Hi Joan and Vicki,  
I saw the show and knew exactly what Vicki was going through. I too am a single mom with an over weight 12 yr old son. I don't have a lot of advice to give, just some tips that might make things a little easier for Vicki because of her busy schedule. I also have my son seeing a pediatric dietition, so he is on a balanced eating plan (1800 calories a day). I have also enrolled him in an excercise program that he does for 45 minutes twice a week. So far he has lost 8 pounds in the course of a month. Unfortunately my mom passed away 5 yrs ago, but I know if she were here, she would be saying the same things your mom is saying.  
 
 
 
Here are some things that I do on the weekends to make my life easier during the week, and to make sure he stays on his eating plan. I peel and section about 6 oranges and put them in snack size zip lock baggies and keep them in the refrigerator. I put a half of a sectioned orange in each baggie, it fits perfect, and is a perfect serving size. With 6 oranges, you get 12 servings.  
 
I rinse off grapes and carrots and put them in individual snack size zip lock baggies too (about 15 to 20 per serving). I try to buy as many kid friendly vegetables and rinse and cut them up in bite size pieces and put them in the snack size baggies as well. The ones that he prefers is red peppers (they are sweeter then green), baby carrots and celery. I usually cut the peppers and celery in sticks. Then I use Light Hidden Valley Ranch sour cream dip when we wants to snack on the veggies. I keep that in a container in the refridgerator. I also buy skim string cheese, and let him have that with a fruit after school for a snack. Whenever I buy watermelon or any kind of melon. I cut it up in bite size pieces and either put it in the serving size baggies, or in a container in the refridgerator depending on how much time I have. It really makes my life easier during the week when I'm in a hurry.  
 
 
 
I also keep a basket of already rinsed off fruit on the kitchen counter. I have found that as long as all he has to do is grab it, open it and eat it, then he won't ask me for unhealthy snacks that he can simply open and eat, like chips or cookies. There are times that I let him have chips and cookies, but I choose the more healthier ones, like baked chips and low calorie cookies, but I don't keep them in the house, so the only time he has access to them is when we go out. I use my slow cooker a lot during the week so when I get home, dinner is finished and there is not much clean up. It's a good investment because you can find a lot of healthy slow cooker recipes online. I also found a lot of kid friendly fish recipes that are quick and easy. I can send you some of the recipes if you want them. My email address is diane731@comcast.net  
 
 
 
It takes time and effort to get a child at that age to stick to a good balanced eating plan, and get them on a schedule to make sure they are getting proper excercise, but it can be done. I personally never thought I would be able to get my son to eat fish, but the recipes that I have found are great! I found a lot of them at www.allrecipes.com You can find good recipes there and make them low calorie just by making some changes in the ingredients.  
 
Just by having my son on this eating plan, me and my 16 yr old daughter have lost weight too. The key is to just be patient and make some small changes around the house. I'm sure the people that Dr. Phil has set you up with will have a good plan for your daughter. I just hope some of these tips help with your busy schedule. Please don't hessitate to email me if there is anything I can help you with. I will be more then happy to. You have a beautiful daughter, and once she starts to lose a few pounds, she will get so excited and motivated that it will make things a little easier. You have been blessed with a beautiful daughter and a wonderful mom who loves the both of you very much, so please cherish the time you have together, you'll be glad you did.  
Sincerely, 
Diane
