A spokesman for Fianna Fáil about Justice, Children and Youth Affairs has warned that obesity in Ireland is likely to increase without State intervention.
Senator Lorraine Clifford-Lee said it was important that greater resources be targeted at schools and lower socio-economic communities to prevent problems from getting worse.
This follows the latest Growing Up study in Ireland released earlier this week which found that 22% of Irish people aged nine years were overweight or obese.
The study, conducted by ESRI and Trinity College Dublin, found that only a quarter of nine years reached recommended physical activity levels that were at least 60 minutes every day.
The survey, which tracks more than 7,500 children and their families, shows that most children are healthy weight but 17% are overweight and 5% are obese.
Senator Clifford-Lee also said parents should set an example and be responsible for encouraging children to make healthy choices.
