I just want to point out something I thought was extremely important in what you said. You said something like "whenever you do it the unhealthy way you lose weight fast" - this implies you've had to do it multiple times. It implies that you may lose weight quickly initially, but the weight comes back on. This was also my experience - I could lose weight quickly by eating 1000 calories a day, but I could never keep the weight off.
You have to ask yourself, do you want short term success or long term success? You've experienced the short term success, did it really make you happy?
In July 2004 when I decided to change my life forever, I made a commitment to myself that I was changing how I ate to be HEALTHIER. Don't get me wrong, I loooove losing weight but when the scale didn't move on a certain weigh-in day, I told myself "I am doing great things for my body every day, weight loss is secondary to my ultimate goal of long term health." That change in mindset really helped me stay motivated through the hard times. All four of my grand parents died young - 2 of cancer, one of complications of diabetes and one of complications of alzheimer's. The genetic deck is stacked against me and the way I was eating was putting me on the express train to heart disease, cancer and diabetes.
I finally had to accept (and this was really really hard for me and took me 20 years) that I couldn't just diet for 2 months, lose 30 lbs and then go back to "normal" eating - muffins, full fat lattes, nachos, candy bars. I had to change my "normal." You gotta figure out what is YOUR new normal - what can you stick to (exercise 3 times a week? fewer fried foods? more steamed vegetables?) and what can you not stick to (giving up bread completely, exercising 2 hours every day?). A plan that is unique to you and sustainable over your life. For me, I could give up fast food and soda but not red wine
Congrats on your one year anniversary, I hope you guys go out someplace nice. Stay out of the bread basket, but you are definitely right to celebrate this important day. Figuring out what days were really important and worthy of celebrating (my birthday, Christmas dinner) and what days were not was a very important "maintenance" weight loss lesson for me. I finally figured out that one "off plan" meal did not mean I could have an offplan day or weekend or week - it meant MEAL. I had to get right back to my plan!
I think five lbs is a GREAT success! You are on your way! I like your hair too!
