Slimming World has announced it will rename its controversial 'Syns' system to 'Slimming World Individual Picks', or 'Swips', as part of a broader effort to modernise its language and focus on health. The term, introduced in the early 2000s to describe foods low in nutritional value and high in calories, has faced criticism for implying guilt or sin associated with eating.
Managing Director Lisa Salmon said the change responds to feedback that the word 'Syn' suggested shame, which she said was never the organisation's intention. 'We recognise the power and impact of words,' Salmon stated, adding that the rebrand aims to make everyone feel welcome.
Alongside the name change, Slimming World is updating its Food Optimising plan to include healthy fats such as nut butters and avocados, which were previously high in Syns. These will now be part of a new 'Healthy Extras' category, alongside existing calcium and fibre choices, allowing dieters to select daily portions of nutrient-rich foods.
The weight-loss organisation, founded in Alfreton, Derbyshire, in 1969, emphasised that its core methods remain unchanged. Salmon noted that the weight management industry has evolved significantly, particularly with the rise of weight loss medications, but insisted lifestyle-based solutions like Slimming World are more important than ever.
The changes will take effect from January 2026. The announcement follows the death of founder Margaret Miles-Bramwell in February at age 76.
