If you are looking to make shakes a part of your slimming world diet, you will need to make sure you are synning them, since there are no syn-free shakes on the plan.

Herbalife shakes in particular have 5 syns a shake, making them fairly low in syns, but it should be noted that these cannot replace a meal, due to their low calorie content.
We've discussed in further detail below why Herbalife shakes have syns, syn values of Herbalife shakes plus some low syn alternatives from other brands.
Since shakes are typically advertised as being healthy, you might be confused as to why Herbalife shakes have so many syns. This is because their ingredients are not syn free, having around 5 syns a serving, this means you could have up to three shakes before using up all of your daily syn allowance.
Herbalife shakes have around 90 calories each, so we would not recommend having them as a meal since they are not high enough in calories, they would only be suitable as a snack.
Herbalife shakes come in many different flavours, to keep you on track with your syns we've listed all their syn values down below.

Overall, Herbalife shakes have around 5 syns for one serving, which doesn't make them too high in syns, but we would only recommend having these shakes as a snack since their calorie content is not high enough to replace a meal.

Some shakes which are higher in calories can be used as a meal replacement to help you lose weight, but the syns might be higher too.
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.
