Many people have the feeling that physical exercise causes appetite. A study by the Imperial College of London and the University of Surrey, in 2007, revealed that training after meals manages to shoot the hormones that suppress hunger. That is why active people have less appetite after exercising, and even the effects may last until the next meal.
Here are more details about whether exercising causes hunger or not.
Those who develop a sports activity usually burn, on average, about 492 calories, compared to 197 of those who lead a more sedentary life. After exercising, those who made a physical effort usually eat more amount compared to those who did nothing, 913 against 762. When considering the amount of energy burned, it was found that athletes would consume fewer calories, 412 versus 565.
In this investigation, it was detected that the levels of the hormones PYY, GLP-1, and PP, which are responsible for informing the brain when the stomach is full, immediately increase as soon as the exercise is performed. These data were also confirmed with the opinion of the participants in the study, who detailed that they felt less hungry during that period.
In the past, there was some concern about the consequences that sport could have when feeding. After exercising, people usually eat a greater amount of food, and that could cancel any effect in reducing kilos. However, more recent research shows that sports activity alters people’s appetites, helping them not gain more weight.
Although it seems the opposite, it must be said that physical exercise fails to increase people’s hunger, and sometimes reduces it. With training, hormones that increase the feeling of well-being and calm the desire to eat.
Recently, the work of researchers from The University of Western Australia has also been known, where they compared the relationship between the exercise done mildly and intensely with appetite. The conclusions were published in The International Journal of Obesity and showed that people who perform a smoother activity tend to eat more than those who exercise more intensely.
Those who trained at a higher rate had lower levels of the hormone ghrelin, which is responsible for stimulating the desire to eat, also showing higher blood sugar levels. All this helps to reduce the desire to eat.
If you think that sports activity makes you hungry, it is best that before training you consume pasta, brown rice or whole-wheat bread. The important thing is that you avoid overeating and also do not take refuge in the industrial bakery, which is loaded with calories and does not give you anything from the nutritional point of view.
