Almond and Soy milk
Here is some information about the carb content (in grams) in specified serving volumes of various drinks. As you can see unsweetened almond milk has a lower carb-count than cow’s milk. For cow’s milk the carbs are the same whether it is skimmed or full cream. One site lists unsweetened almond milk as having 1.4g in 1 cup/240ml. Sweetened almond milk came in with 16g, a huge difference. I highly recommend the dietdoctor.com website. See some of their links and data below.
Dietdoctor.com has recently changed policy on soy products including soy milk. As long as you do not have an underactive thyroid they see no reason not to consume soy products. It may be that they are trying to appeal to Vegan folk. The carb count in 100ml of unsweetened soy and cow’s milk is 0.5g and 4.5g respectively. Sweetened soy milk it can deliver 12g/100ml.
This policy was news to me however personally I still have ethical and health worries. Most soy is grown in Brazil (where there are real worries about deforestation to increase agricultural land) and the USA (where there are concerns about pesticide residues in the seed). Up to you. https://www.dietdoctor.com/changes-to-the-diet-doctor-soy-policy
The data presented below came from an article on dietdoctor.com. I guess the soy milk listed here is sweetened. (https://www.dietdoctor.com/low-carb/keto/drinks)

Remember that a strict keto diet, keeps carbs very low. It is typically best to keep carbs from drinks as close to 0 as possible and to use your carb allotment for foods such as fresh vegetables. Below is a detailed list of the number of grams of carbs in a typical serving size of various drinks.
Water 0 (The clear winner)
Water with lemon 0
