Still haven’t adopted the totally clean-eating lifestyle and enjoy going out to the bar for a few drinks? You might want to think twice if you aim to keep all that muscle mass you have worked so hard for in the gym. Consuming large quantities of alcohol directly affects your metabolism by causing dietary fat to be stored instead of being used as an energy source. Among the effects of heavy alcohol consumption on your body, blood flow is reduced to the muscles, causing deterioration and weakness. Alcohol decreases testosterone in your blood and raises conversion of testosterone to estrogen, leading to increase fluid retention and fat depositing. It creates imbalances in your liver that can cause hypoglycaemia, hyperlipidemia and fatty liver. A night out of drinking can stop any progress you want to make in the gym the next day because of dehydration that decreases physical performance. The disturbance of sleep caused by alcohol can leave you fatigued and your training session severely lacking in intensity. Alcohol consumption can also interfere with nutrient breakdown and absorption, lessening the body’s ability to build and maintain muscle. Keep alcohol drinks to a minimum and plan them for evenings when the next day is a break from the gym.
