We found 108 articles, of which 19 were selected and analyzed in full for this study.RESULTS:Larger part of publications occurred in the last 6 years, the rats (n = 10) were used in the same proportion mice (n = 10). The choice of male animals (n = 18) and age greater than 21 days (n = 17) showed a major highlight. The greater than 5 week follow-up period (n = 18) was the most applied. A High Fat Diet was the most used in studies (n = 18) .CONCLUSIONS:Male rodents continue to be considered the species most used in experimental studies to induce obesity, also was found variations of age to the beginning of the experiment. For the most part are follow-up time studies along with the use of High Fat Diet.(AU)
