Though there was debate about whether or not the drink qualified as keto after it went majorly viral, it basically is. All it's made of is unsweetened Peach Citrus White Tea, heavy cream, 2-4 pumps of sugar-free vanilla syrup, and ice. Rum, whiskey, tequila, vodka, gin, and all other liquors in the same vein are keto-friendly, as long as you're not mixing them with juices or caloric sweeteners of any sort. Tonics, sodas, and seltzers are your best friends when it comes to keto mixers. By the aforementioned logic, all no-calorie seltzers are keto as well.
