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.

there a few minor glitches but on the whole it has helped me understand food, changing habits and much more, I am currently starting week 3 and have lost 2 kg, although there are adjustments to the meals if you are not looking to lose weight. I was referred by my GP. I cant wait to get to the sustainability part but everything i have made from their recipes has been so tasty and delicious, I have more confidence in trying out different foods as well as foods I have had to avoid in the past.

This programme really teaches lifestyle change. By implementing habits incrementally, it helps to make the changes stick. I find the daily lessons really useful. I've learned so much about food and the way it affects our bodies. I also like that there is a focus on mindfulness and eating triggers. This is by far the most holistic weight management programme I have found.
