According to data from the World Health Organization, the number of people classified as overweight or obese has been growing in recent years, promoting the increase in the number of individuals with chronic non-communicable diseases due to the increase in body fat. Several pharmacological treatments have been developed to minimize this situation and increase the quality of life of these people. However, physical activity performed in a structured way (physical exercise) is effective for reducing body fat and its associated comorbidities. Among the exercises performed are moderate intensity training (MIT) and high intensity intervals (HIIT), the latter promoting changes in body composition similar to MIT in a shorter period of time. Thus, the aim of this integrative literature review was to search for articles that evaluated the use of HIIT on reducing body fat. The search was conducted in the SciELO and PubMed databases between january 2000 and december 2019. In all, eight articles were selected for the final sample. According to the articles evaluated, HIIT training becomes an alternative to MIT training regarding body fat reduction. Among the eight studies evaluated, six (75%) demonstrated a reduction in body fat levels and two (25%) did not show significant differences after the insertion of the HIIT. Thus, HIIT can be an alternative for MIT training with regard to the reduction of total and visceral body fat, due to shorter exercise time.
