Ward is keen to flag that the jury’s still out on whether tech directly causes health anxiety, but it’s clear that responsible use is crucial if you want to avoid getting sucked down a data hole. With that in mind, he’s put together a few healthy usage tips:

Contextualise the data

“Remember, data from health-monitoring devices are mere snapshots, not definitive indicators of overall health,” Ward says. “A single reading doesn’t paint the whole picture.”

Seek professional guidance

Don’t rely solely on raw numbers. These bits of tech work best if done in partnership with nutritional professionals (like the nutritionists at Zoe).

Embrace a holistic view

One reason tracking can be so attractive is that it gives you an immediate reward for changing your regime. Ward suggests thinking about health more holistically – working out how we feel mentally, physically and emotionally. If we’re tired, do we really need to track our glucose because our mate did it, or could we do with a bit more time in bed?

Be prepared to step back

Let’s be clear: if you’ve got a history of disordered eating then glucose monitoring isn’t for you. In fact, if you have any kind of health anxiety or are prone to checking your phone a lot, then this might be one trend to skip.

Concentrate on the things you can improve

As Chloe points out, there are loads of things you can do (for free) to improve your health that are founded in sound science. Zoe’s Tim Spector is forever banging on about the magic of eating at least 30 plants a week for your gut health; do that and you might find that you have less of an appetite for lots of sugar-spiking foods. He also stresses the importance of sleeping enough, exercising every day, drinking coffee (decaf or caffeinated) and staying hydrated. Yes, the Zoe programme is brilliant for showing you how these things make a difference, but you don’t need a standalone glucose monitor to guide you in the right direction.
