Excessive alcohol consumption can negatively impact fitness by disrupting metabolic processes and impairing recovery. Alcohol can dehydrate the body, leading to reduced exercise performance and increased risk of injury. It may also increase body fat due to its high caloric content while inhibiting muscle protein synthesis, which is crucial for repair and growth. Additionally, alcohol can disrupt sleep quality, impairing recovery further. Overall, frequent heavy drinking detracts from fitness goals by compromising both physical performance and overall health.
