Numan and Second Nature are weight-loss programmes offering a Wegovy weight-loss injection alongside a digital lifestyle intervention.

Ideally, we’d lose weight without needing the support of medication. However, for those individuals who’ve tried to lose weight consistently over many years without success, extra support might be needed.

If you’re looking for a weight-loss programme alongside a Wegovy weight-loss injection like semaglutide, we will be biased and recommend that you choose Second Nature over Numan.

The main difference between the two programmes is experience. Second Nature has been delivering weight-loss services in the UK for the NHS since 2017; Second Nature was the first digital weight-loss programme to be commissioned by the NHS.

Furthermore, in 2022, research published in the BMJ demonstrated that Second Nature was more than twice as effective as four other well-known weight-loss programmes in the UK.

This data is in addition to over seven years of clinical data showcasing the impact of the Second Nature programme on weight loss and type 2 diabetes. For a complete outline of our clinical data, click here.

The research behind our programme is why we continue to build on our partnership with the NHS and expand our work within the healthcare sector.

In comparison, Numan originally started as a men’s health organisation, selling supplements and pharmaceutical products specifically focused on men’s health.

Numan launched its weight-loss programme in 2022 alongside a GLP-1 medication, semaglutide. Numan doesn’t have any published or pre-print data showcasing its effectiveness.

However, there are some similarities between the two programmes, which we’ve summarised below.

The three main similarities between Numan and Second Nature

  1. Whole-food approach to weight loss: Both programmes recommend a whole-food-rich diet to support sustainable weight loss.
  2. Pharmacy partnerships: Both companies are partnered with a pharmacy to deliver the programme and ensure the clinical safety of all patients.
  3. Health coaches and nutritionists: Both programmes utilise the expertise of registered nutritionists or dietitians as health coaches to provide personalised support.

Additionally, there are several key differences between the two programmes that go beyond the level of experience that we’ve described above. These are summarised below.

The three main differences between Numan and Second Nature

1) Approach to nutrition: what does Numan believe in?

On Numan’s homepage, they advertise that their programme will help you ‘reframe your relationship with food’.

Inherently, you’d imagine their content would mirror this and promote a positive relationship with food to help you lose weight.

Interestingly, though, this doesn’t seem to be the case. Their website contains many articles on the importance of calorie counting and listing foods to ‘avoid’ when trying to lose weight.

Research shows that dieting and restrained eating practices (like avoiding specific foods or entire food groups) predict weight gain, not weight loss.

One of the reasons for this is known as the ‘white bear problem’, a theory in psychology that states that the more you try and restrict a thought (or food) from your mind, the more accessible that thought is to you.

Essentially, when you try to identify foods as bad and to be avoided, you’re more likely to think about them and overeat them.

Second Nature knows this. Our evidence-based programme uses the most up-to-date psychological, nutritional, and health science.

We don’t recommend you cut out entire food groups or say to ‘avoid’ any foods. We provide you with a sensible, flexible approach to nutrition that is healthy and sustainable so you can lose weight and keep it off in the long term.

2) Second Nature is NHS-trusted and NICE-approved

Second Nature has been trusted by the NHS since 2017. We’ve delivered programmes for the NHS in type 2 diabetes management, diabetes prevention, and weight management.

The National Institute of Health and Care Excellence (NICE) recently announced that Wegovy would be available via digital weight management services provided by Second Nature and three other companies supporting the NHS.

This approval recognises the high level of patient care and support that Second Nature has provided our members in the past.

In comparison, Numan has no affiliations with the NHS or trusted healthcare providers in the UK. (This isn’t to say they won’t continue to grow and develop these partnerships in the future.)


3) Second Nature is clinically proven

Second Nature has over seven years of published clinical data outlining its effectiveness.

Our programme is proven to support individuals to lose weight; individuals on our programme lose an average of over 6kg after 12 months.

Additionally, our programme is proven to support individuals living with type 2 diabetes to lower their blood sugar levels.

So much so that our original pilot in Portsmouth with the NHS showed that 40% of patients lowered their HbA1c (average blood sugar levels) below the diagnostic threshold for type 2 diabetes. Putting them on the path to potential remission in the future.

Additionally, Second Nature has recently published the first paper to outline the effectiveness of a digital programme alongside semaglutide medication.

You can find all of Second Nature’s published data here.

In comparison, Numan doesn’t currently have any published data in medical journals showcasing the impact of their programme on weight loss, blood sugar control, or other health markers.

However, this may change in the future as the company grows and collects more data.

Take home message

We live in a paradoxical time where we have more options than ever to help us lose weight and achieve a healthy lifestyle. At the same time, obesity and chronic disease rates worldwide continue to rise.

There’s a lot we don’t know about treating obesity and chronic disease, but we do know there won’t be a global solution for everyone.

Numan’s weight-loss programme is very new, and it’s unclear how effective it is as there’s no published data supporting its effectiveness.

In contrast, Second Nature is the market leader in sustainable weight loss and has been trusted by the NHS since 2017 to deliver weight loss services across the UK.

We’ve now helped over 250,000 people lose weight and keep it off. If you’d like to join our community, click on the button below to see if you’re eligible for our Wegovy programme.
