She was aware of the benefits of healthy cooking, but did not do it often at home as she thought it was inconvenient.
At most, she would eat brown rice instead of white rice.
At a workshop yesterday, Miss Tan Wen Yan, 30, learnt much more about healthy cooking.
Along with 119 other participants at Mapletree Business City (MBC), she learnt how to select healthier ingredients and to put together a simple yet tasty low-calorie meal.
The workshop was conducted by celebrity health coach Jacelyn Tay from health-care and wellness clinic Body Inc and raw food chef Bibiana Neo.
The pair demonstrated how to make zucchini noodles with pesto, which has only 142.8 calories.
Amazed at its simplicity and innovation, Miss Tan said: "I was surprised that zucchini could be used to make noodles. It tasted quite good."
The workshop is one of many that the Health Promotion Board (HPB) has organised with MBC as part of the Healthy Workplace Ecosystem initiative.
The initiative, which was launched last October, involves exercise programmes, healthier food options and screening packages.
MBC has also implemented healthier food options at eateries to complement the workshops.
Miss Alcina Lin, 25, who works at MBC, tried out some of these options.
She participates in the workshops as she is health-conscious.
Miss Lin said: "Having healthier alternatives is good as more people will choose them."
She and her colleagues often choose the healthier options at the Food Style Food Court during lunchtime.
Said Miss Lin: "I enjoy the sliced fish soup. The soup is lighter, but still tasty. I will make the conscious choice to eat the healthier options."
