If you're interested in combining shakes into your slimming world diet, you might be wondering how many syns shakes have and if they are slimming world friendly?

Cambridge shakes from the Cambridge Weight Plan have on average 10 syns a serving, making them very high in syns and therefore should be consumed within moderation.
In our guide below, we will take you through why Cambridge shakes are so high in syns, some syn values plus some low syn alternative shakes from other brands for when you need a quick and easy meal.
At 10 syns a sachet, Cambridge shakes are very high in syns, taking up the majority of your 15 syn daily allowance.
These shakes are high in syns since they are formulated to replace a meal, and therefore have the calories of an average low cal meal, which is around 200 calories a sachet.
Although high in syns, switching out a meal with a shake can help weight loss if you struggle to find the time to cook healthy meals three times a day, we would not however have them as a snack due to their high syns.
We would also suggest having shakes in moderation since they do not have a lot of nutritional benefits other than some being high in protein.
Cambridge shakes all have a similar syn value no matter the flavour you choose, to help you stay on track, we've listed their general syn values down below.

If you find Cambridge shakes to be too high in syns, but still like having a shake to replace one of your meals or as a snack, we've got some great shake alternatives for you down below.

To conclude, Cambridge Shakes are very high in syns, having 10 syns a sachet, however these high syns are because the shake is formulated to replace a meal, so needs to give enough calories in order to sustain your energy.
Shakes can be a great way to boost weight loss by switching out one of your meals, but we would suggest having them in moderation due to their high syns and lack of nutritional benefits.
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.
