Fianna Fáil's spokesperson on Justice, Children and Youth Affairs has warned that childhood obesity in Ireland is likely to rise without State intervention.
Senator Lorraine Clifford-Lee says it is a lower-socio-economic environment that is a problem from getting worse.
It follows the latest Growing Up in Ireland study released earlier this week which found that 22% of Irish nine-year olds are overweight or obese.
The study, conducted by ESRI and Trinity College Dublin, was found that only a quarter of a year-old recommended level of physical activity is at least 60 minutes every day.
The surveys, tracks more than 7,500 children and their families, indicated that most children were a healthy weight but 17% were overweight and 5% were obese.
Senator Clifford-Lee also said parents must set an example and take responsibility to encourage children to make healthy choices.
