Hi all, not on Exante but thought I'd drop a note here... Coke and DR Pepper Zero have Malic acid in them (as opposed to Diet Coke etc with CITRIC acid in them). Citric acid WILL knock you out of ketosis, MALIC will NOT... It is recommended that it is drunk in limited quantities due to bloating, possible 'hunger' or making your body/brain crave further 'real' food. So in short, yes drink it, but also be aware of how your body responds...
