Why are calories in alcohol so bad for you?

Because alcohol is made from sugar or starch, it contains lots of calories, equalling around seven calories per gram. Calories from alcohol are 'empty calories' and have no nutritional value. 

What does drinking alcohol mean for weight loss?

If you are drinking regularly, you may be consuming higher numbers of calories than your body can burn off during the week. If this calorie surplus continues over time then you are likely to struggle to lose weight.

Drinking alcohol can also have a negative impact on how your body processes the other essential nutrients you consume. Your body cannot store alcohol, thus it prioritises getting rid of alcohol from your system over the absorption of things like proteins, vitamins and minerals and interrupts the burning of fat for energy meaning weight loss is slowed down.

How do you calculate alcohol calories?


If you can't find your drink in our alcohol calorie counter, you can work out your alcohol calories for yourself with this handy rule:

1 gram of alcohol = 7 calories 

The standard drink contains 10 grams of alcohol so this would be 70 calories purely from alcohol. 

This does not factor in the calories from any sugary drinks you mix with alcohol. This is why drinks such as cocktails are so high in calories. 


Consider the number of calories in popular alcoholic drinks:


  • There are usually 220 calories in a large glass of wine
  • They can be around 180 calories in a pint of beer
  • There are roughly 100 calories in vodka
  • There are 65-70 calories in a shot of tequila
  • There are around 120 calories in a gin and tonic

Is alcohol free better for you?
