At Slimming World, we welcome anyone who’s struggling with their weight and needs guidance to make lasting changes to their lifestyle, including people who are taking weight loss medication. Our focus is on sustainable weight loss, through evidence-based, community-rooted support.
If you’re not a health professional and are looking for support while on weight loss medication, we’d love to welcome you to Slimming World.

The challenges of GLP-1s
There’s no doubt that the development of GLP-1 receptor agonists is a huge breakthrough in the treatment of obesity. However, weight loss injections aren’t a silver bullet. A recent University of Oxford study presented at the European Congress on Obesity found that people who’ve used GLP-1 medications typically regain weight more rapidly than when they’ve followed behavioural weight loss programmes. Full weight regain is expected within two years unless sustainable lifestyle changes are made.
There’s also the concern around the quality of dietary intake while people are taking the medication, and what impact poor nutritional intake will have on their long-term health.
Additionally, while they can offer clinically significant weight loss for some people, not everyone wants to take medication, and many people won’t meet the NHS eligibility criteria.
Slimming World’s approach for lasting change
In the 13,000 community groups that run each week and through our digital service, Slimming World Online, we help hundreds of thousands of people to lose weight and create healthy, lasting habits around food, activity and mindset.
Our programme is built on three core pillars:
- our healthy eating plan
a flexible, satisfying, calorie-controlled approach that supports members to eat a healthy balanced diet in line with government guidance.
- our active lifestyle programme
a framework that helps members to build their psychological and behavioural commitment to being active, until it’s an intrinsic part of their lifestyle.
- our empowering support system
grounded in the psychology of behaviour change to help members build their self-awareness, understanding and resilience.
Slimming World members don’t just lose weight. They gain a sense of personal achievement and rediscover their self-confidence and self-esteem. They influence their families to lead healthier, more active lives. There are only positive side effects – and so many of them.

Tailored support for GLP-1 users
We have a growing number of members who’ve joined us after starting to use the medication, as they understand the importance of making healthy changes alongside them – and having the right support to achieve this.
Members who are using GLP-1s are given additional guidance around:
- nutritional needs
to ensure a healthy, varied and balanced diet
- preserving lean muscle mass
by prioritising protein-rich food, within a healthy, varied diet, and starting (or continuing) muscle-strengthening exercises. To help with this, members have access to activity videos (including seated options for members who have limited mobility).
- side effects
until they subside, we guide members to have smaller, more frequent meals, drink plenty of water, and to stay active where they can, recommending that they discuss any worries with their healthcare provider.
