Depending on the type of fat you eat, there may be the possibility of being obese or, if not completely, being able to avoid it. This was deduced by Patricia Perez Matute from the University of Navarra in her research. This work has been awarded internationally by the medical journal Clinical Science.

According to the researcher, it seems that there is a greater chance of obesity if saturated fats are consumed, while with polyunsaturated fatty acids, derived from fish fat, decreases obesity and improves insulin resistance.

Patricia Pérez has investigated the activating effect of a fatty acid (EPA) on leptin. That has been the main discovery. This activating effect can be very interesting for the researcher, since all strategies that increase the level of leptin can be beneficial in weight loss treatments and therefore in diseases related to obesity (diabetes, arteriosclerosis, etc. ).

In addition, this paper provides information on the mechanisms involved in the regulation of the leptin gene, specifically on glucose metabolism.
