Boost your commitment

Two of the most important ingredients in a successful slimming campaign are commitment and motivation. Research shows that people who attend a support group and commit to attending the group each week lose weight far more effectively than those who take a more casual approach. That’s why Slimming World developed a unique system of 6 and 12-week ‘Countdown’ courses, which, as a member, you can benefit from at any time of the year.

A six or twelve week Countdown course* can boost your commitment and motivation - it's a really powerful way to give your slimming plan a boost.

Countdown courses:

  • Give your motivation a boost and help you commit more strongly to your slimming campaign – especially during difficult times such as holidays and Christmas.  
  • Help your weight loss success continue as you attend group each week for support and inspiration.
  • Offer excellent financial savings!

I stay to my group every week because I enjoy the encouragement and company of all the new friends I've made. I'm healthier, enjoying life - and being successful has given me more confidence.

a great saving

Ask your Consultant about Countdown courses this week and save up to £9.90 (€18 in Republic of Ireland)!

  • 6 week Countdown – 6 weeks for the price of 5 – get one week free!
  • 12 week Countdown – 12 weeks for the price of 10 – a tremendous two weeks free!

*Because a Countdown course has been especially created to boost your commitment and to help you strongly commit to your slimming campaign, there are a few simple rules and recommendations we ask our Consultants to let you know about. Countdowns are non-extendable and non-refundable. That’s why we ask that any holidays are booked up-front on the week you make that Countdown commitment. If you’re a shift worker, unless you’re able to attend a group (any group) each week, we’d recommend you don’t buy a Countdown. Our Countdown rules are available in group and in our club rules, which you’ll have an opportunity to read before you decide to join.

Gift vouchers

One of the most thoughtful ways of showing you care!

Slimming World gift vouchers are a wonderful way to support a friend or family member on their weight loss journey.

If someone you care about has told you they want to lose weight, help them make a start with a gift of Slimming World membership and 6 or 12 weeks attendance. If they are already a member, give them a boost with a gift of 6 or 12 free weeks (much more thoughtful than a box of chocolates!).

Please note: If you already attend a Slimming World group, you can purchase gift vouchers from your Consultant, and avoid paying P&P charges.
