Shop-Bought Mayonnaise: The Good, the Bad and the Keto

Mayonnaise is a really useful ingredient when you’re on a keto diet. Along with cheese it’s one of those add-on foods which feel like a real treat and help to add that all important high-fat, low-carb element.

I’ve gone through the offerings from the main UK supermarkets to see which mayonnaises are the most suitable for keto dieters, and here’s what I found.

Unsurprisingly perhaps there’s a huge range between the best and worst (from 0 carb to 19g of carbs), so it shows how important it is to check the carb values on any shop-bought mayonnaise.

Here are the results of the best shop-bought keto-mayonnaises I’ve found, listed from low-carb to high.

As you can see the mayonnaises vary wildly in their carb content, so it’s always worth a look. If I’ve missed any off the list that you think are good (or terrible) please let me know in the comments below!

While I’ve tried hard to get an accurate list errors are possible so its worth double-checking the information for yourself. Sources are the UK online grocery stores for Sainsburys Asda, Tesco, Waitrose and Morrisons.
