A simple way GPs can make a huge difference to obesity rates

A question for my GP colleagues: Have you been struck by how often obese mothers give birth to babies that grow to be fat toddlers?

We may think that this is genetic, or that it is due to shared environment. True, but there may be more to it than that.

It is possible that the genetic profile of the child is altered by the environment in which it develops in utero. So if its mother is under pressure from the obesogenic environment and is obese, with or without diabetes, the expression of the child’s genome can be adversely affected — a so-called epigenetic effect.
