Breathe Food Aroma Increases Weight Gain

To obtain the results of the study, researchers at the University of California, Berkeley, used gene therapy to cut off the olfactory senses of a group of obese mice.
The scientists then found that mice that do not smell anything, less weight than those who can smell. However, the research team was also surprised by the discovery that thinner mice who also can not smell, eat high-calorie foods with the same amount of rats that can smell.

In addition, a rat that can smell, weight doubled. While the olfactory rats are improved, they gain the most weight.
The research team believes that smelling food can trigger the body to store it rather than burn it.
"This report is one of the first studies that really shows if we manipulate olfactory, we can change how the brain accepts energy balance, and how the brain regulates the energy balance," said Celine Riera of Cedars-Sinai Medical Center in Los Angeles.

Researchers who are behind the study published in the journal Cell Metabolism hope this study could help those who have eating disorders problems, which include anorexia due to age, injury or Parkinson's disease.

This study can also help those who are trying to lose weight.
