An overweight orang-utan is changing her ways after becoming the fattest primate in Britain.

For Oshine there will be no more sweets, jelly and marshmallows and instead she will be getting a healthy diet of fruit, vegetables and plenty of exercise.

The tubby orang-utan weighs in at a whopping 100kg - double her natural body weight.

Keepers at Monkey World in Dorset say they are changing her diet and putting her on fruit and vegetables - like other primates - until she loses her belly.

Oshine arrived at the rescue centre from South Africa having been kept as a pet for 13 years. Her sedentary and unnatural lifestyle meant her weight rocketed.

Although a fully-grown adult, Oshine is now living in the orang-utan creche at Monkey World that receives any captive-born babies in Europe whose mothers abandon them.

She is now receiving a more natural, healthy diet and meeting others of her own kind for the first time.

The Monkey World team are optimistic that Oshine is on the road to a more healthy life - both physically and mentally.
