Yes, I heard the same thing. That citrus acid stalls your weightloss. Which I have also heard too that they aide in weightloss. But, I had and have been drinking the flavored water with splenda and citrus acid in it for awhile, and I don't believe that it has anything to do with the lack of the weight going down. Most of the SF sodas and SF drinks out there have citrus acid, and a lot of the foods have it too.
All you can do is try the drinks and foods and see if it stalls you, if so don't drink them and eat them. If you find you do not stall, drink and eat the foods with the citrus acids!
I also heard that drinking lemon juice aides in weightloss.
Wonder if that is so?
Good Luck!
