Slimming World has announced it will scrap the term 'Syns' from January 2026, replacing it with 'Swips' (Slimming World Individual Picks) as part of a rebrand aimed at making the diet plan more inclusive. The change follows a review of language and terminology used by the weight-loss organisation.
Under the new system, unhealthy foods high in energy density—such as alcohol, crisps, chocolate and butter—will be referred to as Swips. The company said the word 'Syns' could be misunderstood or act as a barrier for some people seeking support to reach a healthy weight.
In addition to the terminology change, Slimming World will introduce healthy fats like avocado, nuts and seeds into its 'Healthy Extras' category. Previously, these foods were counted as Syns or included in free foods. Members will now be able to choose three Healthy Extra portions daily from calcium, fibre and healthy fats options, with at least one calcium choice recommended.
Managing director Lisa Salmon said: 'Language matters and we know Syns can be misunderstood or be a barrier for some people... We want everyone to feel welcome at Slimming World.' She emphasised that no food has ever been banned, and the move aims to increase understanding of healthy eating.
The plan continues to offer 'free foods'—lower energy density items such as lean meats, fish, eggs, beans, fruits, vegetables, grains and pasta—that members can eat freely. Slimming World said the changes reflect the latest science and member feedback, ensuring the programme remains effective in the era of weight-loss medications.
