Pure spirits such as vodka, gin, whisky and tequila are fine as they all contain 0 carbs. The mixers with these drinks could be a problem for some people. Don’t obviously add sugar sweetened mixers to these spirits. With vodka for example you could try adding soda water and a twist of lime which will keep it at 0 carbs. And for those who like coke with their vodka, make sure it is diet or zero sugar. Avoid adding juices and sweet flavourings to your spirits.
Wine is a lot lower in carbs than beers and this is a choice for many on the keto diet. If you are trying to keep your carbs under 20g a day, a glass of wine is usually fine. Still be cautious though. A dry wine contains around 0.5g of carbs a glass which is a fairly keto friendly wine. A sweet desert wine however contains much more sugar.
For those of you who are beer drinkers, then there is more of a problem on keto. There are not many keto friendly beers out there. Take a look at the number of carbs on a 330ml bottle of a tequila beer for example. It will take up most of a persons carb intake for the whole day. Many men start the keto diet in order to get rid of their beer belly in the first place. So if that is the reason, then finding low carb beers is the only way, and then sticking to just a couple.
