I signed up, but then I am a bit of a sucker for a new nutrition related 'new approach'. Before I even got my test box, I had devoured everything the team including Tim Spector had published.
My results were no surprise, and not great.
A month or two before my test materials turned up, I had committed to a significant change in the kind of food I eat regularly. I was feeling really well on the new regime so was reluctant to make some of the experiments they suggested. There was no loss of information, because I had already worked out how my body responds these days (over sixty), when my days of carefree consumption of sugar far behind me.
In these circumstances there wasn't much for me to learn. It was though very reassuring to have objective evidence that my changes did indeed suit me. After an initial few days of transition, I have had no trouble maintaining my changes.
Wearing a continuous glucose monitor showed by that the things I am eating avoid the spikes which contribute to that sugar rollercoaster which makes life so miserable for me when I eat sugar and starchy food.
I did adopt their advice that the sweet spot for variety of plant material to eat each week, is thirty different kinds of plant. I found the way the app drips out information very tedious but it might suit anyone who had not already read all their research.
I now include an HbA1c test annually just to reassure myself that the results of my regime are as expected and buy & wear a glucose monitor for a fortnight annually too
So, no I didn't learn but but yes, I would recommend the programme to anyone whose pattern of food consumption could do with an overhaul like to make changes for the better without too much research effort required.
