Although red meat is packed withprotein, a nutrient shown to help the weightloss It is also a rich source of iron. This mineral, when it is consumed in excess, can increase the risk of weight gain and illness, according to aJournal of the Clinical Survey to study.

In short: when the levels of laptin are low, we are left with amonster appetite It makes us eat too much.

In the study, the researchers divided the male mice into two groups: a group of Hautes mg / kg), while the other group was fed a low iron diet (35 mg / kg). After two months, researchers measured iron levels in adipose animal tissues. As excess iron can not be excreted, an increase of 215% iron was observed in the high iron group because levels laptine severely reduced. In turn, the food intake of these animals was also much larger.

And this translates into a crowd of negative consequences in humans: "In people, the high iron ... has been involved as a factor contributing to many diseases, including diabetes, foie gras disease and disease Alzheimer, so that's another reason for not eating a lot of red meat, "Don McClain, MD, Ph.D., the main author of the study said in a statement. "We do not yet know what optimal level in iron fabric is, but we hope to make an important clinical trial to determine if the decrease in iron levels has effects on the risk of weight and diabetes," he adds .
