In Dubai you’re literally worth your weight in gold writes Ariel Schwartz:

• Due to its oil wealth, Dubai’s citizens have become rich and fat. Half of all residents are now overweight.
• To combat obesity Dubai is offering citizens one gram of gold (worth ~$45) for every kilogram they lose in the month starting July 19^th.
• However residents of Dubai are now so rich that a mere gram of gold is unlikely to change their behaviour much.
• Moreover the UAE spends very little on public health, and so without a sustainable healthcare structure in place, such one-off policies might be ineffectual.
