UK fire and rescue services have responded to over 2,700 calls over the past five years to assist severely obese people.
A single incident can cost several thousand pounds and cases include people who have got stuck in the bath.
The figures were uncovered in an investigation by BBC 5 Live.
Peter Dartford, who speaks on behalf of the Chief Fire Officers Association, explained to Today presenter Justin Webb, "fire and rescue services are here to help and people find themselves in need of help for a number of reasons."
"We don't judge, we just get on and help people," he added.
"We are actively seeking to reduce demand for these services," he said, and emphasised that prevention is better and cheaper than cure.
