Previous studies have confirmed that exercising could help people manage their desire for nicotine and other drugs. It is the first time exercise is linked to food craving.
The Exeter study compared 25 regular chocolate eaters who were asked to abstain eating the sweet for three days. Then they were assigned either to walk or rest for 15 minutes, followed by involving them in tasks that would induce their craving for chocolate like opening a chocolate bar.
The study found out that those who exercised had lower cravings for chocolate compared to those who rested.
According to Professor Adrian Taylor of the university's School of Sport and Health Sciences and the lead author of the study, "Neuroscientists have suggested common processes in the reward centers of the brain between drug and food addictions and it may be that exercise effects brain chemicals that help to regulate mood and cravings. This could be good news for people who struggle to manage their cravings for sugary snacks and want to lose weight."
Prior studies said 97 percent of females and 68 percent of males experience having food cravings. On top of their list of craved food is chocolate, which contains biologically active ingredients that temporarily enhance mood. With this effect, many people develop a habit of eating chocolate, especially when they are stressed, when it is around or when not doing anything.
Taylor said, "While enjoying the occasional chocolate bar is fine, regular eating may lead to stronger cravings during stress and when it is readily available. Recognizing what causes us to eat high energy snacks, even if we have plans to not do so, can be helpful."
The study was published online in the Appetite journal.
