Summer, I'll answer your post separately, as I tend to go on and on about how I have lost the weight. You may regret ever asking after all this.
You asked what got me started and I really can't answer that, except that perhaps some kind of survival mechanism kicked in. All I can say is that I weighed myself in the middle of January 2004 and saw that I had gained 10kg since Sept 03. Now, at the time, I can't remember feeling anything in particular, or making any major decisions. But in the car later with my husband of 3 and a half years, I remember looking across at him and thinking "If you don't do something you won't be around to spend those MANY more years with this guy that you had planned." That seemed to be it for me. I had never had any bad medical results, but diabetes was in the family and I knew I was a time bomb just waiting to go off. I mentioned something to hubby, can't even remember what I said now, but it must have been about having to do something about my weight. Well, from that moment on we both decided to start some action.
The first thing we did was that we bought NO more rubbish food into the house. We didn't throw out everything we had, but once it was gone, there was no more. I was not good with temptation in those early days and knew that if it was around, I would keep thinking about it until I ate it. I didn't deprive myself of treats, they just had to be outside the home. So I would have something if we went shopping, or I would have a treat when there was a morning tea at school. Now, I don't even want cakes, candy or chocolate, and my treats are dried fruit, nuts and flavoured licorice. But early on I still craved things and probably ate too much at those times, but hey, it worked for me. We also started looking for healthier eating options, but only gradually, nothing too major to take in at once I don't think. Things like stopping drinking soft drinks and milk drinks. We have some nice fruit cordials over here that we have now instead. I also have diet flavoured soda water that I have to mix with plain soda water as it is too sweet for me now.
Halfway through 2004 I had a parent/teacher interview with a student's mum and found out she is a dietitian. Since then we have become very good friends and she has given me some fantastic advice to keep me on the straight and narrow.
Basically, what I eat now is mostly fresh fruit and vegetables. I try to eat as little processed food as possible. I start lunch and dinner with a large salad and then add a little something like boiled eggs on wholegrain crackers, grilled chicken, tuna, sushi (vegetable), low fat sausages, lean steak etc. I have three good-sized meals and 2 or 3 snacks. My dietitian friend likes me to have 3, but sometimes I give 2 a go to give my body a little variety. Snacks are mostly fresh fruit with yoghurt, sometimes nuts and often low-fat icecream. Oh, my salads have a basic base, then I vary what I add to them. It may be red peppers, snow peas, green beans, sugar snap peas, broccoli, cauliflower, chick peas, etc. Just things to add a little variety.
I've read up on Low GI eating and it seems to be mostly what I am sticking to anyway, but I do sometimes get a few ideas from there. I've never counted calories or points, or weighed food. Maybe I should, but so far things have worked with what I'm doing. Things are slowing a little as I get closer to target and as my hormones have kicked in again, but I think that is to be expected, so I just need to learn a little patience.
Oh... I didn't mention exercise. I KNOW I couldn't have come this far without combining the healthy eating with exercise. For the first year I just did my own thing. Hubby and I would go for long walks when we could and at other times I would 'exercise' to music in my lounge room. This involved a kind of aerobics routine, but I didn't really know what I was doing, I just made sure I moved. Early in 2005 I hired a treadmill to make sure I would get use out of it and then I bought one. For most of that year I used the treadmill first thing in the morning and again in the afternoon/evening. At the end of last year I got an exercise bike for Christmas and I now use that in the afternoon instead of the treadmill. I just felt I needed a little variety. I wasn't getting bored with the treadmill, and it is still my favourite, but I think my body wanted a change. I'm also considering the Walk Away the Pounds DVDs, as I have heard some great things about them.
I have definitely taken this on as a lifestyle change, so I don't break down at Christmas or holidays like that. I know that my 'system' is used to the way things are now, and doesn't need the other stuff. I did make a couple of special salads (such as sweet potato salad and caesar salad with low fat dressings) over Christmas and had a special low fat dessert for a few days, and they were treats enough for me. I didn't stop my exercise routine at all. I start my day with exercise and I exercise in front of the news in the afternoon/evening. It is just part of my day now and I feel lost if I miss a session.
You asked how I overcame the obstacles. Well, believe it or not, I didn't really have any major obstacles. You see, I have always told myself that it "isn't an option" so things seemed easier that way. When I looked at chocolate I just said "You can't have that Zelma". In fact, I'm sure I often said that out loud, just to make sure I was listening. I may have sounded insane to other shoppers, but at least I listened to myself.

When I came to a couple of little glitches, my hubby has been a rock of support and my dietitian friend has always managed to come to my rescue as well.
Well, I have probably blabbed on WAY more than you ever wanted to hear, but hopefully you have taken in what interested you and kinda just skimmed the rest.
If you have any more questions (if you are game enough to ask after this 'novel' of an answer) I am most happy to answer them. One of my aims is to help as many people as I can to make a healthier life for themselves. I am worse than a reformed smoker though and tend to want to tell EVERYONE how they can help themselves. I have to learn to wait to be asked. THEN they get an earful.
Take care and have a wonderful weekend,
Zelma
