Many people find that attending a group programme suits them as it provides regular support as well as practical information. The three most popular ones in the UK are: Weight Watchers, Rosemary Conley Diet and Fitness Clubs, and Slimming World. There is very limited published research about the long-term effectiveness of slimming clubs, which is a pity, and hopefully more will come. But what there is suggests that the responsible clubs can be useful. Before joining any club we encourage you to find out what it offers and ask yourself what you see as the benefits for you. Most importantly, see if it offers some form of ongoing support to help you maintain your weight loss.
