A 5 year old girl in Newport was taken into care after her weight reached more than 10 stone (66.1kg).
The girl is more than three times her weight of a normal healthy child of her age. She was put into foster care in August 2012.
Thankfully, after she was put in care her weight has reduced to 49kg by August 2013.
The information was obtained by The Sunday Times in a Freedom of Information request.
Newport council said a thorough assessment of the child and family is always considered in cases like these.
Despite losing some weight, the girl’s body mass index (BMI) was still nearly double what it should be when it was measured in October.
The child is one of the heaviest five year olds recorded in the UK, the newspaper found. Girls her age typically weigh around three stone.
A spokeswoman for Newport council said the wellbeing of children and young people was of paramount importance when dealing with this type of case.
She said: “A thorough and comprehensive assessment of each child and their family that we work with is always undertaken. All factors will be considered in any decision that is taken.
“It would be inappropriate to comment further on this case in the best interests of the child.”
A Public Health Wales report published in July found more than 28% of five-year-olds in Wales are overweight, with 12.5% of children classed as obese.
Health experts said the figures were “worrying” but children still had time to adopt a healthier lifestyle.
The heights and weights of 29,400 reception age children were collected across Wales in the 2011-12 academic year as part of Public Health Wales’ first Child Measurement Programme report.
The results showed that seven out of 10 children aged four to five had a healthy weight but 28% were classed as overweight or obese.
The problem in Wales is worse than England and Scotland, the report found.
