Second Nature exists to change minds about losing weight. Our app uses behavioural science to retrain your mind to make healthy choices automatically, so these stick in the long run. But we don’t just look at what you’re eating and how much you weigh. We also look at your sleep patterns, exercise levels, how you regulate emotions, and other habits that impact the way you might be feeling. We also pair you with a registered nutritionist who provides one-to-one advice and supports you to build new, healthier habits. Our app also has hundreds of simple, indulgent recipes as well as daily articles that explain the science of healthy living - so you feel empowered to make changes, rather than just being told what to do. Britain’s NHS recommends us because their own research suggests we’re twice as effective as other weight-loss programmes. 90% of Trustpilot reviews rate us as ‘excellent’ because 9 out of 10 people lose weight and keep it off, even after 12 months. We want to make losing weight feel easier; to make it feel second nature. Download the app and sign up today to start your journey! Second Nature uses Apple HealthKit to integrate your phone's step data to help you set goals.
