I think any extra, empty calories are not really a part of healthy weight loss, even occasionally. People shouldn't go down the slippery slope of one drink a week doesn't impact it, so I'll keep adding more. Was just trying to make sure people are cautious.
FitVine is great! I am 11 months out and I drink with no issues. Of course, it will slow down your progress. It can keep you from drinking sufficient water, has a lot of sugar still and are empty calories.
