| I don't agree fully with saying that obesity is "socially contagious." But, I do somewhat follow their logical process here. If you are around others who eat very little at times, I think you are somewhat pressured to eat less. The same would go for eating more. Furthermore, lifestyles of friends and those around you closest tend to be the same, if your friends work out I think you are more likely to as well.
I could also see this issue leading to a debate on peer pressure and nature verses nurture.... |
