About this app

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.

I've always loved the app for its attitude towards balanced eating and understanding nutrition. I find the recent adoption of weight loss medication highly off-brand and inappropriate. They email about it a lot which is triggering for someone trying to find balance instead of disorder. It also simply doesn't practice what they preach, it feels like a sellout. Also, the app has been pretty glitchy recently.

The information provided is clearly stated and very well supported by research and if you need more support it's just a click away. I find the recipe section helpful ☺️ it has many options and has given me some different alternatives to meals and idea's I hadn't thought about. Thank you 😊

I feel more confident in how to avoid becoming diabetic and there's lots of support and information if you're not sure of something. I have a better understanding about what nutrition is healthy and I find the recipes are not very restrictive and are tailored to people's different lifestyles. I would highly recommend this programme.
