The ‘Happy Fat’ Effect: Why Men Pack on Pounds in the First Five Years of Marriage

A team of researchers from the Chinese Academy of Social Sciences found that men often let themselves go within the first five years of marriage. They tend to consume more calorie-dense foods and engage in less physical activity.

The researchers found that marriage is associated with a steady increase in men’s body mass index (BMI). Their obesity rate rises by about 2.5 percent, and after the first five years of married life men’s BMI tends to stabilize, the Daily Mail reports.

The team reported that they did not observe this trend among women.

Is this trend unique to China?

Although the study was conducted in China, the researchers say the pattern likely reflects a global problem.

As lead author Shiven Chuan noted, ‘The trend, often called “happy fat,” has been confirmed by numerous cohort studies conducted in developed Western countries.’ After marrying, men tend to visit the gym less frequently and start eating more, leading to an increase in BMI.

‘As men age, they face a significant risk of obesity, so it’s important for them not to “let themselves go” after marriage by maintaining healthy eating habits and regular exercise,’ Shiven Chuan said.

The researchers suggested that health authorities offer newlyweds guidance on healthy eating. Previous studies have shown that the more satisfied someone is with their intimate relationship, the more likely they are to struggle with obesity. A bit paradoxical, isn’t it?
