Second Nature

Second Nature is a digital health company that helps people lose weight and keep it off by combining behavioural science, medical insight and nutrition. Its approach centres on building sustainable habits rather than calorie counting or fad diets, with personalised support from registered nutritionists throughout the process.

The company's main product is the Second Nature digital programme, a whole-person weight-loss programme that pairs one-to-one guidance with tracking tools and educational content. Eligible participants can also access optional medication-supported weight-loss treatments. The programme is reported to be clinically proven to help 9 out of 10 people lose weight and keep it off, with member losses of up to 20-25% of body weight over 12 months.

Second Nature works with the National Health Service in the United Kingdom and has been commissioned by the NHS since 2017, supporting over 300,000 NHS referrals. Technical work spans behavioural science, nutrition science, clinical weight management and the tracking and educational-content technology behind the programme.

The organisation describes itself as mission-driven, with the stated aim of changing minds about losing weight, and emphasises an evidence-based, whole-person approach and supportive, personalised care.
