VIDEO: Fat monkeys put on diet

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 park's 24 hour opening is thought to be the main problem.

Many locals ignore the warning signs and feed them at night.

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

There are now plans to build an enclosure which prevents park users throwing in food.

And it seems an exercise program may have to be introduced too - or even cosmetic surgery.

For several monkeys a neat tummy tuck may be the only way to restore their once slim-line figures.
