Best Low-Calorie Snacks: The Complete List

What Are Low-Calorie Snacks?

There is no single official definition of a “low-calorie snack.” As a practical guide, many people choose snacks in the range of roughly 400 to 600kJ (about 95 to 143 calories) per serve, depending on their energy needs and the role the snack plays in their day. The most satisfying low-kJ options tend to be whole foods naturally high in water, fibre or protein rather than engineered diet products with reduced fat and added sugar.

Low-calorie snacks have a reputation problem. Most people picture rice cakes, plain celery, and flavourless food that makes you feel virtuous for five minutes before you’re raiding the biscuit tin. That reputation is earned by diet-culture thinking that confused low-kilojoule with low-satisfaction.

Research Finding: In an internal editorial review, The AminoHub compared nutrition panels from 150 snack products available across Coles, Woolworths and IGA in 2026. Among products marketed in the “diet,” “light” or “97% fat-free” categories, 71% listed more added sugar per 100g than the standard version of a comparable product.

What Counts as a Low-Calorie Snack?

In Australia, food energy is measured in kilojoules (kJ), and one calorie equals roughly 4.18 kilojoules. Food Standards Australia New Zealand regulates the nutrition content claims that appear on packaging, including claims such as “low energy.” The 400 to 600kJ range used throughout this guide is an editorial comparison threshold for choosing a snack. It is not a statement that any product meets the regulated criteria for a “low energy” claim.

That range sits deliberately at the upper end of common guidance. Some Australian health services use around 420kJ (roughly 100 calories) as a practical snack ceiling, which works well for a light between-meals snack. This guide allows up to 600kJ because a snack carrying real protein, such as a tub of Greek yoghurt or a tin of tuna, will usually cross 420kJ while still being the more filling choice. The best low-calorie snacks share three traits: high volume relative to energy, protein or fibre to support satiety, and whole food sources rather than processed alternatives.

Key Takeaways

✔ Under 600kJ per serve is the working benchmark used in this guide, not an official definition

✔ Protein + fibre combination = maximum satiety per kilojoule

✔ High water content = high volume, low energy

✔ “Low-fat” processed products often compensate with added sugar

Low Energy Does Not Automatically Mean Nutritious

This is the single most common mistake people make with low-calorie snacking. A packet of lollies and a tub of plain yoghurt can sit within a few kilojoules of each other, and nobody would argue they are equivalent. Kilojoules describe energy, not nutrition.

The Australian Dietary Guidelines recommend building your diet around a variety of foods from the five food groups, while limiting foods high in saturated fat, added salt and added sugars. A low-kilojoule snack that comes from those food groups, such as fruit, vegetables, yoghurt, legumes or fish, does two jobs at once. A low-kilojoule snack built from refined starch and sweeteners only does one.

So rather than asking only how many kilojoules a snack contains, run it through five questions: energy per serve, nutrient density, protein, fibre, and how realistic the serving size actually is. Every recommendation in this guide is chosen on that basis, not on kilojoules alone.

Best Low-Calorie Snacks at a Glance

If you only want one recommendation, start here. The full tables below give the detail.

Complete Low-Calorie Snack List

Nutrition values below are approximate and vary by brand, serving size and preparation. Figures are drawn from manufacturer nutrition information panels where a specific product is named, and from standard Australian food composition data for generic whole foods. Check the product label for current information. Where a product is listed as containing no added sugar, this refers to plain, unsweetened varieties. Flavoured versions of the same product often differ significantly.

Under 200kJ (Under ~50 Calories)

200–400kJ Range (~50–95 Calories)

How we score snacks: The AminoHub Score is built from five equally weighted criteria, each worth 20 points: protein density, dietary fibre, added sugar, sodium, and ingredient quality. It is an editorial comparison tool used across our snack guides, not a clinical or medical rating, and it is not eligible for regulated nutrition claims. A lower score doesn’t mean a food should be avoided. It means the snack is doing something other than delivering protein and fibre.

Low-Calorie vs Low-Energy-Density Snacks

These two ideas often get treated as the same thing, but they aren’t. A snack can be low in kilojoules simply because the serving is small, or it can be genuinely filling because it has low energy density — fewer kilojoules spread across a larger volume of food.

Ten almonds are low in kilojoules for that portion, but they’re energy dense, so the serving is small and disappears quickly. Cucumber is the opposite: very low energy density, high water content, and you can eat a lot of it. Greek yoghurt sits somewhere else again — moderate energy density, but the protein does the satiety work rather than the volume.

This matters when choosing a snack. If you want to feel physically full, prioritise high-volume, low-energy-density foods. If you want to stay full for longer between meals, prioritise protein. Combining both, such as vegetables with hummus or yoghurt with berries, generally works better than either alone.

Per Serve vs Per 100g: How to Read the Panel

Every Australian nutrition information panel gives you two columns, and confusing them is the fastest way to misjudge a snack. The per serve column uses whatever serving size the manufacturer decided on, which may be far smaller than what you would actually eat. The per 100g column is the only one that lets you compare two products fairly.

A muesli bar showing 480kJ per serve looks reasonable until you notice the serve is half a bar. Compare the same product per 100g against a tub of yoghurt and the gap becomes obvious. Use per 100g to compare products, then use per serve to work out what you will actually eat.

Also worth checking: Two things get overlooked in low-calorie snacking. Sodium is one: tinned fish, hummus, cottage cheese, miso and packaged savoury snacks can carry meaningful salt loads even when the kilojoules are modest. Allergens are the other: several snacks in this guide contain nuts, dairy, soy or fish, so check labels if that applies to you or anyone you are feeding.

Greek Yoghurt vs Flavoured “97% Fat Free” Yoghurt

Nutrition Tip

Removing fat from a processed snack often means sugar or refined starch is added to maintain taste and texture, though this isn’t true of every product. Read the protein and added sugar columns on the nutrition panel, not just total fat.

Zero and Near-Zero Calorie Options

• Herbal tea (peppermint, chamomile) — ~10kJ
• Sparkling water with lemon — 0kJ
• Miso soup (1 sachet) — ~100kJ; warm savoury satisfaction
• Black coffee — ~15kJ

Low-Calorie Snacks by Situation

Different needs pull you toward different snacks. Each of these has a dedicated guide that goes deeper than this page does.

If you want the highest protein per kilojoule

Tinned tuna in spring water, plain Greek yoghurt, cottage cheese and edamame lead this category. Protein is what carries you to the next meal rather than the next hour.

If you want the greatest fullness for the fewest kilojoules

Volume does the work here. Air-popped popcorn, raw vegetables with a legume-based dip, and water-rich fruit fill more space for less energy.

If you need to stay under 100 calories

Almost everything in the under-200kJ table qualifies, along with a single hard-boiled egg, ten almonds or a small tub of yoghurt at the lower end of the 200 to 400kJ band.

If you are shopping rather than preparing

Stick to the perimeter categories: plain yoghurt, tinned fish, wholegrain crackers, legume dips and seasonal fruit. The supermarket table above covers what to compare in each.

Research Snapshot

• Only 18% of 150 Australian supermarket snacks reviewed deliver ≥10g protein AND ≤5g added sugar per serve (AminoHub Internal Review, 2026)
• 71% of “diet” or “light” category products contained more added sugar per 100g than full-fat versions
• Some research suggests higher-protein snacks may improve fullness for some people, though the effect depends on the food, portion size and individual dietary need

How We Reviewed These Products

Methodology: The AminoHub compared nutrition panels from 150 snack products available through Coles, Woolworths and IGA during 2026. Products were categorised based on their front-of-pack marketing claims and compared per 100g where appropriate, using each product’s own listed serving size.

Scope and limitations: This was an editorial comparison, not a clinical study. It was not peer reviewed and is not nationally representative. Product formulations and ranges change over time, so individual figures should be treated as indicative rather than current for any specific product.

The Bottom Line

The best low-calorie snacks are whole foods that are naturally filling: Greek yoghurt, eggs, raw vegetables, fresh fruit, tinned fish, edamame, cottage cheese, and air-popped popcorn.
