Building Muscle And Drinking Beer: Is It Possible?

Drinking beer and building muscle is a tricky combination. Beer is often associated with social bonding and celebration, but it is essential to consider its impact on muscle growth and recovery. While moderate drinking is generally defined as one beer per day for women and up to two beers per day for men, excessive consumption can negatively affect workout recovery and muscle growth. Alcohol interferes with the body's ability to repair and rebuild muscle, and its calorie content can contribute to weight gain, hindering the desired results of a training programme. However, some studies suggest that a single beer after exercise won't undo the hard work, and beer also contains B vitamins and carbohydrates that can support energy levels. So, can you drink beer and still build muscle? The answer is nuanced. While it may not be advisable to rely on beer as your primary post-workout beverage, occasional and moderate consumption, combined with a balanced diet and proper hydration, may be possible without completely sabotaging your fitness goals.

Alcohol and testosterone

Testosterone is the primary male sex hormone. It gives men their masculine features and is responsible for sex drive, bone and muscle growth, and sperm development. In women, testosterone is produced in small amounts in the ovaries, and low levels can lead to low libido and brittle bones.

Drinking alcohol excessively can cause short-term and long-term changes to testosterone levels. Alcohol can disrupt testosterone production by interfering with the three glands responsible for its production: the hypothalamus, anterior pituitary gland, and testes.

Long-term effects of alcohol on testosterone

Heavy drinkers are more likely to experience poor testicular function than moderate drinkers. Heavy drinking is usually defined as more than 15 drinks a week for men or more than eight drinks a week for women. Long-term alcohol misuse is thought to damage Leydig cells in the testes, which are responsible for testosterone production. It may also interfere with the release of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and gonadotropin-releasing hormone (GnRH).

Short-term effects of alcohol on testosterone

Acute alcohol consumption can cause short-term impairments in testosterone release by negatively affecting the hypothalamus and pituitary gland. Research has found that testosterone levels can drop in as little as 30 minutes after drinking.

Alcohol and muscle growth

Alcohol consumption impairs muscle protein synthesis (MPS), which is a key marker of muscle growth. A study found that alcohol consumed with protein reduced MPS by 24%, and by 37% when combined with carbohydrates.

Reversing the effects

While generic treatments for low testosterone may help those whose alcohol consumption has affected their testosterone production, there is currently limited research on reversing alcohol-related low testosterone.

In conclusion, excessive alcohol consumption negatively impacts testosterone levels and muscle growth. Moderate drinking, usually defined as no more than one drink for women or two drinks for men in a day, does not seem to have the same effects as heavy drinking. However, even moderate drinking can interfere with testosterone production and muscle recovery, so it is important to drink in moderation or abstain completely if you are concerned about maintaining optimal testosterone levels and supporting muscle growth.

Alcohol and muscle growth

Alcohol is often associated with rapid weight gain and poor health. However, research shows that drinking 1-2 drinks a few times a week can have some health benefits, including improved insulin sensitivity, reduced risk of hypertension, and improved heart health. So, what does this mean for muscle growth?

Alcohol and Testosterone

Testosterone is a key hormone for muscle growth and performance. While low doses of alcohol (about two beers for a 150-pound person) have been shown to increase circulating testosterone by about 17% in both young men and premenopausal women, this boost is likely not significant enough to noticeably increase muscle growth. On the other hand, heavy drinking (seven beers for a 150-pound person) has been found to suppress testosterone levels. Additionally, moderate amounts of alcohol (three to four beers) consumed daily for at least three weeks can mildly suppress testosterone levels.

Alcohol and Muscle Protein Synthesis

Research has shown that alcohol can impact muscle protein synthesis, the process by which muscles grow and repair. A study found that consuming 71 grams of pure alcohol, or approximately five beers, suppressed protein synthesis by 24%. However, consuming just two standard beers did not have this effect. Another study showed that for a 150-pound person, consuming the equivalent of about seven beers suppressed muscle protein synthesis, even when consumed with 25 grams of protein. Animal studies also support this, as muscular protein synthesis rates in rats were suppressed after they received ethanol injections. Overall, this evidence suggests that drinking more than five beers in one sitting could impair muscle growth and workout recovery.

Alcohol, Recovery, and Performance

Alcohol can also impact recovery and performance. One study showed a loss in force production and impaired recovery after consuming alcohol. Additionally, alcohol consumption can reduce glycogen storage, which is important for muscle fuel. However, these studies involved excessive alcohol intake and rigorous training regimes that may not be applicable to the average person.

So, Can You Drink Alcohol and Still Build Muscle?

While alcohol does have some detrimental effects, these can be minimized to allow for social drinking without sabotaging muscle growth. Research suggests that drinking about two beers won't undo your hard work at the gym. Additionally, drinking in moderation can have social benefits that may help you stick to your fitness routine. However, heavy drinking or binge drinking can lead to severe health problems and negatively impact your sleep, nutrition, and recovery. Therefore, the key to including alcohol in your diet while building muscle is moderation.

Alcohol and fat reduction

Alcohol is shown to reduce metabolism and decrease the body's ability to burn fat. This is because the body sees alcohol as a toxin, not a nutrient, and so it is unable to store alcohol calories in the same way as food calories. Instead, metabolism shifts from burning stored food calories to removing toxic waste. The primary toxic chemicals produced by alcohol are acetaldehyde and acetate.

The body's prioritization of metabolizing alcohol over everything else means that the digestion of fat, carbohydrates, and protein is halted until all the alcohol has been cleared from the body. A study found that total body fat oxidation was reduced by 79%, protein oxidation by 39%, and carbohydrate oxidation was "almost completely abolished" after alcohol consumption.

However, it's important to note that alcohol itself doesn't make you fat. While alcohol has 7 calories per gram, which is nearly twice as much as protein and carbohydrates, research shows that due to the high thermic effect of alcohol, the actual amount metabolized by the body is about 80%, making the actual calorie count closer to 5.5 kcal per gram.

Alcohol consumption tends to lead to an increase in food intake, probably by enhancing the short-term rewarding effects of food. However, it is not the lead contributor to weight gain. Researchers give more weight to an individual's personality and habitual beverage preferences. So, if you drink high-calorie drinks every night in moderate excess, you will likely gain weight. On the other hand, if you drink lower-calorie drinks less frequently, alcohol is unlikely to contribute to weight gain.

In summary, alcohol suppresses fat oxidation, allowing the body to store fat and carbohydrates more easily, but the conversion of alcohol into fat is minimal. Ultimately, if you drink alcohol and are in a calorie surplus, you will gain weight, and if you drink alcohol but remain in a calorie deficit, you will lose weight.

Alcohol and sleep

While alcohol might help you fall asleep, even a couple of drinks can affect the quality of your sleep. The alcohol in your system will mean you spend less time in the important REM stage of sleep, with the end result that you wake up feeling less refreshed. Even just a couple of drinks will have an effect.

Several sleepless nights can have an impact on your day-to-day mental function—for example, your mood, concentration, and decision-making.

Drinking can also make you snore. It relaxes the muscles in your body, which means the tissue in your throat, mouth, and nose can stop air from flowing smoothly and are more likely to vibrate.

More seriously, alcohol increases the chance you will suffer from sleep apnoea—a condition that narrows your airways and can stop you from breathing properly at night. Without treatment, sleep apnoea can lead to type 2 diabetes, depression, high blood pressure, and increase your chance of having a stroke. It may also affect your mood and concentration and make it more likely that you will have an accident because you're tired.

Alcohol and nutrition

Alcohol lacks nutritional value and can impair nutrient absorption by disrupting the digestive system. It interferes with the body's ability to absorb protein and other essential nutrients, which are crucial for optimal fitness levels and muscle maintenance. Additionally, alcohol is considered a toxin by the body, leading to a shift in metabolism as the body prioritises removing toxic waste over burning stored food calories. This disruption can result in reduced fat oxidation and increased fat storage.

However, consuming 1-2 drinks a few times a week has been linked to improved insulin sensitivity, reduced risk of hypertension, and potential benefits for cardiovascular health. Moderate alcohol consumption may also positively impact cholesterol levels and electrolytes, contributing to better hydration and blood pressure control. These health benefits are supported by studies examining the effects of moderate drinking on heart health.

When it comes to muscle growth, the impact of alcohol depends on the amount consumed. Heavy drinking, defined as more than three drinks per day for women and more than four drinks per day for men, has been found to suppress muscle protein synthesis (MPS) and impair workout recovery. On the other hand, limited evidence suggests that consuming one or two drinks does not significantly affect MPS or hinder muscle growth. Timing also plays a role, as research indicates that drinking after training is preferable to drinking during the body's recovery period.

To minimise the negative effects of alcohol on muscle growth and nutrition, several strategies can be employed:

• Consume no more than one drink per hour to allow your body to metabolise the alcohol effectively.
• Stay hydrated by alternating between alcoholic drinks and water.
• Choose low-calorie drink options, such as dry white wine or clear spirits with a diet mixer.
• Consume adequate protein, especially if drinking post-workout, to mitigate the negative impact on MPS.
• Be mindful of your drinking frequency and limit excessive consumption, as regular binge drinking will negatively affect your fitness goals.

In conclusion, while alcohol may not be the ideal beverage for optimal nutrition and muscle growth, it is possible to include it in your diet without sabotaging your progress. The key lies in moderation and being mindful of its potential impacts on your body.
