In a statement to FMT, Dr Dzulkefly said that any changes to the operating hours of eateries should consider the needs of those who rely on them, such as shift workers like police officers and doctors.
He said one in three Malaysians have low health literacy, adding that closing 24-hour eateries would not necessarily lead people to choose healthier alternatives.
Dr Dzulkefly said a proposal will be prepared for review by the Health Ministry and the government to determine the next steps.
