This is what happens, When You Cut Out Alcohol
Cutting out alcohol if you drink in excess can bring about health benefits for your liver, heart, and body composition.
1. Liver relief
Cirrhosis of liver can occur over time in those who drink excessively.
“It doesn’t happen in a day, but for anyone who drinks in excess, which again is more than two drinks a day for men, and one a day for women, there are fatty changes in liver, so when you stop drinking, those changes are reversible and the liver can become normal again,” said Dasgupta.
Because the liver is a tolerant organ, he said positive changes can occur within weeks of going dry.
Kumar added that in the absence of alcohol, “the liver can focus on its other jobs, such as breaking down other toxins produced by the body, metabolizing fats and excess hormones that need to be broken down.”
2. Decrease risk of cardiovascular disease
Alcohol is metabolized by the liver and an enzyme called dehydrogenases. However, when you drink in excess, the enzyme gets saturated and is metabolized by a different enzyme.
“When it’s metabolized by this different pathway, it produces lots of free radicals which is known to oxidize bad cholesterol (LDL), and when the LDL is oxidized it deposits on the carotid arteries forming [blockage],” said Dasgupta.
On the other hand, if you drink in moderation, alcohol doesn’t have any effect on LDL, and instead increases good cholesterol (HDL).
“Drinking one or two glasses of wine once or twice a week has some health benefits, especially for men over 40; it reduces risk of cardiovascular disease… for women you can get those benefits anytime, it’s not age-dependent,” Dasgupta said.
However, he notes that people of Chinese and Indian descent do not get the benefit of drinking alcohol due to a genetic reason that isn’t clearly known.
“[The bottom line] is, protect the heart with low amount of alcohol, but increase the risk of cardiovascular disease with high amount of alcohol,” Dasgupta said.
To better your heart further when cutting out alcohol, he suggests adding in exercise, which also increases good cholesterol.
3. Reduce risk of cancer
The National Toxicology Program of the U.S.
Department of Health and Human Services lists alcohol as a known human carcinogen in its Report on Carcinogens.
The report states that a person’s risk of developing an alcohol-associated cancer increases with the more alcohol they drink regularly over time. Links are shown between alcohol consumption and the development of the following types of cancer:
head and neck
Data from 2009 published in the American Journal of Public HealthTrusted Source estimated that about 3.5 percent of cancer deaths in the United States were alcohol related.
4. Weight loss
While alcohol is high in calories, and wine, beer, and mixed drinks add sugar to one’s diet, Kumar says cutting it out may or may not help to lose weight.
“Again, depends on what the baseline alcohol consumption is. If heavier drinkers remove alcohol for a longer period of time, they might see weight loss, improvement in body composition, less stomach fat, improvement in triglycerides (one of the fat particles in the blood),” she said.
Depending on the patient, she said she sometimes suggests cutting back on alcohol to lose weight.
“I have recommended completely eliminating alcohol for weight loss as a trial for some patients who have optimized all other aspects of their life (diet is pristine, exercise is maximal, sleep is adequate, stress is managed) to see if they are particularly sensitive to the weight gaining effects of alcohol,” said Kumar. “For instance, many women around menopause report gaining weight from alcohol much easier than they did prior to menopause.”
“I would suggest cutting back on several things rather than completely eliminating to avoid feeling deprived, which can lead to rebound eating/drinking and weight regain,” she said.
5. Boost brain power
Dasgupta says the best people to practice Dry January and being dry all year-round are those under 21 years old, and not just for legal reasons.
“There’s a reason why the legal age of drinking is 21 years. Teenage and college drinking is a huge problem. It can cause memory loss and interference with brain development. For college students, being dry is the best thing to do,” he said.
Same goes for those with alcohol use disorder or for those with a family history of it.
“Alcoholics have some specific disorders of the brain which are due to excess alcohol drinking. Brain damage can reduce memory and concentration,” said Dasgupta.
Those who drink more than the recommended two drinks a day for men and one drink a day for women may be at the risk of all the above 5 health benefits.
