Skittles, my suggestions is to not look at weight loss as a diet. Think of it as a life-style change. The weight won't come off over night and if you want to keep it off when you get there, you need to have retrained yourself to live in that lifestyle.
The fries aren't going anywhere. They will be there for the rest of your life - now, while you are losing weight and when you are there and maintaining your weight. My thought is that you have to learn to live with them. That might come off a persnickity but that's not how it is meant. You can still have them, just have to learn when its okay and how often.
Do you have someone that you admire for a healthy lifestyle of weight loss or weight maintence? What I would suggest is that you try to emulate that person and learn all you can about living with unhealthy and tempting foods.
You can do it! You have to believe in your mind that you can and then begin to live it out. And then take it day by day. It won't happen overnight so don't get down on yourself if you do enduldge. Remember, it's a lifelong journey.
