1. My diet is food-restrictive.
Yes. When I changed my life in July 2004, I gave up: fast food, sugary soda, packaged baked goods, most fried foods, foods in cream-based sauces, most candy. I severely limit the following: alcohol, desserts, ice cream, cold cereal, the occasional piece of fine dark chocolate, cheese (mostly because it hurts my stomach these days. I honestly do not miss these foods at all - switching to whole foods eliminated most of my crazy food cravings.
2. My diet will work in variable situations for the rest of my life (holidays, parties, etc.)
Absolutely. My plan is basically whole foods + calorie counting. It is flexible, allowing occasional treats. I understand that I will occasionally eat offplan, I just have to immediately get back on plan. I have been maintaining my weight within 5 lbs for over 2.5 years and it has included holidays, vacations, 5 course dinners and extremely fancy restaurants (with course by course wine pairings!).
3. My diet is well known.
No.
4. I made my own diet up for myself.
Yes. In my opinion the only diet that will work for a particular individual is a diet that is created by that individual. I am the only one who knows I can live without fast food but I can't live without an occasional glass of red wine. I am the only one that knows I can eat baby carrots/red pepper strips/grape tomatoes and sugar snap peas for a snack every day but I need to split dessert in a restaurant once a week with friends.
5. I try not to let others know that I am making these lifestyle changes.
Ha. No. All of my family, friends, coworkers know about my "super food diet." I lost nearly 75 lbs and people ask all the time how I did it.
6. My whole family is taking part in aspects of my lifestyle changes.
N/A
7. I am better able to handle temptations since I began my changes.
Some days are better than others

I am very good about my "NO'S" but I succumb to temptation occasionally (ate a surprise piece of baklava today, heh). But hey - I am human, it will happen. I made my healthy dinner for tonight and MOVED ON.
8. I am still struggling to get it right.
No. I feel very comfortable with my new healthy way of eating. I do have the occasional "oh wow, you really ate a lot of cheese and crackers at the company meeting" but I accept that I will occasionally eat offplan. I try to make 90% of my choices GOOD choices.
9. I am losing weight at a rate I am happy with.
I lost the first 55 lbs in about 7 months. It took me another 9 months to lose the last 15 lbs. Overall, I was very happy with the rate of loss and my eventual end weight.
