Weight Loss Programmes

Noom® vs Second Nature

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.

Many people find online weight loss programmes more convenient and easier to fit into daily life. To save you tiresome research and help to answer some important questions, this guide compares two popular online weight loss programmes; Noom® and Second Nature.

Both Noom® and Second Nature focus on behaviour change and sustainable weight loss. Both programmes provide you with the same coach throughout the programme, allowing you to build a relationship with your coach.

The main difference is that Second Nature health coaches are registered dietitians or nutritionists, whereas Noom® coaches are not required to be registered with a professional body. Noom® focuses mainly on calories and diet, whereas Second Nature tackles weight loss from all angles, including nutrition, exercise, sleep, and behaviour.

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 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.

Both programmes provide the same coach throughout the whole programme that you can build a relationship with. The difference is that all Second Nature personal coaches are registered dietitians or nutritionists, rather than an individual from any health-related background (as with Noom®).

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:

Noom® Second Nature WN
Registered dietitian or nutritionist coach
The same, personal coach throughout the programme
3 months £47/month £35/month £300/month
6 months £47/month £23/month £300/month
12 months £47/month £16/month £300/month

Noom® provides discounts when you sign up to longer subscriptions, but then you are locked into a non-refundable contract.

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. 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?

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 loss programme, it is important to consider what would fit into your lifestyle and help you achieve your goals.
  • For those who find face-to-face weight loss meetings uncomfortable or inconvenient, online programmes are a better option.
  • Noom® and Second Nature are both fully online.
  • Second Nature provides a registered dietitian or nutritionist personal health coach, whereas Noom® coaches are not required to be registered with a professional body.
  • 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.
  • Customer support is very limited with Noom®, whereas Second Nature provides weekend and phone support options.
