But I don't think you are right. In fact, it's a good idea to stop eating junk food like hamburgers or drinking Coke. You'd better eat more fruit and vegetables. You should drink water instead of Coke. I think you can also make a plan for keeping fit and ask your parents' advice. They will agree with you if your plan is go- od enough.Don't ask for money from your grandparents. If you don't give up the bad eating habit,you will feel even worse. Hope things work out. Yours, Lily
