Self-control and grit: associations with weight management and healthy habits

Go to source). The study has highlighted how characteristics of "grit" (the ability to persevere toward long-term goals) and self-control are associated with better weight loss and weight maintenance in couples.

The 12-month study included a six-month intervention and then a follow-up after another six months with the 64 couples.

The researchers had participants fill out questionnaires to assess their levels of self-control and grit at the start and end of the study. They also engaged participants in a behavioral weight loss intervention to decrease calorie intake and increase physical activity.

At the end of the study, the researchers found that there was no couple effect. Couples did not start out with similar levels of self-control or grit, and, if one member of a couple improved their grit or self-control over the course of the study, their partner did not necessarily experience similar changes.

The Weight Loss Solo Act

"While couples tend to share weight management behaviors, this study found that there wasn’t any social influence between the couples when it comes to self-control or grit. Instead, these are more individual characteristics," said Tricia Leahey, director of the US-based Institute for Collaboration on Health, Intervention, and Policy (InCHIP).

However, even without specifically focusing on increasing self-control and grit, participants did generally see improvements in these characteristics during initial treatment, according to the study.

"That suggests that both constructs are malleable. Sometimes people think of self-control as something that doesn’t change. But this study goes to show that, with a behavioral weight loss program that teaches behavior change strategies, we can improve people’s self-control or goal pursuit,” Leahey said.
