A study conducted on The Biggest Loser, a dieting programme with huge ratings on US television, showed that contestants lost huge amounts of weight through exercise and calorie counting. And yet this drastic loss caused their metabolic rates to plummet to such an extent that, six years later, their metabolisms were so slow that they were not able to eat the same calories as people of the same weight who had never been obese. Scientists call this ‘persistent metabolic adaptation’. And yet this was just one of dozens of anomalies that Segal found as he probed the science. ‘There were certain agreed facts, such as that any diet should include fat, salt, protein, fibre, vitamins and minerals,’ he says, ‘but beyond that, almost anything seemed to go.’ Another frustration emerged when he got into marathon running in his thirties and looked to see if diet could help him to improve his times.
