Sisley’s mother is good at cooking and always ensures healthy diet for her family. Years ago, she already started to cook 10-grain rice with oatmeal and brown rice, and started making dietary changes such as substituting rice with sweet potato. She prepares meals with less meat and more vegetables, and limits her use of oil and salt.

After becoming a full-time actor, Sisley rarely eats regular meals and eats takeaway lunchbox for lunch most of the time. To supplement dietary fibre and other nutrients, she consumes plenty of vegetables. She also opts for light-flavoured vermicelli and noodles in soup at times. Besides, Sisley likes to try different kinds of healthy dishes.
