The study was conducted by researchers at Florida State University College of Medicine who observed 1,900 Baltimore residents who were part of different and unrelated studies.
The researchers collected data regarding their weight and personality at the start of the studies and 10 years later and found that those who gained at least 10 percent of their body weight were likely to give in to temptation and were unable to control their cravings compared to others.
"Weight can be such an emotional issue; we thought that weight gain may lead to long-term changes in psychological functioning. If mind and body are intertwined, then if one changes the other should change too. That's what our findings suggest", lead researcher Angelina Sutin said.
