Scottish Slimmers has gone bust, leaving thousands of members out of pocket and more than 30 employees out of work.
The organisation, which operates 140 branches around the country, confirmed that it ceased trading as of midnight on Friday.
Around 30 headquarters employees and coaches across the nation have been left out of work after all Scottish Slimmers classes were suspended.

Refunds on membership passes cannot be provided but the firm said that all existing members affected will be given free access to the Scottish Slimmers online service instead.
Amanda Boyle, chief executive of Scottish Slimmers Ltd, said it had “become impossible to sustain a model where the costs of running the class network are twice the level of the annual revenue generated by these classes”.
She said: “This has been an incredibly difficult decision to make as I know how much the network of classes means to our members and how our community of members has valued the support of their class coaches in their healthy living and weight loss programmes.
“Many of our coaches have years of enthusiastic and loyal service and I understand that this decision is a very difficult one for them.”
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
