BCAAs are said to aid weight loss and even stop the weight gain in the body. Various studies have shown the positive impact of consuming BCAA on losing body fat and body weight. However, there has also been a study that shows that consuming BCAA supplements did lead to a decrease in body fat but has simultaneously led to an increase in body weight and an increase in body mass. More studies are required to establish a relationship between consumption of BCAA and its impact on weight loss. Avoid consuming BCAA supplements specifically with the objective of losing weight. It should be used as part of a fitness regimen and as muscle mass increases body weight may increase. Rather than focusing on what the weighing machine says, take notice of how you feel and how your clothes fit. The aim should be to lose body fat and get healthier and BCAA supplements will aid you in this process.
