What are the benefits of reducing your alcohol intake?

Cutting back on alcohol can improve your mental and physical health in a number of ways, including:

1. Weight management

Alcohol is made by fermenting (and sometimes distilling) starch and sugar. Because of this, it’s high in calories, supplying 7 kcals/g – almost as much as fat, which provides 9 kcals.

Calories from alcohol are typically described as ’empty calories’ because they provide no nutritional value. Some alcoholic drinks contain traces of vitamins and minerals, but not in sufficient amounts to contribute to a balanced diet.

When you drink alcohol, your body also burns less fat as energy. We can store nutrients, protein, carbohydrates and fat in our bodies, but we can’t store alcohol, so our bodies try to process it as soon as possible. This disrupts the other processes that would usually take place, including those involved in absorbing nutrients and burning fat.

Swapping alcoholic drinks for non-alcoholic options that are lower in sugar and calories can be a great way to cut down on calories and help you manage your weight.

2. Better sleep

You might think alcohol helps you nod off, but the truth is that even just a few drinks can disrupt your sleep cycle and make you feel tired and sluggish. When you fall asleep after drinking, you may fall into a deep sleep more quickly than usual, but over the course of the night, you actually spend less time in deep sleep and more time in the REM (Rapid Eye Movement) stage of sleep, which is much less restful. This means you’re more likely to wake up feeling tired, even after a full night in bed.

In contrast, having alcohol-free days may help you sleep better and wake more refreshed the next morning.

3. Better mental health

Alcohol is a depressant, which means it slows down the brain and central nervous system. So, while it may make you feel more confident and relaxed in the short term, in the long term it can contribute to feelings of anxiety and depression.

Say no to drinking and you could miss out on the low mood caused by poor sleep, dehydration and horrible hangovers.

4. Better long-term physical health

The more alcohol you drink, the greater your risk of developing a number of serious, potentially life-limiting health conditions, such as pancreatitis, liver disease, some types of cancer and diabetes.

However, reducing your intake so that it is within the low-risk guidelines will help keep your risk of alcohol-related harm low.

5. May lower blood pressure

Dr Gautam Mehta, senior lecturer at the UCL Institute for Liver and Digestive Health, co-authored a paper on the benefits of periods of abstinence, such as Dry January. He says:

“Our work has shown that a month off alcohol, in healthy individuals drinking at moderate to high levels, does lead to tangible health benefits by the end of the month. Our study saw a weight loss of around 2kg, a decrease in blood pressure of around 5 per cent and improvement in diabetes risk of almost 30 per cent. However, it’s important to note that we don’t know how long these benefits last, or whether they translate to long-term improvements in health.”

6. Improve brain function

Alcohol slows down the communication between your brain and the rest of your body. It also limits your ability to retrieve memories. People who are dependant on alcohol may suffer from disorders of the brain due to excessive drinking.

Giving up drinking alcohol puts you at a lower risk of developing these disorders, and may improve brain function over time.

7. Good for heart health

Excess drinking produces free radicals in the body that cause any ‘bad’ cholesterol (LDL) to oxidise, which may eventually block arteries.

Therefore, reducing the amount of alcohol you drink decreases your risk of cardiovascular disease.

8. More energy

Cutting out alcohol hugely improves the quality of your sleep, so you’ll likely feel more energised. Without the dehydrating effects of alcohol, you may also notice that your mind is more clear and you experience less brain fog. What’s more, you won’t be reaching for sugary and carb-heavy foods to give you a quick release of energy, only to suffer from crashes later on.

9. Glowing skin and eyes

Alcohol dehydrates your body, which can leave your skin and eyes looking dull. If you cut back on the booze, you may notice how healthy, hydrated and well-rested you look.

10. Less fat around the liver

Drinking more than the recommended amount (two drinks a day for men, one for women) causes fat to build up around the liver. This is concerning, as the liver is vital for filtering toxins from the blood, aiding the digestion of food and balancing blood sugar levels.

The good news is, fatty liver disease is reversible – once you stop drinking, the liver should begin to slowly recover.
