Thoughts on the aetiology of obesity

In a previous blogg I pondered on the aetiology of obesity and wondered
if there was an infective element.
Interesting there is a paper in New Engl J Med 2007, 357, 370-9 which describes the social nature of obesity. Close contacts tend to be obese together. Obesity gathers in clusters. Siblings, husbands and wives but not to neighbours. Might fit with an infection.
Another thought is that obesity and snacking go together. To snack usually means to eat crisps, biscuits and other high energy foods. It is of course possible that the E number compounds in these foods may have a deleterious effect on the eaters and have an influence on intake , metabolism and storage of fat.
