Hi I know this is a teen board but I wanted to tell you what we have tried with our daughters. Both teens by the way. Our oldest has had the hardest time gaining weight. She doesn't like any of the supplements and really doesn't like milk. She says it makes her mouth slimey. She's not a big junk food eater either. No Mikey D's or Burger King. If you like the fast food places they are a great way to get in calories. My daughter does like Wendy's Frostee's though. A small frostee has about 340 calories. Thats the 12oz cup! She would eat one, two to three times a week. That popcorn chicken from KFC or Sonic, lots of calories. We tried looking for high cal, low quantity. Believe it or not, those Lean Cuisine's people eat, not so low in calories for what you get. My daughter would eat two Glazed Chicken's for an after school snack, that was 580 calories. We were trying to get in 3000 calories a day! Ice Cream. Dairy is good, get your calcium at the same time. Cheeses. I'm sure you've been told to get extra calcium already. Like I said, she isn't a junk food eater but Kudo bars are a pretty good snack. There's a recipe for a fortified shake if you like milk. If you are interested I will post it here. I try not to post here because it is for teens but I thought I might be of some help on this one. As Mom with two CF teens, I know the struggle that we all go through. You who I am sure is sick and tired of eat, eat, eat and maybe your parents too, tired of saying eat, eat, eat. My daughter said that eating wasn't enjoyable when you are always having to do it. That it got to the point to where she just didn't want to eat anymore. NOT that she was NOT going to eat, but that she was tired of focusing so much on it. She did not want a feeing tube, she told her docs that was out of the question, don't even bring it up. The doctors put her on Megase (Megesterol). She was on it for about 6 months, ate like a horse and gained weight. It is an appetite inducing med. used primarily for cancer patients and AIDS patients to help them to gain weight. It had not been tested for young children just young adults/teens. You might want to ask your doctor about it. Might it help you out? It is a type of steroid. She was not on it very long, then went off and on for about a year. Some people will gain the weight then lose it again when they stop taking it. She did not, the doctors were really happy with her weight gain, she was happy. I will say, she did not gain a ton of weight but she finally broke the 100lb mark. That was two and a half years ago, she was a freshman then, she is now finishing up her Jr. year, 5'5" and around 105 lbs Lastly, here are a few other ideas... Chicken nuggets/strips from any fast food place. KFC, Arby's, Sonic, Dairy Queen, and Chick-fil-A. Sonic and DQ both offer a country gravy to go with, that adds some more. To be honest all the fast food places, the burgers and fries. YOu don't want to eat them all the time. Milk Shakes and those Blizzards and stuff like that. Go slowly, don't try to eat alot, just try to eat high calorie. Enjoy the fact that you don't have to stay away from those enjoyable foods. I tell my girls to enjoy that they don't have to worry about not eating things that will "make them fat". And exercise, do physical activity, it helps build muscle, which weighs more than fat. One of the tough things though is to not keep eating the same thing all the time because then you will get tired of it and stop eating it. My daughter no longer eats the Frostees. If you like Mexican food, get a cook book and cook your own. Make your own soft tacos by buying corn tortillas, heat them up by dipping them in a shallow pan of hot oil, put in on a paper towel and pat both sides to get the excess oil off, put in your meat and/or cheese and what ever you like on a taco. YOu can do chicken, ground beef, shredded beef. You can make shredded beef by cooking a small roast in a slow cooker. Well it's time to get off to work. I hope that I have been of some help today. I didn't mean to ramble on and on. Liza(Mom of 2 CF teens)
