Soya yogurt on Slimming World: The Free Food Rule Explained
For anyone following the Slimming World plan, particularly those who are vegan or have a dairy intolerance, the clarification around soya yogurt was welcome news. The key distinction, as confirmed by Slimming World itself, lies in whether the yogurt is plain and unsweetened. In a shift that aimed to better support its vegan members, the organisation added plain, unsweetened dairy-free soya yogurt to its extensive list of Free Foods. This means it can be enjoyed as part of a meal or as a snack without the need to weigh, measure, or count Syns. This move aligns with the core principles of Food Optimising, which encourages filling up on satisfying, low energy-density foods.
Why flavoured and sweetened soya yogurts have Syns
While the plain, unsweetened variety is a Free Food, any soya yogurt that is flavoured or contains added sugar will carry a Syn value. This is because Slimming World's Food Optimising strategy is based not just on calorie counts, but also on energy density and how satisfying a food is. Sweetened items, including flavoured yogurts, are generally less filling for the same number of calories and are often consumed as a snack rather than part of a meal. For example, community posts from 2025 indicated that specific flavoured Alpro products, such as their Greek-style or vanilla yogurts, have a Syn value due to their sugar content. It is crucial to check the specific product and its nutritional information to determine the correct Syn value, as this can vary widely between brands and flavours.
Finding the right soya yogurt for your plan
With so many different products on the market, it can be confusing to know which one to choose. The simplest rule is to look for the words 'plain' and 'unsweetened' on the packaging. Any other description, such as 'vanilla', 'fruit', or 'honey', will likely incur a Syn penalty. For those who prefer a sweeter taste, adding Free fruit like berries or a sweetener is an excellent way to flavour plain soya yogurt without adding Syns. For those who choose to use Syns on a flavoured pot, consulting the official Slimming World app or online database is the most accurate way to find the correct value.

Practical tips for enjoying soya yogurt on Slimming World
- Flavour it yourself: Instead of buying a pre-flavoured yogurt, start with a plain, unsweetened pot and add your own toppings. Free options include fresh or frozen berries, apple, pear, or chopped mango. A sprinkle of cinnamon or a few drops of vanilla extract also works wonders without adding Syns.
- Create a Free Food breakfast: Mix plain soya yogurt with a portion of your Healthy Extra B choice, such as oats or bran flakes, and top with plenty of fruit. This makes for a filling and nutritious start to the day.
- Use it in savoury dishes: Plain soya yogurt can be used as a fantastic low-Syn alternative to sour cream in curries, soups, and dips. It adds a creamy texture without the high fat content of dairy alternatives. Just be sure to use it to finish cooking rather than boiling it for a long time, which can cause it to split.
- Make frozen treats: For a refreshing snack, you can create a Syn-free frozen yogurt bark. Simply spread plain soya yogurt onto a lined baking tray, sprinkle with your favourite Free fruits, and freeze until solid.
- Consult the app: The Slimming World app and website provide the most up-to-date Syn values for specific branded products. Always double-check before buying flavoured varieties to ensure you are accurately counting your Syns.
