Exercise Helps you to Lose Weight
Author: Cute Lourdez
Exercising after eating a small portion can reduce hunger and potentially help you lose weight according to the hormonal response, as Katarina Borer, professor of the School of Kinesiology at the University of Michigan in Ann Arbor and lead investigator of the study.
When the portions were small, people were more hungry than when portions were large. However, at the next meal, hunger rates were equally high for both categories. Exercise makes you feel less hungry and will not make you feel hungrier and eat more at the next meal, says this expert.
“The stomach or intestines know when you are full, and this has to do with the volume and energy content of foods,” said Borer. “Your body records the amount of food that goes in the mouth and stomach. Our stomach is the smart guy who knows what happens and it tells the brain”.
The researcher reduced calories by diet, and also made the subjects calories burned through exercise. The study showed that the caloric deficit as small meals causes hunger, but the reverse is also true because when we spend the calories through exercise after a meal.
But when Borer replaced those calories and nutrients intravenously subjects still did not feel full after a small meal or exercise, suggesting once again that the volume of food that actually passes the mouth and digestive system is causing hunger and satiety.
Borer results negate the widely accepted view that the hormone leptin acts as a satiety signal to control appetite and hunger hormone ghrelin notes he explains.
The current scientific opinion is that hormones and other sensors in the body in some way recorded our deficit or surplus of energy and calories, and then ghrelin indicates that our bodies need to eat during an energy deficit and leptin warns that we must stop eating in response to caloric satiety. The hormones ghrelin and leptin did record the availability of energy (deficit due to small portions and exercise, and excess due to large portions and nutrients delivered intravenously) but did not affect appetite, according to Borer.
The conclusions reached by Borer certainly does not mean you can eat a small serving of foods rich in calories, like a pizza, while dieting. What will happen is they will feel hungry sooner than if he had ingested large amounts of healthy foods and low in energy.
The added benefit of foods rich in nutrients but low in calories is a possible weight loss and generally good health, the researcher said. The abundance of vegetables and lean meats are more prudent options that pizza, he said, while equal volumes of both make us feel equally satisfied.
