Honestly, this is a hard question to answer, since keto is a metabolic state. Keto isn't a food! Ketosis is basically the absence of carbs and sugars, and using fat for fuel in your body. While some foods are higher in carbs and sugar than others, we believe in eating what you want to an extent. When you're first starting out with a low carb lifestyle, it might be easier to limit some things, but in time, we have found that moderation for us is key. Alcohol in general can be known to kick people out of ketosis, because alcohol will be used for fuel before any other food source. After alcohol, your body will turn to carbs for fuel, and then lastly, fat burning! Basically, on nights of heavier drinking, your body is running off of alcohol before anything else. When you add extra sugars and carbs to the mix with your alcohol, things can get a little tricky. Many spiced rums have tons of extra sugar, so keep an eye out for that.
