D'urbano is a person.
It sounds simple, eat less and move more. This advice has been around for a long time. Despite all the efforts to lose weight, the worldwide rates of obese people keep on increasing. In the US, people were more likely to be at risk of diabetes and other chronic diseases because they were heavier in 2021. Why hasn't this approach worked?
One possibility is that we haven't tried hard enough. The challenge of maintaining a healthy diet and exercise habits is more difficult today than it was in the past because of cheap, tasty, highly processed foods.
The problem may be that the focus is on calories. In a recent paper, my colleagues and I questioned the basic assumption that taking in more calories than you burn is the primary cause of Obesity. We argue that the evidence shows that we are driven to eat because we are getting fat.
