If you've got a niggling question then we have a huge help section where you'll find all kinds of common questions and answers. It's split into different topics like ‘Food Optimising', ‘Exercise ’ activity' and ‘Group membership’ for you to quickly find an answer. Best of all, if you start typing your question into the search box, the clever little gizmo will predict your query and give you a drop down list of options.

If you can't see the answer you're looking for or you'd like to know whether Slimming World is for you – the very best person to speak to is your local group Consultant, who'll be able to answer any questions you have. You'll find their phone number next to the group listings in our nearest group search.
