If you are following a low carb or keto diet and want a protein bar that actually fits your macros, this collection brings together bars with genuinely low carbohydrate counts, including options with low net carbs once you subtract fibre and sugar alcohols.

What to check on the label

Net carbs are calculated by subtracting fibre and sugar alcohol content from total carbohydrates. This is the number that matters for keto, not the total carb count on the front of the pack. If you are also avoiding sugar on top of keeping carbs low, the sugar free and dietary-specific protein bars collection overlaps with this one. If you are plant-based and low carb, the vegan and plant-based protein bars collection has some options that cross over. For the full range, head to the main protein bars collection.

Low carb bars for different budgets

Low carb bars tend to sit at the higher end of the price range because the ingredients that replace sugar and starch cost more. If you are buying regularly, the protein bars on sale page is worth bookmarking. Buying a box rather than individual bars usually works out cheaper per serve as well.

Frequently Asked Questions

What are net carbs and why do they matter for keto?

Net carbs are the carbohydrates that actually affect blood sugar. You calculate them by subtracting dietary fibre and sugar alcohols from the total carbohydrate count on the nutrition label. For keto, it is the net carb count that determines whether a bar fits your daily limit, not the total carb count.

How many carbs should a low carb protein bar have?

Most people following a keto or low carb diet aim for under 10g of net carbs per bar. The bars in this collection are selected with those targets in mind, but macro counts vary between products, so always check the individual product page for the exact numbers.

Are low carb protein bars suitable for diabetics?

Many people with diabetes find low carb protein bars a useful option because they have less impact on blood sugar than conventional bars. We would always recommend checking with your healthcare provider before making changes to your diet if you are managing diabetes.

Do low carb protein bars taste different to regular protein bars?

They can, yes. Bars that use erythritol or stevia sometimes have a slight cooling aftertaste compared to sugar. Bars sweetened with allulose tend to taste closer to sugar. Reading reviews on individual products is the best way to find one that works for your palate.

Can I find vegan low carb protein bars in Australia?

Yes, there is some crossover. The vegan and plant-based protein bars collection includes some options with low net carb counts. Check both collections and compare macro panels on individual product pages.
