Professor Donal O'Shea, the HSE's National Clinical Lead for Obesity, has called for plans for calorie posting on menus to resume after they were postponed due to the Covid-19 pandemic.
Speaking to RTE's Claire Byrne, he claimed that 30% of people pay attention to calories and order items with less calories when such details are available on menus.
He revealed: "At a population level that is the change you can only dream of."
