Alcohol and Weight Loss

Why They Don't Mix as Well as You'd Hope


There are several reasons why alcohol and weight loss don't mix very well, no pun intended. Alcoholic beverages can significantly hinder progress toward your weight loss goals.

While it may be tempting to unwind with a drink after a long day or celebrate with friends, it's worth understanding the real impact alcohol has on your body and your weight management efforts. Here are nine things you need to understand.


9 ways alcohol hinders weight loss

1. It's high in calories

Alcohol contains 7 calories per gram. That's almost as much as fat, which contains 9 calories per gram. A standard glass of wine is around 120 to 150 calories. A beer can be 150 to 200. Cocktails often exceed 300. These calories add up quickly and make creating a calorie deficit much harder.

2. It has almost no nutritional value

Alcohol is often referred to as empty calories because it lacks essential nutrients like vitamins, minerals and fibre. When you're trying to lose weight, every calorie should ideally do nutritional work for you. Alcohol calories do almost none.

3. It disrupts metabolism

When you drink, your body prioritises metabolising alcohol over everything else. This means fat burning is effectively paused while alcohol is being processed. The result is increased fat storage from the food you eat alongside the alcohol.

4. The liver can't multitask

The liver plays a crucial role in metabolising both alcohol and fat. When the liver is busy breaking down alcohol, it's less able to process fats. This contributes to fat accumulation, particularly around the abdominal area.

5. It disrupts nutrient absorption

Alcohol interferes with the absorption of essential vitamins and minerals. This can lead to nutritional deficiencies that make weight management and overall health harder to maintain.

6. It causes dehydration

Alcohol is a diuretic. It increases urine production and causes dehydration. Dehydration can cause water retention and bloating, making you feel and look heavier than you actually are.

7. It increases appetite

Alcohol lowers inhibitions and impairs judgment, making you more likely to choose high-calorie foods and eat larger portions. Many people consume far more food after a few drinks than they would have sober.

8. It impairs decision-making

Beyond food choices, alcohol impairs the broader decision-making that supports a healthy lifestyle. Going to the gym tomorrow feels less important. The extra serving seems more justified. It's a compounding effect.

9. It affects sleep quality

Alcohol disrupts sleep patterns and reduces sleep quality. Poor sleep is directly associated with weight gain through its effect on hunger hormones, increasing ghrelin the hunger hormone and decreasing leptin the satiety hormone.


How to include alcohol without completely derailing your progress

Nowadays I rarely drink alcohol. When I do, I enjoy a couple of glasses of dry wine with a meal. If you choose to include alcohol occasionally, here are some practical strategies.

  • Moderation is key. Limit to one drink per day for women and two for men at most
  • Choose lower-calorie options. Light beer, dry wine or spirits with soda water or sparkling water rather than sugary mixers
  • Watch your portion sizes. A standard wine serving is 150 ml, not a generously filled glass
  • Plan ahead. If you know you'll be drinking, adjust your calorie intake earlier in the day accordingly
  • Be mindful of mixers. Sugary sodas and fruit juices significantly increase calorie content
  • Stay hydrated. Drink water alongside alcoholic beverages to stay hydrated and reduce the likelihood of overeating
  • Be honest about its effect on your food choices. What you eat alongside and after alcohol often matters as much as the alcohol itself

Alcohol and weight loss aren't completely incompatible. But if weight loss is your primary goal right now, minimising alcohol will make the process faster, easier and more consistent.



Health should feel like your best life, not a break from it.
