An obese monkey nicknamed 'Uncle Fat' was placed on a diet after gorging on junk foodby Circa News

A morbidly obese wild monkey who gorged himself on junk food and soda left behind by tourists has been rescued and placed on a strict diet of lean protein, fruits and vegetables.

Wildlife officials caught the chunky monkey nicknamed "Uncle Fat" by locals after photos of the animal started circulating on social media last month.

Wild monkeys roam free in many parts of Thailand, attracting tourists who feed and play with the animals.

"It was not easy to catch him," said Kacha Phukem, the wildlife official who conducted the capture and rescue on April 27.

"He was the leader of his pack, and when I tried to go in, I had to fight off a flock of them with sticks."

Uncle Fat weighs three times the size of most macaques. He is believed to be believed to be between 10 and 15 years old.

To help him lose weight, his new diet is limited to 400 grams worth of lean protein, fruits and vegetables twice a day. Supakarn Kaewchot, a veterinarian in charge of Fat's diet, said she hopes to release him in a few months.

She said Uncle Fat is an example of why people shouldn’t feed wild monkeys unhealthy food.
