Best Greek Yogurt on Slimming World (Ranked)
Greek yogurt might just be the single most useful food you can keep in your fridge on Slimming World. I say that having been on plan for a while now, and I mean it genuinely rather than as a content opener. It's thick, it's filling, it's high in protein, and when you choose the right one — it's completely Free.
The difference between the right and wrong Greek yogurt is significant. Pick a 0% fat option from the right brand and you can eat a 170g pot without spending a single syn. Pick a full-fat version without thinking and you could be looking at 4 syns for the same size serving. That's a meaningful gap when you're trying to make the most of your daily allowance.
What I love most about Greek yogurt is how many jobs it does in the kitchen. I have it for breakfast with fresh fruit and a small handful of granola (synned separately). I use it instead of crème fraîche in pasta sauces — it works brilliantly, especially in a chicken and mushroom dish. I thin it down with a splash of water and a pinch of garlic powder for a quick dip. I dollop it over fruit crumble instead of cream. Once you start using it this way, you wonder how you ever managed without it.
But not all Greek yogurts are created equal, and not all of them are Free. Some are 'Greek style' rather than genuine strained Greek yogurt, which affects texture. Some have added sugar. Some are fat-free in name but still have syn values due to other ingredients. I've ranked the six best options below so you can pick the right one for your goals, your taste, and your plan.
Whether you're looking for the highest protein, the lowest syns, a plant-based option, or just the creamiest texture you can get away with on a Friday night, there's something on this list for you.
The rankings
Fage Total 0% Greek Yogurt
170g pot
The gold standard of 0% Greek yogurt on Slimming World. Properly thick, properly creamy, and completely Free. Made by genuine straining rather than thickening agents, which gives it that dense, satisfying texture that holds up in cooking as well as eating straight from the pot.
- Completely Free on Slimming World
- Very high protein — around 17g per 170g pot
- Thick, dense texture that works in cooking and as a dessert
- Widely available in most major supermarkets
- Can taste slightly sharp or sour plain if you're new to 0% fat yogurt
- Slightly pricier than supermarket own-brand options
Yeo Valley 0% Fat Greek Style Natural Yogurt
150g
A Free option with a slightly softer texture than Fage. Yeo Valley is organic, which matters to some people, and the flavour is gentle and a little less tangy. It's lovely with honey (synned) or stirred into overnight oats. The protein is lower than Fage but it's still a solid Free choice.
- Completely Free on Slimming World
- Organic certification
- Gentler, milder flavour — good for those who find Fage too sharp
- Works well layered with fresh fruit
- Lower protein than Fage — around 10g per 150g versus 17g
- Softer set, less useful as a cooking substitute for crème fraîche
Alpro Plain No Sugars (Soya Yogurt Alternative)
125g
The best plant-based option for Slimming World members. It's Free, unsweetened, and made from soya so it has a decent protein profile compared to most other plant yogurts. Texture is slightly thinner than dairy Greek yogurt but it works well in smoothies, sauces, and as a breakfast base.
- Completely Free on Slimming World
- Suitable for vegans and those avoiding dairy
- Works well in cooking and baking
- Widely available
- Lower protein than dairy options — around 5g per 125g
- Texture is noticeably thinner than Fage or Yeo Valley
- Flavour is distinctly different from dairy yogurt
Chobani Non-Fat Plain Greek Yogurt
150g
Technically not Free, but at half a syn per serving it's so close that most members barely notice the difference in their daily total. Chobani has an excellent thick texture — it's an American brand that's gained a strong following in the UK, and for good reason. The flavour is clean and not overly sour.
- Excellent thick, creamy texture
- Strong protein content
- Widely stocked in Tesco, Sainsbury's and Waitrose
- Half a syn per serving — not technically Free
- Slightly more expensive than Fage in some stores
Liberté 0% Plain Greek Yogurt
150g
A French brand with a genuinely luxurious texture that feels more indulgent than its calorie count suggests. It's 1 syn per serving, which puts it below most full-fat options but above the Free tier. If you want something that feels like a treat and you have a syn to spare, this is a very pleasant option.
- Rich, indulgent texture for a 0% product
- Tastes great plain without needing anything added
- Lower calorie count keeps it relatively diet-friendly
- 1 syn per serving — not Free
- Less widely available than Fage or Yeo Valley
- Premium price point
Fage Total 2% Greek Yogurt
170g pot
The full-experience option for when you want the real thing and have the syns to spend. The 2% fat content makes a noticeable difference to the texture and taste — it's richer, silkier, and more satisfying than the 0% version. At 4 syns for a pot it's not an everyday choice, but as an occasional treat or when you're entertaining, it's hard to beat.
- Exceptional taste and texture — genuinely satisfying
- High protein content despite the higher fat
- Worth the syns as an occasional treat or for guests
- 4 syns per pot is a significant portion of your daily allowance
- Not a practical everyday choice if you're syn-conscious
- Easy to eat more than one portion
How we ranked these
I've ranked these primarily by Slimming World value — Free options come first because that's what most of us are looking for. Within the Free tier, I've ordered by protein content, since protein is one of the things that makes Greek yogurt genuinely filling rather than just a low-syn treat. Syn values are based on standard portion sizes using current Slimming World guidance; always verify in the app as values can be updated.
Frequently asked questions
Which Greek yogurt is Free on Slimming World?
The key thing to look for is 0% fat and no added sugar. Fage Total 0%, Yeo Valley 0% Greek Style, and Alpro Plain No Sugars are all currently Free on Slimming World when eaten as a meal accompaniment or standalone food. Syn values can be updated by Slimming World at any time, so it's always worth checking the official app or website before you buy, especially if you're trying a new brand or supermarket own-label product for the first time.
Is Fage Total 0% Free on Slimming World?
Yes — Fage Total 0% is Free on Slimming World, which is one of the reasons it's become such a staple for members. A standard 170g pot contains around 97 calories and approximately 17g of protein, making it one of the most nutritionally generous Free foods on the plan. It's worth noting that Fage Total 2% and Fage Total Full Fat are not Free and carry a syn value, so always double-check you're picking up the 0% version when you're shopping.
Can I use Greek yogurt instead of cream or crème fraîche in recipes?
Yes, and this is honestly one of the best syn-saving tricks on the whole plan. Full-fat crème fraîche can cost you 3 to 4 syns per tablespoon; swapping it for Fage Total 0% costs nothing. The trick is not to let the yogurt boil, as it can split at very high temperatures. Stir it in off the heat or on a low simmer, and you'll get a creamy, slightly tangy sauce that genuinely rivals the full-fat version. It works particularly well in chicken dishes, pasta sauces, and dips.
What is the lowest-syn Greek yogurt?
Several 0% fat Greek yogurts are completely Free, meaning they have 0 syns rather than just a low syn count. Fage Total 0%, Yeo Valley 0% Greek Style, and Alpro Plain No Sugars all fall into this category. Among options that do carry a small syn value, Chobani Non-Fat Plain is one of the closest to Free at around half a syn per serving. The key pattern is: 0% fat plus no added sugar almost always equals Free, but always verify in the Slimming World app as formulations do occasionally change.
Is Greek yogurt good for weight loss?
Greek yogurt is a genuinely excellent food for anyone trying to lose weight, and not just because of its syn value on Slimming World. The high protein content — particularly in strained varieties like Fage — supports satiety, meaning you feel fuller for longer after eating it. Protein also requires more energy to digest than carbohydrates or fat, which has a small but real impact on overall calorie balance. The fact that the 0% versions are Free on plan means you can eat them freely without worrying, which removes one of the biggest barriers to building consistent healthy habits.
