Here's my concern with what you just said. If it says 25 carbs, you will drink it. But what about carbs in other things? Are you staying below your allotted carb count for the entire day, or are you counting the carbs based on each individual item and not the entire day as a whole? Your allotted carbs for the entire day are much lower than they were pre-surgery, so make sure you're paying attention to that and staying at or below your carb amount for the whole day. For me, I can't go above 50 carbs for the whole day, but I tend to stay at around 30 for the day. You have to watch the protein, fat, carb, and calorie intake now. My nutritionist said my allowable numbers are: Calories - no more than 500 calories per day (based on being where you're at in the process)m carbs: 50 or less, fat: 50 or less, and protein: 60-90g. I just had my revision, so I'll have to start my process over once I'm done with all liquids, but given the guidelines, there's no way I would ever drink anything that was 15, 20, or 25 carbs per serving.
