For nearly two decades, bariatric surgeon Dr Andrew Jenkinson has treated thousands of people with obesity. In the second part of our exclusive serialisation of his new book, Why We Eat (Too Much), he debunks the myths around dieting and weight-loss.
Our old-fashioned understanding of obesity is slowly being challenged. Many scientists are realising that it is not the quantity of calories that are available in the food supply to a population that will affect obesity levels: it is the quality of the food available that causes obesity. Natural foods do not make populations fat. If a grain, oil and sugar based diet is fed to any population of people high levels of obesity occur.
