"At what point do you make a law about what people can eat and what they cannot," Ayoob said. " Focusing only on diet would be a huge mistake. ...Type 2 diabetes is often a function of lifestyle.
"The good news is that shift work does not doom you to an unhealthy lifestyle, but it does mean that there needs to be some level of self-motivation for it to happen. It would be a mistake to expect the responsibility to be solely on the employers."
