This month, we are providing information on various health topics, beginning with the impact of alcohol on weight loss. When striving to lose weight, the general advice of consuming fewer calories than you burn still holds true. However, not all calories have the same effect on your body. For instance, 300 calories of broccoli will have different effects on your blood sugar and metabolism compared to 300 calories of cake. But what about 300 calories from alcohol?
Whether it’s beer, wine, or a cocktail, it turns out that alcohol has specific and unique effects on your body’s systems. Some of these effects can make it more challenging to lose weight, maintain weight, and stay active.
If you’re finding it difficult to lose weight despite maintaining a healthy diet and exercise routine, it might be time to examine your alcohol consumption, including the type and quantity.
Impact of alcohol on the body
As enjoyable as a mojito or craft beer may be, and as often as it serves as a stress reliever or a social drink, alcohol does not benefit your body in any way. Even the previously touted cardiovascular benefits of red wine have largely been disproven.
Alcohol negatively affects various systems in the body. In the short term, it can affect muscle performance by inhibiting the absorption of calcium in muscle cells, which can lead to cramping.
Regardless of the type of alcoholic beverage, alcohol itself acts as a vasodilator, temporarily widening the blood vessels. That’s why most people feel warmer when they drink. Ironically, despite feeling warm, your core body temperature actually decreases. Additionally, alcohol’s diuretic effects can contribute to dehydration, affecting all organs and systems, including digestion.
However, the aspect most relevant to weight is alcohol’s impact on your liver’s ability to process sugar and its interference with overall nutrient absorption.
Alcohol contains 7 kcal/g and can contribute to weight gain when consumed excessively. Nonetheless, moderate alcohol consumption does not appear to result in significant weight gain, if any at all.
Possible indirect effects
Apart from the direct physical mechanisms caused by alcohol, there can also be secondary effects. Anyone who has made a fast-food stop after the bar closes is familiar with this phenomenon. Alcohol lowers inhibitions and can alter your normal control over eating.
Alcohol may also disrupt your sleep patterns, particularly the amount of deep, restorative sleep you experience. This effect can be particularly pronounced if you consume alcohol within a few hours of bedtime. The National Sleep Foundation (NSF) estimates that as many as 20% of Americans have an alcoholic drink to help them fall asleep. However, while alcohol may induce sleepiness, it tends to compromise the overall quality of your sleep. It can disrupt your circadian rhythm, impede restorative REM sleep, and exacerbate breathing problems.
When your sleep quality suffers, it can impact your athletic performance and even deter you from exercising altogether. Those who feel groggy, even without being hungover, may choose to forgo exercise in pursuit of restorative sleep. However, if the evening brings another round of drinking, accompanied by subpar food choices and more poor-quality sleep, you may find yourself caught in a cycle that hinders the achievement of your goals.
Striking a balance between drinking and weight loss
Despite the potential negative effects of alcohol, most health experts suggest complete sobriety as a requirement for weight loss. Moderation remains key, defined as one drink per day for women and two drinks per day for men. Consuming even less is even better. While moderate drinking ranges from 1 to 2 drinks per day, there is growing evidence suggesting that consuming alcohol less than once per day is healthier.
However, they recommend that if your weight loss progress has stalled, or if you have other health issues possibly linked to alcohol consumption, such as low energy or poor sleep, it may be worthwhile to try a “dry week” or even a “dry month” to observe the effects of abstaining from alcohol. For some individuals, this break can reignite weight loss efforts and establish healthier habits regarding food and exercise.
You don’t have to give it up for life if you don’t want to. But taking a break is often more beneficial than simply switching to low-sugar or low-calorie options or cutting back. And when you do decide to resume drinking, pay attention to how it affects you.
Examining your habits more closely
It is important to note that if you have been attempting to reduce your alcohol consumption and find it impossible, there may be underlying issues beyond weight management. In such cases, it may be helpful to seek resources that can assist you in evaluating your relationship with alcohol.
The National Institute on Alcohol Abuse and Alcoholism, as well as the National Council on Alcoholism and Drug Dependence, can serve as valuable starting points.
Even if you are confident that alcohol is not a problem, taking the time to increase your awareness of how much you are drinking can be beneficial in maintaining a healthy lifestyle and supporting your weight loss efforts.
