Abstract

The obesity pandemic and its adverse effect on health and quality of life are well established. In younger populations, interoception and aberrant eating behaviour contribute to overconsumption and being overweight. Although the incidence of obesity is higher in older individuals, they remain under-...

Although the incidence of obesity is higher in older individuals, they remain under-researched in the obesity literature.
