Representative Fianna Fáil on Justice, Children and Youth Affairs warned that obesity in childhood in Ireland is likely to increase without state intervention.
Senator Lorraine Clifford-Lee says it is crucial that larger resources are targeted at lower socio-economic schools and communities in order to make the problem worse.
This is followed by the latest Growing Up study in Ireland published earlier this week, which showed that 22% of Irish nineteen years of age are overweight or obese.
A study conducted by ESRI and Trinity College Dublin found that only a quarter of nine-year-olds achieved the recommended level of physical activity, which is at least 60 minutes a day.
A survey of more than 7,500 children and their families showed that most children are healthy and 17% are overweight and 5% obese.
Senator Clifford-Lee also said that parents should set an example and take responsibility for promoting children to a healthy choice.
