Tokyo: Restricting access to food can increase hormone levels, which can also boost your exercise motivation, a new study has said.
A study published in the Journal of Endocrinology suggested that a jump in the levels of the appetite-stimulating hormone, ghrelin, after a period of fasting prompts mice to start voluntary exercise.
These new findings suggest that better diet control, such as limiting food intake to eating or periodic fasting, could help overweight people maintain a more effective workout routine, lose weight, and avoid disabling complications such as diabetes and heart disease.
"Our findings suggest that hunger that promotes ghrelin production may also be involved in increasing the motivation for voluntary exercise when nutrition is restricted," says author Yuji Tajiri of Kurume University in Japan.
, maintaining a healthy diet with r Eatable eating or fasting times could also promote the motivation to exercise in overweight people, "says Tajiri.
Ghrelin, often called" hunger hormone, "stimulates appetite by acting on schemes [1
studies suggest a link between ghrelin and exercise, it was unknown whether hormone levels had a direct effect on exercise motivation.
In this study, the research team examined the relationship between exercise and hormonal levels in mice.
Food intake and wheel activity were compared in mice receiving free food access to those fed only twice daily for a limited time.
Although both groups eat similar amounts of food, restricted mice consume significantly more.
Mice genetically as modified to lack ghrelin, and the restricted diet moves less than free-access mice, but this can be reversed by hormone administration.
In addition, mice are given free access to food and given ghrelin.
These findings suggest that ghrelin can play an important role in motivation for both eating and exercise in response to restricted nutrition plans.
