Oshine the Bornean orangutan has shed an amazing 25kg (a quarter of her body weight) since she was taken to the ape rescue centre in 2010.

Oshine was rescued from a home in South Africa where she had been a pet for 12 years. When she was rescued, she weighed more than double the natural weight of a female orangutan, after being fed sweets and processed food for most of her life.

Oshine arrived at the centre unfit and unhealthy. After moving into a new home with five other orangutans, she has started eating healthily and exercising with her new friends. She has even started caring for an orphaned baby orangutan at the centre. Oshine can now climb, play and enjoy her new level of fitness. Just like humans, it is bad for apes to get too overweight, as they suffer from problems like heart disease.
