The Senedd has voted to restrict meal deals in Wales after a vote on Tuesday.
The legislation will limit the promotion of unhealthy food items in supermarkets, including a ban on certain unhealthy items from meal deals and other multi-buy offers.
Free refills and top-ups of sugary drinks will also be banned under the legislation.
The Welsh government says the legislation will tackle obesity in Wales, but critics say it will make it harder for people with eating disorders.
The Food (Promotion and Presentation) (Wales) Regulations 2025 was backed by 25 votes to 24, with the aim of restricting “promotions that can encourage over-consumption”.
The latest figures from the National Survey for Wales show that 62% of the population over the age of 16 is overweight or obese.
Under the legislation, the in-store locations of foods that have high fat, sugar and salt content, will also be restricted.

Smaller businesses will be exempt, with the rules only applicable to businesses with 50 or more employees.
Eating disorder charity BEAT has previously warned the restrictions would make it harder for people with eating disorders to follow prescribed meal plans.
Jo Whitfield, the charity’s national officer for Wales, previously told Sky News that people with eating disorders risked “becoming even more unwell if they try and reduce the amount of calories they’re eating”.
The Welsh Conservatives, the Senedd’s largest opposition party, called the legislation “nanny state nonsense”.
Their shadow health secretary James Evans said it would “hit the poorest people in their pockets”.
He added that efforts to tackle obesity should be focused on providing support for sport in schools and at grassroots level and “encouraging more people to get active”.
