I am looking into starting a Keto diet. Trying to run between 3500 and 4000 cals while keeping carbs at 50 grams per day, and fat under 125 grams. I am having a hard time finding anything to drink that has zero or very few carbs in it. Soda is out, and any kind of juice is out, etc, etc. Any suggestions??? I would like to drink something with some kind of caloric value to help up my calorie intake.
