A bottle of ketchup is a staple in many of our kitchens, accompanying chips, eggs, pizza, you name it, but on the slimming world plan, can you have ketchup? Or is it high in syns?

Ketchup on average has 1 syns for a 15g tablespoon, making it low in syns, but should be used within moderation, we recommend weighing it out or measuring the condiment to stay on track with your syns.
In our syn guide below, we will discuss why ketchup has syns, some syn values of ketchup and some low syn alternative condiments for dipping or as a side.
At around 0.5 syns to 1 syn for a 15g tablespoon, you might be wondering why ketchup has syns on the slimming world plan? Most ketchup has syns due to the high sugar content, having nearly 3g of sugar for just one tablespoon.
You could have up to 15 tablespoons of ketchup before using up your daily syn allowance, therefore we would suggest not using squeezy ketchup over your food since you can end up using more ketchup than you think.
In terms of the type of ketchup, many of us pick Heinz ketchup as a staple over other brands, this type of ketchup also has 1 syn a tablespoon, making it low in syns, but should be used in moderation since it also contains 3.5g of sugar for just a spoon.
To save syns you could always use their reduced sugar version which only has 0.5 syns a tablespoon instead.

To conclude, ketchup is typically low in syns, having around 1 syn a tablespoon, to reduce syns we suggest opting for lower per cent sugar options which often have fewer syns, around 0.5 syns a serving.

Syn values are calculated using a formula based on calories, saturated fat and sugar content per serving. They’re not the same as calories — a product can be low in calories but higher in syns if it’s high in sugar or fat. Always check the official Slimming World app for the most accurate and up-to-date syn values.
Yes. When manufacturers reformulate their products, the syn value can go up or down. This is why we recommend double-checking with the Slimming World app or your consultant, especially if a product’s packaging has changed recently.
Most Slimming World members work with 5 to 15 syns per day. Your consultant will advise on the right amount for you. The key is to use your syns on the things you enjoy most — whether that’s a chocolate bar, a glass of wine, or a packet of crisps.
