A weight-loss program in Dubai is exchanging loss of weight in children for gold.

The program, called "Your Child in Gold," launched this month and lasts through Sept. 15. It offers two grams of gold for every two pounds a child loses. Two grams of gold is equivalent to $84 American dollars.

Dubai leaders decided on gold, rather than a more kid-friendly reward, because they believe it is a better way to get parents on board with this program.

Dubai is the largest city in the United Arab Emirates country. A survey published in BMC Public Health Journal in 2012 found that United Arab Emirates has the sixth-heaviest population in the world.
