Weight Loss Programmes

Noom® vs Second Nature


Weight management programs 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 isn’t a one-size-fits-all approach to choosing a lifestyle change program. It ultimately depends on what suits your individual needs and what fits into your lifestyle.

When it comes to working towards your weight goals, 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 lifestyle change programs: Noom® and Second Nature.

Noom® and Second Nature are both digital, app-based programs that focus on behaviour change and sustainable weight management.

Noom® focuses mainly on calories and diet, whereas Second Nature is a holistic program that can help you achieve your weight goals by targeting all angles, including nutrition, exercise, sleep, and behaviour.

Did you know?

In the UK, Second Nature was the first ever digital behavioural change program to be commissioned by their National Health Service (NHS) and continues to be part of their weight management and type 2 diabetes management service.

When programs 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 program to show you how costs compare. All admin fees are included in these prices.

Both programs provide you with a coach to support you throughout your lifestyle change journey. Noom® coaches can come from any health-related background, while Second Nature are coaches with expertise in nutrition.

Another option to get support with your diet would be to see a registered dietitian. Weekly face-to-face sessions with a registered dietitian can be very expensive ($70-$100 per session). We have added a column representing this to compare costs, labelled weekly registered dietitian (WRD).

Example nutrition query response

Nutrition is a major part of any lifestyle change. Therefore, it’s important to receive accurate and reliable nutrition advice surrounding nutrition. We asked each program 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?

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.”

Take home message

  • When choosing a weight management program, it’s important to consider what would fit into your lifestyle and help you achieve your goals
  • For those who find face-to-face meetings uncomfortable or inconvenient, digital programs are a better option
  • Noom® and Second Nature are both fully digital
  • Noom® has a clear guide of foods to eat or avoid, however, the focus is on reducing calories and daily weigh-ins, which might not benefit those with an unhealthy relationship with food
  • Second Nature provides you with an education of nutrition science, allowing you to make informed decisions yourself and develop a healthy relationship with food in the long-term

Hi Denise,

Thanks for your comment and interest in our programme!

We have a Menopause community in-app where you’ll be able to connect with other subscribers. The community is guided by a health coach who is there to support the group and also answer any questions that come up along the way. Communities are available in-app from week 4 of the programme, but you can message our support team if you’d like to join a community right away. You may find this article helpful.

I’m under a huge amount of family stress (supporting 4 members with current health issues) right now. Should I wait to start this program until I’m in a less stressful spot?

18 October, 2021

Hi Cheryl,

So sorry to hear what you’re going through at the moment. Sending you and your family our best wishes.

Do you have the capacity to implement nutritional and lifestyle changes at the moment? We do recommend home-cooking when possible and advise you follow our balanced plate model for your meals.

As a general description, our programme will help you build healthier lifestyle habits around the way you eat, move, and think.

The programme itself will take you through some nutritional and exercise-related lifestyle changes. You’ll be guided by a health coach, your nutrition expert who is there to support you 5 days a week along with the support of your own peer group. 

You’ll receive regular educational articles to help you and motivate you, taking you through different aspects of lifestyle change – including things like nutrition, sleep, exercise stress management, thought patterns, and behaviours. You’ll have about 5-10 minutes of reading daily with the option to listen to the learning articles rather than read them.

The programme is entirely digital and you’ll be able to check in and out of the app at your convenience – there isn’t a specific time you’ll need to be online.

If you’d like to learn more, you can take our health quiz here, or email with any questions 🙂
