My DD's who are 12 and 13 are actually working on this right now. They have not used the feeding tube in almost a yr. Instead they have been drinking the cans. I have my phone alarms set to "can times" which is generally right after a meal. The 13 yr old drinks 5 cans a day the 12 yr old drinks 4. So far we have had pretty good weight gain and they are much happier. Eating for my 13 yr old has always been a huge battle. Now we don't fight her because we know she will get a can after the meal, so she doesn't fight us as much on eating. Also adding Carnation instant breakfast to the drinks have helped but they can be a little expensive.
