I believe if her parents are fat then eventually down the line some where she will be fat too. I always look at the parents. To me that story never lies...if its in your genes and you don't do anything about it, it will eventually be you.
You may have missed my earlier posts.
If obesity is genetic, then EVERYONE has it, it would only be 5% of the population with any really odd polymorphism that would have them be obese (like ghrelin/leptin mutations).
It is our primitive fat storing genes, that once had humans survive when we lived in caves, not adapting to modern lifestyles.
It is more environmental, we live in an obsesogenic environment.
Modern life, the foods we eat, heating, transport is making us fat.
There are certain cultures that have more of a tendency to getting fat because of their cultural practices, both the USA and the UK are facing this right now.
There are aspects of genetics that are highly deterministic, but it is more of a dance, nature via nuture, the environment impacts the genes we have, and genes are expressed differently in response to various environmental conditions (including new interesting things like maternal nutrition or starvation).
Think about it, the world is fat now, there are more people who are overweight and/or obese than there are people who are starving, and this has happened within 40-50 years.
Genetic shifts do not happen that fast.
