It is commonly assumed that you can "work up an appetite" with a vigorous workout. Turns out that this may not be completely accurate, at least in the time immediately following the exercise.
In fact, according to a recent research conducted at Brigham Young University in Utah, 45 minutes of moderate-to-vigorous exercise in the morning reduces a person’s motivation for food.
The researchers measured the neural activity of 35 women while they viewed food images, both following a morning of exercise and a morning without exercise, and found out that their attentional response to the food pictures was considerably lower after working out.
"This study provides evidence that exercise not only affects energy output, but it also may affect how people respond to food cues," professor James LeCheminant said.
What is really interesting is that the 45 minutes exercise routine not only curbed the women’s response to the food images, but also resulted in an increase in physical activity during the day, regardless of body mass index.
Also, the women in the experiment did not eat more food in the exercise day (to make up for the extra calories burned) they ate approximately the same amount of calories than in the non-exercise day.
The researchers pointed out that this is one of the first studies that looks specifically at neurologically-determined food motivation in response to exercise and that researchers still need to determine how long the diminished food motivation lasts after exercise to what extent it persist with consistent, long-term exercise.
There are many things that influence and exercise is just one of the variables that come into play.
Still, the outcomes of this study are not only interesting but seem to contradict a popular belief deeply rooted in our minds, that exercising can increase appetite.
Instead, it appears that exercising can not only curb your food craving but will put you on the right track for exercising even more.
