You recently reported on the Christakis-Fowler hypothesis that obesity is
spread through social ties.
Obesity is contagious, but you don't catch it by watching your friends eat
too much. You catch it the same way you catch a cold--by inhaling or ingesting
The Potbelly Syndrome, Dr. Per Mårin and I show how chronic
infections cause obesity, type 2 diabetes, and heart disease. I have attached a
brief summary of our book.
I hope you will let your readers know that there is a more plausible
explanation for the spread of obesity.
The study we reported at foodconsumer.org reveals some
association between social contact and incidence of obesity, but does not
reveal any causal relationship, meaning that having an obese friend does not
guarantee you have a high risk of becoming obese.
I have a college friend who had quite some pounds and we had
worked in the same laboratory for three years, but I had never gained any noticeable
amount of weight!
Now, if having a friend with some excess weight may increase your odds of becoming
obese, the germ theory by Russell Farris is more cogent than what was
explained by the authors of the study we reported and news media.
It is an interesting theory and we encourage
everyone to take a look.
