If you want protein from the cake itself, compare the amount on the pack: Marks & Spencer lists 24.8g per 100g for its Barbecue High Protein Rice Cakes, while Tesco lists 26.0g per 100g for Kallo Protein Lentil Cakes, which are lentil-based rather than conventional rice cakes. For a plain rice-cake snack, plan to get protein from a separate food: Kallo Lightly Salted lists 0.6g per cake and Tesco Lightly Salted lists 0.7g per cake. Check the portion you will eat and the current ingredients and allergen statements before deciding.
Compare both the per-100g figure and the amount in the portion you will eat. Marks & Spencer lists 24.8g protein per 100g for its Barbecue High Protein Rice Cakes; Tesco lists 26.0g per 100g and 1.8g per cake for Kallo Protein Lentil Cakes. The Kallo product is lentil-based, so it is a different choice from a conventional rice cake.
Plain cakes offer a base for a separately chosen protein food. Kallo Lightly Salted Wholegrain Rice Cakes list 0.6g protein per cake, and Tesco Lightly Salted Rice Cakes list 0.7g per cake; neither figure describes a protein-rich snack on its own.
Check the exact product and flavour rather than relying on the rice-cake category. The M&S high-protein cakes and Kallo Protein Lentil Cakes are listed as vegan and gluten free, but Tesco’s Kallo lentil-cake listing says they may contain sesame seed and soya. Kallo says its Lightly Salted rice cakes may contain milk, sesame seeds and soya.
Decide whether the cake needs to provide protein itself or will be a base for another food, then compare the portion and label details for that choice.
| Priority | What to check | Your needs |
|---|---|---|
| Protein in the portion | Read protein per 100g and per cake or serving. Tesco lists 26.0g per 100g but 1.8g per cake for Kallo Protein Lentil Cakes; the two figures answer different questions. | I want to know how much protein the number of cakes I will eat actually provides, not just whether the pack emphasises protein. |
| Cake or topping base | Check the main ingredients and protein per cake. Kallo Lightly Salted lists 0.6g per rice cake, and Tesco Lightly Salted lists 0.7g per rice cake. | If I prefer plain rice cakes, I can choose a separate protein food for the same snack or meal rather than counting on the cakes alone. |
| Ingredients and allergens | Read the current ingredients, allergen declaration and any may-contain statement for the exact flavour. Tesco lists sesame seed and soya in the precautionary wording for Kallo Protein Lentil Cakes. | A vegan or gluten-free label does not answer every allergen question I may have. I need to check the whole pack. |
| Whole nutrition panel | Compare the portion you expect to eat with the protein, energy, fat and salt shown on the pack. M&S lists 451kcal and 16.2g fat per 100g for its Barbecue High Protein Rice Cakes. | I want the protein figure in the context of the rest of this snack, rather than choosing from a front-of-pack claim alone. |
The amount varies by product. Kallo lists 0.6g protein per Lightly Salted rice cake, while Tesco lists 0.7g per Lightly Salted rice cake.
For a snack centred on protein, compare the stated serving amount. If you choose plain rice cakes, select a separate protein food for the snack or meal.
Lentil flour is the main listed ingredient in Kallo Protein Lentil Cakes. Their ingredients and eating experience should not be assumed to match those of a plain rice cake.
Check the ingredients and protein per cake if you are considering a lentil-based alternative; choose a rice-cake-format product if that distinction matters to you.
Vegan and gluten-free descriptions do not replace the rest of the allergen information. Food Standards Agency research explains that precautionary allergen labelling communicates the possibility of unintended allergen presence.
Read the ingredients and precautionary wording on the current pack, including when switching flavours or products.
A per-100g protein figure does not tell you how much is in the portion you will eat or show the rest of the nutrition panel. M&S lists 24.8g protein, 451kcal and 16.2g fat per 100g for its Barbecue High Protein Rice Cakes.
Compare the stated serving with the full panel, including energy, fat and salt, before deciding how the cakes fit into your snack.
These examples illustrate differences between specific cake-style snacks and plain rice cakes; a brand name alone does not establish a product’s ingredients or nutrition.
Barbecue High Protein Rice Cakes combine wholegrain brown rice and buckwheat with pea protein and lentil flour, according to Marks & Spencer’s product information.
Kallo has distinct lentil-cake and wholegrain rice-cake products, so check which one a nutrition figure describes.
Tesco Lightly Salted Rice Cakes are a brown-rice-and-sea-salt option for shoppers who want a plain topping base.
The researched flavoured products are choices for flavour and pack format rather than equivalents to the protein-focused cakes above.
This lentil-based cake is an option if you are considering an alternative to conventional rice cakes for a post-gym snack.

A lentil-based cake for shoppers who want the cake itself to contribute protein. It is not a conventional rice cake; check this exact pack’s protein per serving, ingredients and allergen statements rather than using figures for a differently named Kallo product.
The plain examples here provide small amounts per cake: Kallo lists 0.6g for Lightly Salted Wholegrain Rice Cakes, and Tesco lists 0.7g for Lightly Salted Rice Cakes. If protein is the point of your post-gym snack, choose another food to provide it alongside plain cakes.
The main ingredient differs. Tesco lists lentil flour as the main ingredient in Kallo Protein Lentil Cakes, with 26.0g protein per 100g and 1.8g per cake. Marks & Spencer’s Barbecue High Protein Rice Cakes contain wholegrain rice and buckwheat alongside pea protein and lentil flour, and list 24.8g protein per 100g. Compare the serving amounts as well as the ingredients.
No. Read the ingredients and any may-contain statement on the exact current pack. Tesco lists Kallo Protein Lentil Cakes as vegan and gluten free but says they may contain sesame seed and soya; the Food Standards Agency explains that precautionary wording signals possible unintended allergen presence.
