How Many Syns Are In 5 Maltesers? A Guide for Your Slimming World Plan

4 min read

Based on official product values, a 19.5g fun-size bag of Maltesers is 5 Syns, meaning each individual Malteser is approximately 0.5 Syns. So, how many syns are in 5 Maltesers, and how can you make them fit into your daily allowance without derailing your weight loss goals?

Quick Summary

Five standard Maltesers are approximately 2.5 Syns on the Slimming World plan. The value is calculated from the official Syn value of a fun-size bag, which provides a simple benchmark for tracking individual treats.

Key Points

  • Syns in 5 Maltesers: Five Maltesers are approximately 2.5 Syns, calculated from the 5-Syn fun-size bag.

  • Calculation Method: The easiest way to work out the Syns for a small number of Maltesers is to divide the total Syns of a fun-size bag (5) by the number of sweets inside (approx. 10).

  • Values Vary by Product: Different Malteser products, like cake bars or larger bags, will have different Syn values. Always check the specific product.

  • Moderation is Key: Maltesers can be easily incorporated into your daily plan by allocating some of your 5-15 daily Syns.

  • Enjoy Mindfully: To make your treat more satisfying, portion out your five Maltesers and savour them slowly.

  • Future Changes: From January 2026, the term 'Syns' will be replaced by 'Swips' on the Slimming World plan, though the tracking principle remains.

The Quick Answer: Syns for Five Maltesers

For those on the Slimming World plan, calculating Syns for small treats can often be a guessing game. Thankfully, with Maltesers, a reliable calculation can be made based on officially recognised values. Five standard Maltesers are approximately 2.5 Syns. This is a manageable and easily trackable value that can be incorporated into your daily Syn allowance.

How to Calculate Syns for Maltesers

Since Slimming World does not publish Syn values for individual chocolates, the most accurate method for working out the Syns in a small number of Maltesers is to use the declared value of a known bag size and perform a simple division. The 19.5g 'fun-size' bag is a perfect example, as it is officially counted as 5 Syns. A typical 19.5g bag contains roughly 10 individual Maltesers. By dividing the total Syns by the number of sweets, you get an approximate Syn value per Malteser:

  • Total Syns in fun-size bag: 5 Syns
  • Approximate number of Maltesers: 10
  • Calculation: 5 Syns / 10 Maltesers = 0.5 Syns per Malteser

Following this logic, five Maltesers would be 5 x 0.5, which equals 2.5 Syns. This method provides a consistent approach for tracking your sweet treats.

Other Maltesers Product Syn Values

It is important to remember that Syn values can vary between different Malteser products, such as larger bags, tubs, or special editions like cake bars. Always check the official Slimming World app or website for the most current information. Here is a comparison of some popular Malteser product values:

Product Approximate Size Syn Value Calculation Basis
5 Maltesers N/A (approx. 9.75g) ~2.5 Syns Fun-size bag calculation
Maltesers Fun-Size Bag 19.5g 5 Syns Officially listed value
Standard Maltesers Bag 37g 9.5 Syns Member-reported value
Maltesers Cake Bar Single Bar (approx. 24g) 6.5 Syns Member-reported value
White Maltesers 25g portion 6.5 Syns Member-reported value

Smart Swaps for Your Chocolate Fix

While a few Maltesers are a perfectly fine treat, if you find yourself regularly craving chocolate, there are some clever swaps you can make to save your Syns for special occasions:

  • Options Belgian Chocolate Drink: A single sachet is often just 2 Syns, offering a rich chocolate flavour for fewer Syns.
  • Sugar-Free Jelly: Many sugar-free jellies are incredibly low in Syns or even Syn-free, providing a sweet fix without impacting your daily allowance.
  • Low-Syn Hot Chocolate: Certain brands of instant hot chocolate, like Options, can satisfy your chocolate craving for a fraction of the Syns.
  • HiFi Bars: Some of the Slimming World HiFi bars are counted as a Healthy Extra 'B' choice, but others have a small Syn value for a substantial, satisfying snack.
  • Chocolate-Flavoured Quark: Using quark mixed with a little low-Syn chocolate essence and sweetener can create a creamy, high-protein dessert.

Making Maltesers Fit into Your Plan

The Slimming World plan is all about moderation and making informed choices. Fitting a small treat like Maltesers into your plan is entirely possible with a little planning:

  • Plan Your Syns: Allocate a set number of Syns for your daily treats. Knowing that five Maltesers are 2.5 Syns makes it easy to budget.
  • Savour the Taste: Don't just mindlessly eat them from the bag. Put five in a small bowl and really savour each one to feel more satisfied.
  • Combine with Speed Foods: Pair your small chocolate treat with a bowl of fresh fruit, like strawberries or raspberries, to add volume and fibre to your snack.
  • Use as a Topping: Crush a couple of Maltesers and sprinkle them over a Syn-free dessert, such as fat-free natural yogurt, for a delicious crunch.

A Note on the Future of Syns

As of late 2025, Slimming World has announced an update to its terminology. From January 2026, the term 'Syns' will be replaced by 'Swips' (Slimming World's Individual Picks). This change is intended to refresh the language and reinforce a positive mindset around enjoying treats in moderation. While the name is changing, the principle of accounting for higher-fat and higher-sugar foods remains the same. The calculation methods and the importance of tracking your daily allowance will still apply, just with a new name. This shows that the core philosophy of Food Optimising continues to be about choice and balance, not restriction.

Conclusion

Enjoying a few Maltesers as part of a balanced Slimming World plan is completely achievable. By calculating the Syn value accurately using the fun-size bag method, you can confidently treat yourself without guilt. Remember that moderation and planning are key to weight loss success, and a small, planned treat can help you stay on track and feel less deprived.
