Weight loss programmes can provide a helpful structure for your health journey when you feel out of control with unhealthy habits. They can also be a great way to join individuals going on the same journey, which can be incredibly motivating.

Everyone is different, and there is not a one-size-fits-all approach to choosing a weight loss programme. It ultimately depends on what suits your individual needs and what fits into your lifestyle. Some people want rigid rules and a quick fix, whereas others like more flexibility and a long-term lifestyle change.

This guide compares two of the most popular weight loss programmes; Weight Watchers® (WW) and Slimming World® (SW). Comparisons to the OurPath programme are included. OurPath is a 3-month online programme that helps you to lose weight and make sustainable lifestyle changes.

We spoke to two OurPath members, who have all previously tried Weight Watchers® and Slimming World®, to get an idea of how they compare from the point of view of a user.

When programmes provide price plans in different formats, it can be hard to accurately compare prices. To make this easier, we have calculated the price of monthly digital basic price plans on each programme to show you how costs compare over 3, 6, and 12 months (as of June 2019). All admin fees are included in these prices.

Weight Watchers® is marginally cheaper than Slimming World®, and they provide a similar service in terms of support and programme features. On the surface, OurPath seems slightly more expensive, however, your personal coach is a registered dietitian or nutritionist, rather than a previous member or customer service representative. You also have the same coach throughout the whole OurPath programme that you can build a relationship with, rather than an ad-hoc response from a different coach each time (Weight Watchers® and Slimming World®).

Registration to a professional body requires a nationally recognised nutrition or dietetics degree. Weekly face-to-face sessions with a registered dietitian or nutritionist can be very expensive (£40-£100/hour). We have added a column representing this to compare costs (Weekly Nutritionist – WN).

Monthly (basic) digital subscriptions:

WW SW OurPath WN
Registered dietitian or nutritionist coach
The same, personal coach throughout the programme
3 months £16/month £20/month £30/month £300/month
6 months £15/month £20/month £20/month £300/month
12 months £14/month £20/month £15/month £300/month

If you were to opt for the Weight Watchers® or Slimming World® face-to-face group meeting plans it would work out to be more expensive.

Meet the members

Profile cards for three different women, showing name, age and occupation.

What motivated you to lose weight?

Icon of a woman.“I felt unhealthy and older than my years physically. I was worried about developing diabetes and many other health problems, such as female cancers. Every so often I would try some form of weight loss plan, but I was going round in circles.”

Icon of a woman.“Putting on weight since the menopause.”

Did you have fears about losing weight?

Icon of a woman.“That losing weight would mean a joyless existence of counting and measuring everything I ate. [I did not think] that losing weight could equate to enjoying meals or my food in the same way [but rather] would be a life of endless grumpy hunger!”

Icon of a woman.“That I would not be able to lose weight as I had a thyroid problem.”

How convenient was each programme?

Weight Watchers®:

Icon of a woman.“The app was convenient, but the need to count and measure everything was quite oppressive! Following Weight Watchers® did take up a lot of waking thought (constantly working out what I could get with my allowance !)”

Icon of a woman.“The weekly meetings were not convenient.”

Slimming World®:

Icon of a woman.“Still a fair bit of counting and measuring, but not as much as Weight Watchers®. I still felt that Slimming World® took up a lot of waking thought.”

Icon of a woman.“These weekly meetings were also not convenient.”


Icon of a woman.“Wasn’t too bad to fit into daily life. I spend less time measuring and counting things but do seem to spend more time planning and cooking meals. I think it takes a bit longer to get used to the guidelines, but I don’t feel OurPath is as rigid or takes over my waking thoughts as much as the other clubs did. Knowing I can have a nice and satisfying main meal stops me obsessing about food in between meals.”

Icon of a woman.“I love that OurPath is online, which makes it very convenient.”

What support was available?

Weight Watchers®:

Icon of a woman.“Online diary, recipes, and message boards/chat facilities, plus classes (which I didn’t enjoy as I am not a sociable participant in weight loss clubs!). The magazines (which I bought separately) were a good source of info and ideas that I could read privately. I never accessed any online advice”

Icon of a woman.“Mainly at the weekly meeting. Plus a guide book.”

Slimming World®:

Icon of a woman.“Online resources felt less developed than Weight Watchers® (although this was a while ago). Classes and magazines were the main support (again preferred magazines).”

Icon of a woman.“Also mainly at the weekly meeting. Plus I was given a guide book.”


Icon of a woman.“The app with recipes plus access to a health coach mentor (either through the chat facility or privately). The small groups of starters and the chat facility was also a support.”

Icon of a woman.“There is mentor support, support from peers, and support through the daily articles, which is all available online.”

What were the main challenges?

Weight Watchers®:

Icon of a woman.“I felt hungry and deprived whilst doing it and did not feel like a way of eating that I would want to sustain long term. I also hated the group meetings.”

Icon of a woman.“Getting to the meetings and counting points.”

Slimming World®:

Icon of a woman.“I also felt hungry and deprived whilst doing it. The online resources were not as extensive as Weight Watchers®. I also hated the group meetings.”

Icon of a woman.“Working out their system and getting to the meetings was challenging.”


Icon of a woman.“Initially represented quite a major change in eating and cooking style and felt so wrong to use full-fat products but surprisingly it was quite easy to get used to and does feel like a way of eating that I could happily continue in the long term. The 12-week programme covered quite a lot of ground, which takes time to consolidate and learn.”

Icon of a woman.“Probably trying to achieve the exercise goals I have been set.”

What was your favourite aspect?

Weight Watchers®:

Icon of a woman.“That you could opt for an online-only programme and the online resources were good.”

Icon of a woman.“Probably occasionally going to the meetings with a friend.”

Slimming World®:

Icon of a woman.“That you could eat certain foods quite freely.”

Icon of a woman.“Also going to the meeting with a friend.”


Icon of a woman.“The basic principles were easy to remember. I liked that OurPath looked at all aspects of health and was a more forgiving but long-term approach. The focus was not just on weight loss but how you feel and your well-being. The basic principles were easy to remember. That it is run online and you can get as involved as much or as little as you like.”

Icon of a woman.“I love that I have really learnt so much, which I did not on the other programmes. I feel l now have a real understanding of nutrition science.”

Which was the best value for money?

Icon of a woman.“I would have to say that OurPath has been the best value for money and the ability to drop out and get a refund within the first few weeks was comforting – a no risk trial!”

Icon of a woman.“As I did not stay on either Weight Watchers® or Slimming World® for long, I cannot say they were good value. There is slightly more cost with OurPath, but the amount of support and quality information makes it much better value for money as the outcomes are far superior.”

Did you lose weight and keep it off?

Weight Watchers®:

Icon of a woman.“Yes I lost a bit but did not keep it off.”

Icon of a woman.“I lost a little but put it back on very quickly.”

Slimming World®:

Icon of a woman.“Yes I lost a bit but did not keep it off.”

Icon of a woman.“I lost a little bit did not keep it off.”


Icon of a woman.“I have lost almost a stone and a half in the last 12 weeks. I hope to keep it off as I will not be changing the way I eat. I am confident that I will lose some more!”

Icon of a woman.“I am still on the program and have lost weight and feel that OurPath is sustainable. My mindset has changed my motivation has improved, so I am confident that I will not put the weight that I have lost back on.”

Take home message

  • When choosing a weight loss programme, it is important to consider your goals and what would fit into your lifestyle.
  • Everyone is different and there is not a one-size-fits-all approach to weight loss.
  • Some people prefer having more rigid rules to follow, as with Weight Watchers® and Slimming World®, but others find it confusing.
  • Weight Watchers® and Slimming World® seem to focus on diet, whereas OurPath tackles weight loss from all angles (exercise, nutrition, sleep, mindset).
  • OurPath members seem confident that they have been given the tools to stay on track with their healthy habits in the long term, not just during the programme.
  • Face-to-face meetings (provided by Weight Watchers® and Slimming World®) work for some people more than others, depending on how you’re motivated.
  • OurPath is totally online and app-based, which makes it easier to fit into daily life for some people.

I’m following OurPath basic programme and find it inspirational. It’s giving me the insight that I’ve lacked when I’ve followed weight loss plans before. I’ve used both WW and SW successfully in the past but my problem has been finding continued motivation when the going gets tough.
Thanks to OurPath I’m feeling full of energy, loosing weight, eating and sleeping well using the tools and techniques I’ve learnt from the app’s Toolbox. Its a great resource for the future. Thank you.

I would like to sign up for a month. If the program works I will continue. Can you give me a quote for 1 month.

Hi Claire, thank you for your comment! Unfortunately, we do not offer the programme for 1 month, the full core programme lasts for 3 months. We do, however, offer a 2-week risk-free trial period where you can cancel at any point in the first 2-weeks and receive a full refund if you decide the programme isn’t right for you. To find out more, take our health quiz here.

I am a member of Sliiming World. and in 6 weeks have lost 1st 2.5lbs. As someone who is nearly 70 and has always struggled with weight I find that pretty amazing. I have never felt hungry on the plan and the weighing and measuring are minimal. Love the meetings though am not really a fan of all girl { and apart from a couple of guys) groups. Love the awards system and the fact that I can text my consultant and get a quick response to any queries. The website is great; I can record my food intake, my weight loss, my exercise and my awards. The food optimising system isn’t rocket science and I like the fact that I can eat ‘free’ foods at any time and as much as I like. I feel this is an eating plan I will be able to follow for the rest of my life and I can easily vary meals to cater for my (tall, slim, younger) husband.
On of my main reasons for wishing to lose weight is that I was diagnosed as being in danger of developing diabetes. My health adviser has approved Slimming World as a way to lose weight and reduce blood sugar.
