It's really easy for people, especially men, to hit a BMI of 30 and not realise that they are obese. Especially in obesogenic societies where very many people are obese, morbidly obese or even super obese. This carries a range of health risks, most of which are helped by losing weight.
It's weird the source article doesn't mention weight, since it is caused by lack of sleep (especially in children and young people) and causes lack of sleep (in adults).

This association has been reported in all age groups—but has been particularly pronounced in children. It is believed that sleep in childhood and adolescence is particularly important for brain development and that insufficient sleep in youngsters may adversely affect the function of a region of the brain known as the hypothalamus, which regulates appetite and the expenditure of energy
