Weight Loss Programmes

Noom® vs Slimming World®

title

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. When it comes to losing weight, some people want rigid rules and a quick fix, whereas others like more flexibility and a long-term lifestyle change.

To save you tiresome research and help to answer some important questions, this guide compares two popular weight loss programmes; Noom® and Slimming World® (SW). Noom is an online app-based programme, whereas you can choose between online and face-to-face plans with Slimming World.

Comparisons to the Second Nature programme are included. Second Nature is a 3-month online programme that helps you to lose weight and make sustainable lifestyle changes.

Pricing

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 (as of April 2022). All admin fees are included in these prices.

For basic monthly plans, Noom is the most expensive option. On the surface, Second Nature seems slightly more expensive than Slimming World. However, You also have the same coach throughout the whole Second Nature programme that you can build a relationship with, rather than an ad-hoc response from a different coach each time (Slimming World) or getting support from your group leader who is typically a past member with no nutrition training.

With Second Nature, you’ll have one-to-one private support from a registered dietitian or nutritionist. Ask questions, get advice on your meal plan, and tailor the plan to your lifestyle. Registration to a professional body requires a nationally recognised nutrition or dietetics degree. With Noom, you’ll also have a health coach. However, Noom coaches are not registered dietitians or nutritionists and instead have a Health Coach Certification offered by the ‘Noomiversity’, which has been approved by the National Board for Health and Wellness Coaches (NBHWC).

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:

SW Noom Second Nature WN
Private chat with a registered dietitian or nutritionist
The same, personal coach throughout the programme
Price £20/month £47/month $60 /span> £300/month

If you were to opt for the Slimming World face-to-face group meeting plan it would work out to be more expensive.

Example nutrition query response

Nutrition is a major part of any weight loss journey. Therefore, it is important to receive accurate and reliable nutrition advice surrounding nutrition. We asked each programme a common nutrition-related query to see how the information provided as an answer compares.

Q: Are eggs bad for your cholesterol? Should I avoid them?

Slimming World’s answer:

“I’m not trained in medical queries I’m afraid, this would be something to ask your Health Care team.”

Noom’s answer:

“No single food will stop or start weight loss. It’s all about balance! I suggest consulting with your doctor regarding specific needs (i.e. cholesterol).”

Second Nature’s answer:

“Eggs are a rich source of dietary cholesterol. It was previously thought that cholesterol-containing foods increase blood cholesterol and the risk of heart disease and strokes. However, this has not been shown to be the case as dietary cholesterol is poorly absorbed from the digestive system, and if cholesterol is absorbed, the body will produce less of it to balance out (and prevent blood cholesterol levels rising). Therefore, you do not need to be restricted unless recommended to do so from your GP/Healthcare professional. Eggs are among the most nutritious foods on the planet providing good quality protein as well as being loaded with vitamins and minerals.”

  • Noom and Second Nature are both online and app-based programmes, whereas Slimming World has an optional face-to-face meeting plan.

  • Noom is the most expensive programme on a monthly price plan basis.
  • Second Nature is the only programme where you get a registered dietitian or nutritionist personal health coach.
  • Noom and Slimming World have clear guides of foods to eat or avoid, which can be helpful for some but might not benefit those with an unhealthy relationship with food.

  • Second Nature answers nutrition queries with the most up to date science.
