Medical research is also finding genetic reasons why some people gain more weight than others.
It is such a cliche for the smug so and sos whose genetic inheritance contributes to their enviably slim figures to blame everyone elses overweight on selfish ill disciplined life styles.
No, I am not overweight, but there are members of my family, who are in their 50s, active (swimming 10 plus miles a week) plus wild swimming, whose blood pressure, and sugar levels are at levels that make doctors smile, yet despite a sensible diet are still overweight and have been since birth.
