Fitness band claims to count calories digested by body
The world's biggest technology show is set to kick off in Las Vegas with 3,500 exhibitors trying to sell their innovations to an expected crowd of 160,000.
One of the most controversial products at the International Consumer Electronics Show is the GoBe fitness band which, it is claimed, can count the calories digested by the wearer's body.
The BBC's North America technology correspondent Richard Taylor has been talking to Healbe co-founder George Mikaberidze about his product.
