Expatriates who find themselves enjoying a little too much good food and drink in the company of their new friends might want to talk to their doctor about maintaining a healthy weight.
According to recent research conducted by Arizona State University, close groups of friends and family tend to be of a similar weight.
However, this is not really down to any shared ideas about acceptable body size and weight.
Neither does the idea that individuals could learn what a healthy weight is from their peers have a significant role to play.
In their study of 101 women and 812 of their closest family and friends, the team found that eating and exercising together could have more to do with why friends tend to gain or lose weight together.
Obesity is defined as having a body mass index (BMI) of 30 or above, while a BMI or 25 or above is deemed overweight.
