Alcohol consumption can significantly impact fitness goals by impairing performance and recovery. Excessive alcohol intake leads to dehydration, which can hinder performance during workouts and increase the risk of injury. Moreover, alcohol has high calorie content and may contribute to weight gain when consumed in excess, undermining weight-related goals. It can also disrupt sleep patterns, negatively affecting recovery and hormone balance critical for muscle growth. Moderation is key; minimal alcohol consumption may be less detrimental, but heavy drinking can derail fitness progress.
