The concept of childhood 'puppy fat' that disappears in teenage years is a myth, researchers say.

Children who are overweight or obese at 11 remain so through adolescence and probably into adulthood, a study in the 'British Medical Journal' found.

Experts said obesity was established earlier than previously thought and dismissing the problem as puppy fat could have serious health implications later. More than a quarter of children in the UK are overweight or obese and the proportion has trebled in the past 20 years.

Researchers from the Cancer Research UK health behaviour unit at UCL followed almost 6,000 children from age 11 to 16.

A further 7.6 per cent moved out of the overweight and obese categories into the normal range.
