Madonna. Kylie… Zoe? No, she’s not an A-list celebrity, but the name of an app whose users are recognisable by the little yellow sticker on the top of their arms. The brainchild of Professor Tim Spector, this app was first developed to monitor Covid symptoms, then became a way to offer personalised nutrition plans.
Since it was founded two years ago, 130,000 people have used it, paying £199 for a personalised plan, with thousands on the waiting list. Indeed, jealousy was the main reaction when I told people I was “doing Zoe”. What this meant in practice was that for the next few weeks, I would wear a blood glucose monitor (the yellow sticker secures it) which would test what happens to my body after I eat, and transmit that information to an app to help me assess how my body responds to different foods.
