A man has devised a genius diet hack: sniffing the bad food but eating the good food in this hilarious moment captured in Fresno, California on August 2.

The man sniffs the chips on his plate but takes a bite out of the apple in his hand.

"I know dieting can be hard. I’m a registered nurse and take health and nutrition seriously. I wanted to create a video that could in fact inspire and help others with dieting whiles giving them a good laugh at the same time," said the filmer.
