Everyone has that friend who doesn’t get fat at all, right?
The explanation for these people may have been discovered in the new research published in the scientific journal PLOS Genetics .
The study says that genetics has to do with weight and explains why, even if they eat well, some thin people do not get fat while others suffer to lose weight.
This explanation was only possible through a genetic comparison, carried out by researchers from the British universities of Cambridge and Bristol, of people with a BMI (body mass index) below 18, considered to be thin, with extremely overweight people (BMI over 30) and with the ideal weight (BMI between 19 and 25).
The different lifestyles were taken into account and, from there, they were analyzed and compared to see if they refer to the genetic data.
In overweight people, a greater number of genes linked to obesity were found .
In thin people, in addition to these genes being found in lesser quantities – which was already known – there were also some related to healthy thinness. That is, being thin can have a little help from genetics.
Despite this, one cannot isolate the other factors: behavior, food and lifestyle remain very relevant in body composition.
