We've all been there - summer is suddenly around corner and you realise a winter of overindulging has taken its toll on your beach body.

This is the position that two-year-old Jinx the seal pup has found herself in, after piling on the pounds due to a combination of health issues and a love of fish.

Fortunately staff at the Cornish Seal Sanctuary in Gweek have devised a diet and exercise plan to help kickstart her weight loss and improve her general health.

Jinx took part in her first training session this week with Natalie, head of enrichment at the sanctuary, who is leading the seal through husbandry training and physical enrichment to help manage her weight as, like with humans, there are health risks over carrying extra weight.

Jinx was rescued in April last year from Godrevy. She was dehydrated, malnourished and was displaying signs of anaemia.

When she first arrived at the sanctuary she was suffering periods of not being able to digest her food properly and stomach problems.

After an investigation by vet Paul Riley, it was found she had a condition similar to irritable bowel syndrome in humans. The vet found that steroids calmed her condition and therefore the decision was made to provide Jinx a permanent home at the sanctuary, as without treatment her condition would deteriorate and she would not be able to survive in the wild.

Jinx has been in the convalescence pool with the sanctuary's rehabilitating pups and fellow resident adult grey seals.

A sanctuary spokesperson said: "As Jinx could not start her training with pups around, she has been swimming after every fish and eating more than her fair share. In combination with her health condition, this has resulted in her weighing 85kg; a healthy two-year-old pup should weigh around 65kg."
