Debating the merits of eating only once a day, Dr Marius Theron, vet and author of Secrets of the Diet Codes (published this month), faced strong opposition to his argument by Catherine Pereira, a dietetics and nutrition lecturer at UWC.
He believes humans should return to eating once a day, like animals do, to improve our overall health and well-being.
But Pereira believes there's no one diet that suits everyone and says that advice like his should be taken extremely cautiously.
You need 2000 calories a day. To make the assessment that a human can consume more than one day's worth of energy in one meal does not need a qualification. You can Google it.— Dr Marius Theron, veterinarian and author of Secrets of the Diet Codes
This is completely inappropriate for everybody, particularly infants, growing children, pregnant women and diabetics. I would not advise this as a public health recommendation you can give to everyone.— Catherine Pereira, Dietetics and Nutrition lecturer at UWC
Dr Theron will be making a lot of money from the book sales. He is promoting a diet where there are secret codes and secret information that you can find in that book ... Scientists don't have secrets about nutrition and diet.— Catherine Pereira, Dietetics and Nutrition lecturer at UWC
