UK food labels follow EU and post-Brexit UK Food Information Regulations. Understanding them is essential for accurate keto tracking. Here is how to read every relevant element.
UK labels show total carbohydrates first, then “of which sugars” as a sub-category. Sugars are included within the total carbohydrate figure — they are not additional. For keto tracking, use the total carbohydrate figure and subtract dietary fibre (shown separately).
UK labels may list fibre separately from carbohydrates in the nutritional table or include it within the carbohydrate section with a note “of which fibre.” Always check both locations. Subtract fibre from total carbs for net carb calculation.
Nutritional information is per 100g AND per portion. Per-100g data is useful for comparing products; per-portion data tells you what you actually consume. Always check the portion size is realistic.
Ingredients are listed by weight — the first ingredient is present in the largest amount. If sugar appears in the first three ingredients, the product is likely not keto-compatible.
When in doubt, choose products with under 5g total carbs per 100g. This is a reliable keto-safe threshold for most packaged products. Pair label knowledge with cooking from our whole food keto recipes and packaged-free keto snacks.
UK food label literacy is a superpower for keto dieters. Five minutes of practice at the supermarket and you will never be misled by a label again.
