Is Obesity Hereditary? Yes, With Exception: Researchers
In a study of 226 families by Plymouth's Peninsula Medical School, researchers found that obese mothers were 10 times more likely to have obese daughters and for fathers and sons, there was a six-fold rise.
But in both cases children of the opposite sex were not affected.
According to the researchers, it was "highly unlikely" that genetics was playing a role in the findings, as it would be unusual for them to influence children along gender lines.
On the other hand, they attributed the link to some form of "behavioural sympathy" where daughters copied the lifestyles of their mothers, and sons copied the lifestyles of their fathers.
And, thus, experts believe that the government policy on tackling obesity should be re-thought.
To date, researchers have focussed on younger age groups in the belief that obese children become obese adults.
But the new findings indicate that obese adults led to obese children.
"It is the reverse of what we have thought and this has fundamental implications for policy," the BBC quoted study leader Professor Terry Wilkin as saying.
He added: "We should be targeting the parents and that is not something we have really done to date."
The researchers took weight and height measurements for children and parents over a three-year period.

I am an obese mother and my son is obese. definately hereditory and cross gender too!
since my other son living in the same house is lean [and active]. What my son that is obese and I share is what is called physical laziness or you could also call it reluctence to engage in sportivic activities, due to muscle pain in every atempt of physical activity.
The underlying cause is not clear. I remember myself even as an adolescent strugling to maintain weight and can report muscular difficulties even as a normal weight person. So, I would summarize that this research is in complete.
