Sugar-Free Snacks Under 100 Calories:
Your Complete Guide
Everything you need to know about low-calorie, sugar-free snacks, from how sweeteners work to which products hit under 100 calories per portion
What Are the Best Sugar-Free Snacks Under 100 Calories?
Yes, you can enjoy genuinely sweet snacks under 100 calories with no added sugar. The key is choosing products made with sweeteners instead of sugar and understanding how to read a portion size. Here is what the data shows:
- +Diablo SF Gummy Bears (20g serving) deliver approximately 44 kcal with 0.02g sugars, sourced from verified nutritional data
- +Diablo SF Butter Sweets (3 pieces, approx. 12.3g) provide around 33 kcal, made with sweeteners instead of sugar
- +Diablo NAS Apricot Muesli Bar (full 30g bar) contains 98 kcal, with added vitamin D, folic acid and iron
- +Diablo NAS Milk Chocolate 85g (one serving, 14g) delivers 71 kcal per serving with 1.2g sugars, and the sugars occur naturally from milk solids
- iSugar free and no added sugar are different claims. Understanding the distinction helps you choose the right product for your goals
You have cut back on sugar. You have swapped the biscuit tin for better habits. And then 3pm arrives and the craving hits. The good news: finding low calorie sugar free snacks that actually taste like something is no longer a compromise.
The sugar-free confectionery category has matured considerably. Products sweetened with polyols such as maltitol, isomalt, and sorbitol now deliver the flavour and texture of conventional sweets, gummies, chocolates, and wafers, at reduced calorie counts and with no added sugar.
This guide covers everything: what sugar free actually means under UK and EU food law, how polyol sweeteners work, which Diablo products sit under 100 calories per portion, how to read a nutrition label correctly, and practical snacking strategies for different lifestyles.
This article is intended for educational and informational purposes. All nutritional figures are sourced from verified Certificate of Analysis (COA) data. Always consult your physician or registered dietitian for personalised dietary advice, particularly if you are managing a health condition.
What Does Sugar Free Actually Mean? Understanding the Label
Before choosing a snack, it pays to understand what sits behind the claim on the front of the pack. Sugar Free and No Added Sugar are two distinct, legally defined terms under UK and EU food law, and they are not interchangeable.
The Legal Definitions (UK and EU)
| Label Claim | Legal Threshold | What It Means in Practice | Diablo Usage |
|---|---|---|---|
| Sugar Free (SF) | No more than 0.5g sugars per 100g | The product contains almost no sugar. Sweeteners do all the work. Any sugars present are at trace level. | Used on qualifying products |
| No Added Sugar (NAS) | No mono- or disaccharides added during manufacturing | No sugar was added in production. Naturally occurring sugars from ingredients such as milk solids or fruit may still be present. | Used on qualifying products |
| Low Sugar | No more than 5g sugars per 100g | Sugar is reduced but not eliminated. Higher than SF or NAS. | Not used in Diablo range |
| Low Calorie | No more than 40 kcal per 100g (solid foods) | Very few food products meet this threshold. Most confectionery does not qualify. | Not applicable to confectionery |

Low calorie and sugar free are not the same thing. A product can be sugar free and still be calorie-dense, because fats and polyols both contribute calories. When looking for snacks under 100 calories, always check the per-serving energy figure alongside the sugar claim.
How Polyol Sweeteners Work
Sugar-free confectionery is sweetened using polyols, also known as sugar alcohols. The most common in the Diablo range include isomalt, maltitol, sorbitol, and maltitol syrup. These compounds provide sweetness with a lower caloric contribution than sucrose, which delivers 4 kcal per gram.
Polyols contribute approximately 2.4 kcal per gram (maltitol) to around 0.2 kcal per gram (erythritol), depending on the specific compound. They are absorbed more slowly than sugar, which is the point of using them. One authorised nutrition claim covers the glucose question, and it is worded precisely:
"Consumption of foods containing maltitol instead of sugar induces a lower blood glucose rise after their consumption compared to sugar-containing foods." That wording is set out in the GB nutrition and health claims register. It is a regulated nutrition claim, and it is quite different from any disease management claim.
The Polyol Note: What to Expect
UK and EU food law requires any product where polyols exceed 10% of total content to carry a mandatory statement on-pack: "Excessive consumption may produce laxative effects." Most Diablo products contain polyols well above the 10g per 100g threshold, so this statement appears on packs.
Polyols are absorbed slowly, which is the point. Packs over 10 percent polyols carry the note that excessive consumption may produce laxative effects, so enjoy a few pieces at a time and your gut adjusts.

How to Read a Nutrition Label When Choosing Sugar Free Snacks
The single most practical skill for any sugar-conscious snacker is knowing how to decode the back-of-pack nutrition information. Here is what to look for.
Five Things to Always Check
- The claim on the front: Is it Sugar Free (SF) or No Added Sugar (NAS)? These are different. SF means less than 0.5g sugars per 100g. NAS means no sugar was added, but naturally occurring sugars from ingredients may still be present. For the lowest possible sugar intake, choose SF products.
- Per serving, not per 100g: The per-100g column is useful for comparing products side by side. But the per-serving column tells you what is actually in the amount you are eating. Always check both.
- The polyol row: Look for "of which polyols" in the carbohydrates section. Polyols count toward total carbohydrates on the label but are metabolised differently. Understanding this helps you accurately assess total carb impact.
- The energy figure in kcal: This is the calorie count. For snacks under 100 kcal, look for this figure in the per-serving column, not per 100g.
- The laxative statement: If the pack says "excessive consumption may produce laxative effects", the product contains more than 10g polyols per 100g. This is a legal requirement for most sugar-free confectionery. It means moderate, sensible portions, as with any snack, are recommended.
Things to Watch Out For
- Misleading serving sizes: Some products display nutritional information based on an unrealistically small serving. If the stated serving is 15g but the whole pack is 75g and easy to eat in one sitting, the calorie figure on the front panel requires context.
- "Low fat" does not mean low calorie: In confectionery, low-fat products often compensate with additional sugar or polyols. Always look at the full nutritional panel rather than a single claim.
- Fibre claims: Under UK and EU regulations, a product can only claim to be a "source of fibre" if it contains at least 3g fibre per 100g, and "high in fibre" if it contains at least 6g per 100g. Check the fibre row if this matters to your dietary goals.
Every Diablo product is clearly labelled with the correct Sugar Free or No Added Sugar claim, verified nutritional information, and the mandatory sweetener and polyol statements. The product name itself indicates the claim: products labelled SF are Sugar Free; products labelled NAS are No Added Sugar. Never mixed or interchanged.
Sugar Free Snacking for Different Goals
Counting Calories
A pre-portioned 33 to 98 kcal snack, chosen deliberately rather than grabbed impulsively, fits into a 1,500 to 2,000 kcal daily plan without requiring any adjustment to main meals.
The practical approach: decide before you open the pack what your serving will be. With the Diablo gummy range, count out a 20g serving. With the sandwich cookies, take one serving (11g). With the sweets, take four or five pieces. Pre-portioning removes the risk of mindless overeating that can occur even with low-calorie products.
Keto, Net Carbs and Polyols
Keto snacking is governed by net carbs, calculated as total carbohydrates minus dietary fibre minus polyols (sugar alcohols). Because polyols are largely excluded from net carb calculations in practice, the figures below show what a serving actually contributes.
kcal
Diablo SF Gummy Bears (20g). 15.6g total carbs per serving and 0.02g sugars. Sweetened with maltitol, sorbitol and steviol glycosides.
kcal
Diablo SF Extra Dark Cocoa Cookie with Vanilla Cream (11g serving). 7.3g total carbs, 0.04g sugars, of which 1.9g are polyols.
kcal
Diablo SF Butter Sweets (per 4.1g piece). A single sweet carries 3.8g total carbs, of which 3.7g are polyols, and 0.02g sugars.
Individual tolerance to polyols varies. Some people following strict ketogenic protocols choose to count a proportion of polyols toward their net carb total. Start with smaller portions when introducing any new product and monitor your own response.
For Fitness and Active Lifestyles
The Diablo NAS muesli bar range is a portable option for pre- or post-activity snacking. Each full 30g bar is 94 to 98 kcal, carries a premix of vitamin D, folic acid and iron, and has no added sugar.
Post-workout, the priority is often protein alongside carbohydrate for muscle recovery. While the muesli bar range provides modest protein (1.8g per bar), combining a bar with a protein-rich food such as Greek yoghurt or cottage cheese addresses both macronutrient needs within a sensible calorie window.
For Everyday Sugar-Conscious Snacking
For anyone simply looking to reduce sugar intake, the key principle is substitution rather than elimination. A 44 kcal portion of sugar-free gummies or a 56 kcal portion of sugar-free sweets replaces a conventional snack that might carry 15 to 20g of added sugar in the same portion size. Over weeks and months, those substitutions add up in calorie and sugar terms.
A Practical Snacking Strategy: Four Steps
- Choose your snack category before you feel hungry. Having a Diablo product in a desk drawer or kitchen cupboard means the decision is made in advance, not under the influence of a craving. Gummies for sweet moments. Wafers for crunch. Sweets for slow satisfaction. Muesli bars for something more substantial.
- Determine your portion before you start. Count out or weigh your serving, then put the rest away. For sweets: four to five pieces. For gummies: approximately 20g. For chocolate: one COA-verified serving. For muesli bars: the full 30g bar is the serving.
- Plan when the snack happens. Mid-afternoon after lunch, or after dinner in place of a conventional dessert, are the windows most people plan a sweet snack for. Deciding the moment in advance makes the portion easier to keep to.
- Check the polyol note and stay within sensible limits. Products that carry the "excessive consumption may produce laxative effects" statement contain more than 10g polyols per 100g. Enjoy them as intended: as occasional treats and planned snacks, not in unlimited quantities.
