Benjamin maintains a light diet with less meat and plenty of vegetables. In recent years, he has developed greater interest in cooking and learnt a lot about the proper amounts of ingredients and seasonings: when frying vegetables, he uses less oil and salt with grated ginger juice and ground garlic to enhance food flavour; when preparing salad dressing, he prefers using balsamic vinegar or lemon juice to oil; when making desserts, he uses low-fat milk as replacement for sugar and butter.

“Everyone's stomach has limited capacity. Eating smaller portions allows you to enjoy greater variety of food.” Benjamin usually takes light meals during workdays, e.g. tuna fish sandwich on whole wheat bread, smoked salmon salad and mixed fruit salad. At outdoor filming locations where BBQ meat lunch boxes are commonly provided, Benjamin usually opts to eat those prepared with skinless chicken breast only.
