Ms Sim Hui Churn quit her job as a lab supervisor to become a zumba instructor last year.
Zumba instructor Sim Hui Churn is a healthy 50kg now, but four years ago, she weighed nearly twice that.
Working in a sedentary job then and not watching what she ate resulted in her tipping the scales at almost 90kg.
She had been too tired from work to make healthy lifestyle changes, and instead tried a slimming programme in 2011.
Ms Sim, 40, lost more than 30kg – but she gained back the weight within a year.
She realised she needed a bigger change. Urged by family and friends to live more healthily in the light of health risks such as diabetes and heart disease, the then lab supervisor in a factory signed up in 2013 for the Health Promotion Board’s (HPB) Lose To Win programme and other exercise classes concurrently.
