Knowsley council last night said tackling obesity was a “top priority”. Alongside the NHS, it is investing £1.5m to tackle it over the next five years.
A spokesman said “work was already under way” to address the committee’s recommendations, including an audit of school snacks.
He said: “Staff are considerate to the feelings of pupils in their care, and each school uses its own discretion as to the most appropriate changing set-up.
“We support schools in encouraging healthy eating options and schools do not promote unhealthy options or use them as incentives.”
Knowsley was one of the first UK councils to remove crisps and fizzy drinks from vending machines at its schools, 83% of which have national healthy schools status.
Councillors will be asked to back the recommendations on January 26 and submit them to the cabinet for formal approval.
