The research group of Dr. Beáta Lontay published their most recent findings on the mechanism of fat deposition in the journal Stem Cells Development. Obesity is a medical condition in which excess body fat accumulates to an extent that it may have a negative effect on health. Obesity is most commonly caused by excessive food intake in the form of fatty acids. While we have been led to believe that all fatty acids are "bad" for us, it became clear that short and medium chain fatty acids have health benefits.
