The objective of this study was to analyze safe and effective weight loss strategies in Jiu-Jitsu athletes, considering their impact on performance and health. Rapid weight loss (RWL) is a common practice among Brazilian jiu-jitsu athletes seeking to compete in lower weight categories. It is usually achieved through caloric restriction, dehydration, and the use of thermal clothing, leading to a loss of 3% to 10% of body weight within a few days. However, these methods impair physical and mental performance, reducing strength, endurance, aerobic capacity, and focus, while causing fatigue, dizziness, and mood changes. In contrast, gradual and professionally supervised nutritional strategies have proven to be safer and more effective, helping to preserve lean mass and improve performance. It is concluded that although RWL may offer temporary competitive advantages, its negative health effects outweigh the benefits, highlighting the importance of proper nutritional planning and a multidisciplinary approach.
