The Royal College of Physicians (RCP) has accused the Welsh Government of making "little or no progress" on tackling obesity in Wales.
The comments come as the government lays out its draft strategy to prevent and reduce obesity following a public consultation.
The RCP claimed the government's draft plans do not go "far enough" and do not explain how it aims to help those who are already obese.
RCP Cymru Wales say it wants people with obesity to have better access to specialist treatment and for each health board to appoint an obesity lead.
It says the Welsh Government should hold health boards to account over their duty to provide a full obesity treatment pathway.
A Welsh Government spokesperson said it welcomes the Royal College of Physicians' contribution.
The consultation closes today and the final strategy will be published in October.
