A few weeks ago we mentioned that alcohol has about 7kcal (7 calories) or 29kJ per gram of energy locked up in it. That's without even thinking about the sugars that are in some alcoholic drinks. If you want to really dive in to the whole thing there's a great article here
Most people don't think about how many grams of alcohol are in the glass or wine or beer they're drinking around the Christmas Dinner table, or out at a bar. So lets change that in to real world numbers.
A standard drink contains 10g of alcohol.
32ml (1 Shot ) of 40% Vodka
330ml (a Standard Can) of 4% Beer
100ml of 13% Wine
Are all standard drinks. They each contain about 10g of alcohol.
So the maths works out like this
10g Alcohol x 7kCal per gram = 70kCal
So there are roughly 70kCal per standard drink.
I like to think about calories in terms of what do I have to do to burn them off. We talked about the amount of energy exercise burns a while ago.
An 83Kg person walking at 5.5Km/h for 30 minutes would burn roughly 200Kcal or 6.67Kcal per minute.
So the maths for burning off ONE standard drink looks like this
70Kcal / 6.67Kcal per minute = 10.5 minutes
2 and a half times around a 400m track or
around the square in Palmerston North One and a Quarter times
For each standard drink.
