i think this is a personal choice really. some people swear by it to keep them on track while others are much more "by the book" and won't stray from water/tea/coffee. i think it depends on the individual, for me, i wouldnt have it all the time, but with 9st to lose having it to look forward to as a treat is a nice motivator xx
For me I drink nothing but water and green tea (and decaff coffee in my vanilla shake) but thats more a health thing than an Exante thing. Ive been doing it ever since I started dieting as I figured if I was going to go to the bother of losing weight I may as well do my best to get healthier at the same time.
Just warm water. When ill a few years ago I was advised to give up caffeine, so I did. God was it a struggle, I love coffee. Having said that I did treat myself to a warm vanilla & coffee shake & I loved it. It’s too cold & wet here to be sipping cold water so I have it warm/lukewarm. It’s all a very personal choice though.
I don't think there's anything in Coke Zero than can kick you out of ketosis it's the Citric Acid in other diet drinks like Diet Coke that can kick you out of ketosis. Coke Zero can make you feel hungry though in my opinion anyway.
