Dear Fai Fai,

How are you? I'm glad that you want to lose weight. If you want to be healthy, you have to listen to me.

First of all, you shouldn't eat 5 big bowls of rice every meal. You need to eat grains, vegetables and meat in the 3:2:1 ratio. Besides, you must drink six to eight cups of water every day. I think it is OK to drink one to two cans of coke a week but drinking four cans of it a day is too much because coke contains a lot of sugar.

You said you like watching TV. Why don't you skip and watch TV at the same time? And you should go jogging in a park with your friends.

All of these are good for your health. You ought to follow my advice and keep doing them.

I'm waiting for good news from you.

Yours sincerely,

Dr Chan (text edited)
