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.

Second Nature uses Apple HealthKit to integrate your phone's step data to help you set goals.

Just Superb!

No gimmicks, no sugar free choc bars, but good food cooked from scratch everyday.
SN have been quite revolutionary and inspirational in helping me understand nutrition and weight loss, from emotional interactions and what I call ‘blind blockers’ to how we deal with food and our weight.
The nutritionists are great, really know their subject and how to support your journey, whether it’s weight loss or other nutritional issues. The numerous on line communities are brilliant too.
I’ve lost all the weight I wanted to loose and kept my weight stable for over 6months. Plus, and this is the GAME CHANGER!…… with their fantastic recipes and shared nutritional learning I feel I now much better understand what I eat and confident I can maintain my weight.
I’ve always cooked and liked cooking my main meals from scratch, and thought I understood a lot about food nutrition, SN helped me raise that level of understanding in a startlingly easy to apply way. Their recipes are wholesome, up to the minute and definitely family friendly, so much so that many recipes have become weekly go tos. THANK YOU SECOND NATURE! You really have changed my life! 😇

Great app!

I really like the digital scales paired with the app so I can very easily keep track of my weight loss. They paired easily with my iPhone 11. I’ve managed to lose just over 2 stone in 8 months and I’m still losing weight. I’ve learned so much more about nutrition than I knew before. I feel more confident in making the right choices. It really feels like a lifestyle change rather than a diet. The recipes are great - I enjoy them more than most of the food I was eating before! Blood test is now reading in the normal range. It just goes to show if you give the app 100% of your effort, do what it recommends even if you don’t think it will work, you will see tiny incremental changes that all add up to a big improvement.

My Second Nature Experience

I was put on this plan by the NHS as I was mildly diabetic and the next step was to go on medication. After 12 weeks my sugar levels were down to an acceptable level.
Of the various diets I’ve tried during my life I find the Second Nature plan is the easiest to follow and maintain. There are a good selection of recipes and most of the ones I’ve tried have gone down well with the rest of the family, maybe with an extra serving of carbs for them. It’s ok to have days off for special occasions or even relax it a bit for holidays and then get back to it again. It’s good to have support from others when you need it. I can’t believe how many people have told me how good I’m looking which is a real boost.
I like that you also get help with sleep, stress and positive mindset. That’s really helped me. I do my daily gratitudes most days and write a daily journal.
I haven’t really taken up the exercise part of the plan because I’m waiting for a hip replacement but I’m still usually pretty high on the steps leader board because I’m on my feet most of the time at work.
I would ( & have) recommend this plan.
