NHS primary care is too underfunded to be able to prevent people needing obesity treatment, according to a health expert.
Tam Fry, National Obesity Forum board member and chair for the Child Growth Foundation, claimed that the lack of funding means that NHS workers were overcome by their duties.
He commented that this leads to them not having the time to check for the early signs of obesity in children and intervene where necessary.
"Parents could be doing more if the government were actually on their side. I'm afraid I believe that the government tends to treat the parents as children," he added.
Mr Fry stated that the government should be giving parents more information so that they can look after their child to the best of their abilities.
Research released at the beginning of this year by the NHS indicated that 24 per cent of people aged 16 and were obese in 2007, compared to just 15 per cent in 1993.
