Abstract

Objective: to verify the effect of the dosage of protein ingested during weight loss in the maintenance of lean mass or fat-free mass, in addition to verifying the reduction of anthropometric parameters and body composition related to weight loss. Methods: This study is a literature review where searches for articles were carried out in the indexed electronic database Pubmed and SCIELO. The intervention of interest was a high-protein diet as a nutritional treatment for weight loss. After applying the eligibility criteria, five articles remained for analysis of the results. Results: About 405 adult individuals of both sexes were evaluated, in relation to the intervention time between 6 and 24 weeks. The mean age range ranged from 22.8 ± 4.8 to 47.4 ± 11.5, with all sedentary individuals being overweight or obese. Conclusion: high-protein diets are able to decrease anthropometric and body composition parameters such as: body weight, %BF, BMI and WC, in overweight or obese people, however, concomitantly reducing fat-free mass and not producing significant effects on muscle mass.
