Former Miss Hong Kong Kayi Cheung, also a nutritionist, has a secret to healthy living - "One less and Three more" meaning eat less but eat more often, do more exercises and learn more about food labels. She has been a health advocate since early age and a genuine supporter of the "less oil, salt and sugar plus plenty of fruits and vegetables" principle under the EatSmart Campaign.

Kayi has developed the habit of reading food labels since she was a young girl, which was apparently one of the reasons for her choice to study nutritional sciences. To be a smart-eater, she believes, one should not be easily convinced by the promotional claims of food items. Food choices can be made much easier with better understanding of the Ingredients of food, especially the calorie counts, sugar as well as fat contents. For instance, 100% natural fruit juice are generally preferable to sugared soft drinks, yet they are no substitute to fresh fruits, which contain high dietary fibre. Kayi assures that it is not difficult or time-consuming to learn the food labels.

Apart from eating plenty of veggies and less meat, Kayi does three one-hour sessions of physical exercises a week. She said, "Eating is part of our life. It is closely linked to various aspects of our daily life. If we could maintain a well-balanced diet and regular exercise, eating is always an enjoyable thing to do".
