are serious about losing weight, think it's important for you to buy a kitchen scale. It's really important to really know how much you are eating. I know I was really shocked that what I thought was a reasonable amount of any given food, was actually considered 3 or more "portions"! I recorded everything I ate in on sparkpeople.com, but there are other sites out there where you can record your food.
2. Focused on eating mostly whole, unprocessed foods. I read something somewhere about "eating a rainbow every day" and that has really helped me ensure I am getting in plenty of fruits and vegetables. Greek Yogurt is a huge part of my diet. I buy Fage plain 0% (non fat) at Costco. If the taste is too much for you at first, try adding a little bit of honey or maple syrup, you can gradually decrease it (if you want) as you get used to it. Now, I love it plain, I think it's delicious! We also use it as a substitute for sour cream in recipes.
I LOVE my George Foreman grill! Makes it so easy to grill up a chicken breast to eat plain, or add to salads or whatever.
3. Excercize.
Since I started in the spring, I was able to get outside for excercize a lot. I would go for hikes in the woods, walks around the neighborhood, whatever I could! I also started some workout dvds with weights. The trainer's name is Jari Love and she has a series called "Get Ripped" and another called "Get Extremely Ripped". I love them, especially the original "Get ripped" series! I noticed you mentioned that you have a few weights, I know that some Jari Love DVDs are available on Netflix, or maybe your local library has them?
After I lost most of the weight, I started running. I read online about the "couch to 5k" program and tried that, kind of modified to my own needs. Before I knew it, I was running 3 miles, 3 days a week! A few months later I increased it to 5 miles...and then gradually increased it to 7 miles one day per week, 5 miles the other two...then 10 miles one day per week, 7 miles the other two...and then it got cold and I've been lucky to get in 1 run a week
But I have NEVER been a runner before. Seriously, back in school, when they'd have those physical fitness tests once per year and you'd have to run around the track, I was the girl that walked the entire time! I NEVER voluntarily ran! This is huge for me!
Anyway, since I'm not getting in as much running as I'd like, I'm supplementing with different cardio DVDS (I have a Tae bo one that I like) and I'm always checking out the On Demand Excercize Tv section to see if anything looks good. Lately I've been doing a few by Kendall Hogan. The ones on Excercize TV are about 30 minutes each, so I'll do two on my cardio days.
*eta Oh, I also have an elliptical in my basement that I'll use a few days a week when I can't run.
4. I rewarded myself. Each time I lost 10 pounds (about once per month), I let myself have either a Chick Fil A milkshake or a piece of Adam's Peanut Butter Fudge Ripple Cheesecake from Cheesecake Factory (Yum!). It was great incentive for me.
It was hard, but very worth it. After I lost the weight, I had some old clothing that was way to big for me. One item was a size XL winter coat, and I decided to sell it on Craigslist. When I met with the woman buying my coat, she looked at me and said "So, how does someone like you come to have a size XL coat?!?!?!"

That was one of the best things anyone has ever said to me!
Good Luck OP, and anyone else trying to lose weight!
