Understanding Syns and Natural Yogurt
For those following the Slimming World plan, understanding the 'syn' value of food is crucial for successful weight management. A Syn is a unit used to measure foods and drinks that are higher in calories, sugar, or fat and are not classified as Free Foods or Healthy Extras. The good news is that not all natural yogurts carry a syn value. The key differentiator is the fat content.
The Golden Rule: Fat-Free Natural Yogurt is Syn-Free
Slimming World's Food Optimising plan is designed to be generous and flexible, focusing on healthy, satisfying Free Foods that can be eaten in unlimited amounts. On this principle, fat-free natural yogurt is a prime example of a Free Food. This includes fat-free natural yogurt made from dairy, as well as fat-free natural Greek-style yogurt and skyr.
This is a huge benefit for slimmers, as it provides a creamy, versatile base for meals and snacks without using up valuable daily syns. You can enjoy a bowl topped with fresh fruit, use it as a base for marinades, or swirl it into curries for a rich, syn-free alternative to cream.
Why Other Yogurts Have Syns
The syn value of yogurt changes once it contains added fat or sugar. This is because these ingredients are higher in energy density and less filling than the protein-rich, fat-free versions. For this reason, full-fat natural yogurt and flavoured yogurts (even if they are fat-free) will have a syn value that needs to be factored into your daily allowance.
Slimming World's experts have found that many dieters would eat larger quantities of certain dairy-based foods, such as flavoured yogurts, which is why these items were given a syn value. The plan encourages members to make informed choices, and for yogurts, this means being mindful of the ingredients list.
What About Dairy-Free Natural Yogurts?
As of a few years ago, Slimming World also updated its guidance to include certain vegan options as Free Foods. Plain and unsweetened dairy-free yogurts, such as soya alternatives, are now also considered syn-free, offering more choices for those with dietary preferences or restrictions.
Syn Value Comparison Table: Natural vs. Other Yogurts
| Yogurt Type | Fat Content | Typical Syn Value (per 100g) | Notes |
|---|---|---|---|
| Natural Yogurt (Fat-Free) | 0% | 0 (Free) | Use freely as a topping or ingredient. |
| Greek-Style Yogurt (Fat-Free) | 0% | 0 (Free) | Also a Free Food due to high protein. |
| Natural Yogurt (Full-Fat) | Varies | Approx. 1.5 syns | Averages will differ by brand. |
| Greek Yogurt (Full-Fat) | Varies | Approx. 3.5 syns | Richer texture, higher syn value. |
| Flavoured Yogurt (Low-Fat) | Low | 0.5+ syns | Syns depend on added sugar and flavourings. |
| Skyr (Fat-Free) | 0% | 0 (Free) | A high-protein, creamy Free Food option. |
Homemade Syn-Free Yogurt Options
Making your own yogurt is another excellent way to ensure it remains syn-free and free of any hidden sugars or flavourings. With a basic yogurt maker or even just an insulated container, you can produce a batch of creamy, plain yogurt using a live culture starter and milk. This gives you complete control over the ingredients and guarantees a syn-free result. For those using an Easiyo maker, homemade soy yogurt can also be a low-syn or syn-free option, depending on the ingredients used.
For a naturally sweetened, syn-free alternative, you can flavour your homemade yogurt with natural vanilla extract or stir in some fruit to create a healthy, satisfying dessert or breakfast. This provides a great alternative to the pre-packaged, synned versions found in most supermarkets.
Conclusion: The Final Verdict on Natural Yogurt Syns
In summary, the number of syns in natural yogurt hinges entirely on its fat content and whether it's been a designated Free Food by Slimming World. The most important distinction to remember is that fat-free natural yogurt and fat-free Greek-style yogurt are 'Free Foods' and have no syn value. Full-fat or sweetened natural yogurts, however, will have a syn count that must be factored into your daily allowance. By choosing the right type of yogurt, you can enjoy this nutritious and versatile food without compromising your weight loss goals.

Frequently Asked Questions
What is a syn on the Slimming World diet plan?
A syn is a unit of measurement for food and drink that is high in calories or fat and is not a designated Free Food or Healthy Extra. Most members are allocated a daily syn allowance to use for treats and higher-energy foods.
Does Greek yogurt have syns?
Fat-free Greek-style yogurt is a 'Free Food' on Slimming World, meaning it has a syn value of zero. However, full-fat Greek yogurt is not a Free Food and does have a syn value that must be counted.
Are there any flavoured yogurts that are syn-free?
Generally, no. Flavoured yogurts, even fat-free ones, contain added sugar and therefore have a syn value. The syn value depends on the specific brand and flavour, so it's best to check the official Slimming World app for the exact amount.
Is homemade yogurt syn-free?
Homemade yogurt made with a live culture starter and fat-free milk or milk powder is typically syn-free, as it contains no added sugars or fats. This is an excellent way to ensure your yogurt is a Free Food.
Can I use fat-free yogurt to make a low-syn dessert?
Yes. Fat-free natural yogurt is a perfect base for a low-syn or syn-free dessert. You can sweeten it naturally with fruit or a syn-free sweetener, creating a guilt-free treat.
How can I check the syn value of a specific yogurt brand?
The most reliable way to check the syn value of a specific branded yogurt is to use the official Slimming World app or website, which has a barcode scanner and food search tool.
What's the difference between natural yogurt and Greek-style yogurt for syns?
Both fat-free natural and fat-free Greek-style yogurt are Free Foods and syn-free on the Slimming World plan. The difference lies in their texture (Greek yogurt is strained and thicker) and typically higher protein content, but not in their syn status when fat-free.
