dos S. Rodrigues AM, et al. – This paper dealt with the investigation of the best predictive equations for estimating resting energy expenditure (REE), in overweight and obese women with polycystic ovary syndrome (PCOS). IT was determined that World Health Organization/Food and Agriculture Organization of the United Nations/United Nations University weight (WHO/FAO/UNU weight) could calculate the REE in overweight and obese women with PCOS. Nevertheless, the low individual accuracy and agreement in association with measured REE (mREE) indicated caution, in terms of when to use the formula to perform an individualized nutritional plan.
