He created the ZOE personalised nutrition programme that allows users to monitor their individual reaction to foods and develop a diet that works specifically for them.
The first of his guidelines was for people to try to eat a range of plants including herbs, spices, nuts and seeds. The second is to eat fermented foods little and often.
The third tip of Spector’s is to ‘eat the rainbow’ so people get their polyphenols. The fourth bit of advice is to avoid ultra-processed foods and the fifth is to fast overnight while your gut is resting.
He added: “One-size-fits-all diets have been disproven – they’ve been shown to be not valid. We’re not all robots with identical energy levels and calorie counts. The standard 2,500 calories for a man is simply a rough average. Many people will be above that 2,500 calories a day, many will be below it and it’s impossible to count calories accurately anyway.
"Personalised nutrition is a concept based on the fact that we’re all a lot more individual in our responses to food than we’ve been taught. There’s a ten to 20-fold difference to how each of us responds to identical foods in terms of sugar levels, fat levels and inflammation, so we need a more individualised approach to choosing the right balance of foods in our diet. In the past few years, we’ve had the technology to do this."
