Is it possible? Would like to know your thoughts.

ScienceDaily (2009-11-18) — Eight percent of obese people misperceived their body size, believing they did not need to lose weight or that they could afford to gain weight.

Those who misperceived their body size were less likely to exercise and see a physician than their counterparts who accurately perceived their body size.
