I signed up last October for a year, so have just come to the end. I have mixed feelings about it. I'm not 100% convinced about the personalised testing.
When I wore the glucose monitor I didn't get big spikes or troughs with any of the tests, my lines were much steadier than that of my friend who did it at the same time, but my blood sugar response was deemed Bad (17) whilst hers was deemed Good (56). I had however reported in the submitted info that 9 months previously I'd had a HbA1c test just into the pre-diabetic range, which I had already reversed by losing 5kg and doing 10k steps a day over three months, and I now have an annually tested HbA1c which is comfortably in the healthy range. I also purchased a second glucose meter about 6 months in, which again told me I was not getting big spikes/troughs. So it's hard not to feel that this data was ignored and the reporting of a previous pre-diabetic reading just got me an automatic Bad score.
Similarly, I have genetic high cholesterol and have been on a low dose of statins for years. My cholesterol is tested every year, it's in the good range with a great ratio of good/bad, and my triglycerides are very low. Zoe deemed my fat response Poor (41). Could be correct - but would I have got the same assessment if I'd not self-reported and only provided the data from the blood test? Don't know.
My microbiome score was initially Good (53) which I was pleased about. However, all the microbiome scores have now been recalibrated using a larger dataset, and the identification of more microbes etc. My recalibrated score plummeted from a Good 53 to 39, into the Poor category. I did also get a recent (free) gut retest, which was presented as super positive because my score had increased from 39 to 42, still in the poor category. My gut-boosters list has been updated! I already eat everything on that list frequently. My gut suppressors list has been updated! There are only two things on there that I ever eat (infrequently). Sigh.
This really isn't a weight-loss tool for anyone who is actually fat rather than just a few kg over where they would like to be. This is mainly because the only way to get a decent score or to make the endless pulses palatable is to add olive oil or nuts and seeds to everything. Delicious, healthy, very calorie dense. In any case, in one of Tim Spector's recent podcasts he flatly stated that anyone who is actually obese needs surgery or ozempic/wegovy. It's clear he is a naturally lean person, who doesn't really compute that some people may overeat even if they are eating unprocessed healthy foods, because it wouldn't occur to him to do so.
I am one of those apparently irredeemable obese people. In 6 months of strict Zoe compliance alongside weights/resistance training I lost 4kg. Big whoop. In the six months since, when I stopped tracking on Zoe and instead have tracked on Nutracheck to keep an eye on protein and fibre in particular and calories in general I have lost 12kg, and have improved my muscle/fat ratios significantly as well.
Sorry, this turned into a bit of an essay! But hope it will be useful to someone. I do find the Zoe podcasts interesting enough when I'm doing my 10k steps everyday, but I won't miss the glitchy app or the guilt from the doomladen scores it gave me for any animal protein, anything approaching a carb even things like dark rye pumpernickel or more than a thimble of sherry once a year at Christmas...
