Introduction and Aims: The BEC (Basal Energy Cost /GEB) is the energy used by every cell in the human body for the maintenance of its operation. The Energy Expenditure with Physical Activities (GAF), added to the GEB and determine the GET. To estimate the GET physically active individuals is necessary to know the type of exercise performed, the frequency of training, duration and intensity. This study aimed to evaluate the different equations to estimate the GET, compare the results and point out the possible differences. Methods: A study carried out in two stages, the first part consists of a literature review and the second evaluated the GET two adult volunteers (one male and one female) regularly physically active. Results: We found in the literature five equations that estimate the GEB, WHO (1985), FAO / WHO / UNU (1985), Schofield (1985), Mifflin-St Jeor (1990) and Harris Benedict (1919), from these equations the calculations of GEB, GET and GAF for each volunteer were performed. Discussion: When selecting an equation to estimate the GEB and GET gender, the variables (weight, height and age), factor activity and METs are important requirements to determine the energy requirement. All equations had higher estimates for males. The method of Harris-Benedit gave an estimation of the GEB, GET and REE + MET larger than the other methods. Conclusion: It was found that there were no relevant differences between the equations, so all are suitable for use.
