Lifting Weights, Drinking Brews: Beer Pairings For The Gym

Drinking beer after a workout session is a common ritual for many, but is it beneficial to drink beer while lifting weights? Alcohol is a diuretic, causing increased urination and fluid loss, which can be detrimental to the body's natural recovery process from training stress. While beer contains electrolytes and carbohydrates, it does not effectively replace the sodium chloride lost through sweat. Alcohol also inhibits protein synthesis, which is essential for muscle repair and growth. However, having an occasional beer after working out is not significantly harmful as long as it is consumed with water and food. Ultimately, the decision to drink beer while lifting weights depends on individual fitness goals and the potential trade-off between social enjoyment and optimal physical recovery.

Beer can be dehydrating

Alcohol also dehydrates the body as it increases the urine produced by the kidneys to process and filter it out of the body. This is why people often urinate more frequently when they drink. The higher the ABV, the more your body has to work to rid itself of the alcohol.

Drinking beer alone won't necessarily dehydrate you, but drinking too much beer in one sitting may cause dehydration. This is because the excess liquid, combined with your kidneys working harder to filter it out, will leave you feeling thirsty. Losing fluids can also offset electrolyte levels, leading to dehydration.

However, some sources suggest that a low ABV beer (less than 4%) can be effective as a post-workout hydrator. The carbohydrates and sodium in beer can be beneficial post-exercise, and it is also tastier than water, which may encourage you to rehydrate more.

Alcohol may delay recovery

Secondly, alcohol can decrease the use of glucose and amino acids by skeletal muscles and impair metabolism during exercise. It can also inhibit exercise-induced rises in glucose concentration and decrease glucose during recovery from anaerobic exercise. Glucose is an important energy source that plays a role in exercise endurance.

Thirdly, alcohol can interfere with muscle protein synthesis, which increases recovery time. Athletes who drink after working out have been shown to have lower rates of protein synthesis than those who don't. Protein synthesis increases muscle size and helps with muscle repair, which affects stamina and strength-building.

Finally, alcohol may make testosterone less available to your muscles over time, and testosterone also plays a role in muscle rebuilding and development.

However, it is important to note that having a drink after a workout once in a while is not likely to have long-term effects. If you are exercising regularly, it is recommended to eat a diet rich in proteins and carbohydrates, such as whole grain bread and cereals, fruit, beans, fish, eggs, cheese, lean meats, and chicken. Carbohydrates provide energy, while protein helps to build muscle and can also be used for energy.

It can interfere with muscle protein synthesis

Alcohol can interfere with muscle protein synthesis, which is the process of repairing and rebuilding skeletal muscle. This interference can occur even when optimal nutritional conditions are met.

One study found that alcohol consumption reduced rates of myofibrillar protein synthesis following a bout of concurrent exercise, even when co-ingested with protein. This means that alcohol ingestion suppresses the anabolic response in skeletal muscle, which may impair recovery and adaptation to training and/or subsequent performance. The study also found that alcohol ingestion in humans suppresses the elevated rates of protein synthesis in skeletal muscle induced by exercise and protein ingestion.

Another study found that athletes who drank alcohol after working out had lower rates of protein synthesis than athletes who didn't drink. The relationship is dose-dependent, meaning the inhibitory effects on protein synthesis are larger the more you drink.

However, one study on mice found that moderate alcohol consumption did not impair overload-induced muscle hypertrophy and protein synthesis. This finding suggests that resistance exercise may be an effective therapeutic modality for alcoholic-related muscle disease.

It may increase recovery time

Drinking beer after a workout can increase recovery time. This is because alcohol slows down the natural recovery process by elevating cortisol levels, decreasing testosterone levels, and inhibiting protein synthesis. In other words, it forces your body to delay the recovery process in order to more quickly eliminate the alcohol from your system.

Alcohol also affects your body's ability to retain water, which is crucial for muscle recovery. Alcohol acts as a diuretic, causing you to urinate more and lose fluids. This can exacerbate the dehydration your body experiences after a workout, as you lose fluids through sweat during exercise.

The impact of alcohol on recovery time is dose-dependent, meaning the inhibitory effects on protein synthesis are larger the more you drink. Research has shown that even when alcohol is consumed with protein after exercise, muscle protein synthesis is reduced by up to 37%. This affects recovery, muscle growth, and adaptation to exercise, especially after resistance training and high-intensity interval training.

However, it is important to note that having a drink after a workout once in a while is not likely to have long-term effects on recovery time. If you are exercising responsibly and drinking in moderation, the impact on recovery may not be significant.

It can be beneficial for social bonding

While drinking beer after a workout may not be beneficial to your body, it can be beneficial for social bonding. Alcohol is a social lubricant, and having a beer with your workout buddies can turn a standard workout into an event or an event into a party. It can be a reward at the end of a grueling experience, and it can help turn the pain of a tough workout into an enjoyable social event.

Races like Tough Mudder and Spartan Race offer beer to participants at the finish line. Race directors know that finishing a tough event is celebratory, and that participants want to hang around with other racers to talk about the experience. Offering beer at the finish line is a way to encourage people to stick around, to cheer each other, and amplify the celebration. And if people end up having a good time, they’re more likely to sign up for more races.

Casey Wetjen, a dedicated runner, points out that she and her husband and their group of running buddies felt that a beer after a training run was a must. It offered a reward at the end of a grueling experience. If a cold beer and bonding time after a gym session make people more likely to exercise, it can be a fair trade-off.

However, it's important to note that drinking beer after a workout should be done in moderation and only occasionally. It's also crucial to prioritize rehydration and refueling with water, food, and a nutritious meal or snack consisting of carbohydrates and protein.
