User reviews

Great, easy to use and it’s already WORKING for me!!!

After a pre-diabetic blood result I opted to use Second Nature to support the changes I want to make to get back in a healthy range. First, it’s really easy and quick to use. Short check-in every day (when I can) to read or listen to solid advice backed by medical science and nutritional expertise.
With only small changes, without any whiff of awful grey, drab diets. I have a nutritionist on hand to answer any questions and get encouragement - so crucial for staying the course. You have to be open to it though, and engage.
So many of us are in the same boat and just want to be healthier but we could never do it ‘alone’.
I received a set of Bluetooth scales that automatically updates my weight. Been on Second Nature programme for 4 weeks and so far lost about a pound or two a week with literally NO effort other than to listen to advice and give it a go. Well done to the small but mighty team at Second Nature

Great educational tool

This programme of habit change was initially difficult, particularly around planning, preparing and cooking some of the meals. However, once I got into it I found it easy. I was able to adapt recipes with ingredients I had and not worry if I was missing a herb or particular ingredient.
The programme has taught me so much about different ways to look after yourself physically and mentally.
The changing of your habits is the prize, any weight loss is a bonus.
I would highly recommend this programme.

Weight loss journey

Have started eating more healthily and doing more exercise Hardly eat any bread or potatoes and feel much better for it xx

Great and holistic program

I was diagnosed as pre- diabetic 2 years ago and recommended this program by my GP. Whilst I did not follow it 100%- I actually did not wish to lose weight, although I did, so had to balance my intake of carbs a bit. However, it drastically changed my eating habits re sweet things etc, so I am now in the "green zone" as far as the pre-diabetes is concerned. No mire craving that afternoon biscuit ...Highly recommended!
