问：你的朋友Joe 为了迎接高考努力学习，近来病倒了。请你以医生的名义给她写一封信。

Dear Alice,
I am very glad to receive your letter, depending on your current situation, first, the best way to lose weight is to do sports to lose weight, but you have to persevere. Besides, you should quit eating snacks. Second, to plan your own exercise program, make recipes and calculate the daily intake of calories is good for yourself. Last but not least, rest, to maintain an optimistic mood， appropriate vitamin supplements. Wish you healt.
