Crash diet for Japan's fat monkeys

A group of monkeys in a Japanese Park have been put on a strict diet after many of them ballooned from overeating.

About 50 Rhesus monkeys, who live in an enclosure at Ohama park in Osaka, have been steadily gaining weight for several years. Some became so fat they couldn't move around.

The primates are now on a crash diet, with their calorie intake being cut nearly sixty-percent.
