Extreme dieting poses risks for athletic performance by depriving the body of essential nutrients needed for optimal function. Such diets can lead to muscle breakdown, decreased energy levels, weakened immune response, and increased injury susceptibility. Athletes may experience diminished performance, lack of endurance, and impaired recovery due to inadequate nutrient intake. Additionally, extreme dieting can result in mental health issues such as anxiety and disordered eating patterns. Prioritizing balanced nutrition is vital for sustaining performance, recovery, and overall well-being in athletes.
