My friend has been drinking the malic acid flavoured water from tesco all week, she's doing ss+ and I had a bottle yesterday I had a bit off food on Wednesday so was out off ketosis but was expecting to be in ketosis yesterday or today at the latest tested my water with a ketostix and I'm not in ketosis I've had nothing since Thursday bar my 3 shakes a day and sparkling water except for a bottle off the flavoured water yesterday! It's got to be the flavoured water so my friend tested to see if she was in ketosis and she isn't either! But we've both lost weight so can't understand it! Has anyone else gone out off ketosis drinking this flavoured water? X
