Slimming World programme

Slimming World integrates three key principles to help people adopt a healthier lifestyle:

  • A warm, empowering group environment which supports members and facilitates behaviour change around eating and activity habits.
  • A satisfying eating plan to promote healthy eating patterns for life.
  • An activity management programme to help members gradually increase physical activity levels.

Our research:


Stubbs, R.J., Brogelli, D., Pallister, C., Avery, A., McConnon, A., and Lavin, J.H. (2012) Behavioural and Motivational Factors Associated with Weight Loss and Maintenance in a Commercial Weight Management Programme. The Open Obesity Journal. doi: 10.2174/18768237-01204010035 (open access)

  • This survey examined self-reported behaviour changes associated with weight loss and maintenance in a group of 292 longer-term Slimming World members.
  • Primary factors reported by participants as important in achieving their weight loss included not going hungry by satisfying appetite with low energy density food eaten ad libitum, following a flexible diet, peer-group support and tools to cope with small lapses.
  • A range of eating and activity behaviours was associated with weight loss maintenance.
  • It is important to offer consumers flexible solutions they can adapt to their individual lifestyle needs to support long term weight control.

  • This study investigated the attitudes and beliefs of health professionals, Slimming World Consultants (expert patients) and overweight and obese dieters, towards obesity.
  • Data were collected using a questionnaire from 287 health professionals, 85 expert patients and 116 dieters.
  • Health professionals, expert patients and dieters held similar models of obesity, identifying the same causes (lifestyle causes), consequences (medical consequences) and treatments (current recommended options) of obesity/overweight.
  • The concordance of beliefs between patients and treatment providers is an encouraging finding and may have important implications for public health strategies in this area.

Stubbs, J., Whybrow, S. and Lavin, J. 2010. Dietary lifestyle measures to enhance satiety and weight control. Nutrition Bulletin 35: 113-125.

  • Energy density should be the cornerstone of dietary weight reduction strategies because it allows people to develop lasting eating habits based on more satiating foods. This should be integrated with a package of dietary behaviour changes including reduced fat, energy density, sugars and salt, increased fibre, protein and water content of foods.
  • Practical approaches to weight management should be focused on a combined behavioural weight loss and maintenance strategies, including, coping strategies, relapse prevention, social & emotional support, the tools to cope with small lapses and physical activity.
  • Research shows people can navigate to a healthy weight if they can access the right tools, continuing care, guidance and social support to achieve sustainable lifestyle change and avoid relapse.

Survey of the impact of Slimming World on diet, activity and health in people accessing Slimming World resources and their families.

  • This paper investigates how the diet, activity levels and health of people accessing Slimming World has changed since either joining Slimming World or beginning to access its magazine and/or website.
  • It was found that people following Slimming World's dietary plan report: that they now make healthier food choices; that they are now being more physically active; and that 80% feel that their health has improved. Not only did health and physical activity of those accessing Slimming World improve, but also that of their partners and children.
  • The Slimming World dietary and physical activity programmes appear to beneficially impact on the diet and activity levels of those accessing the service and of their families.
