because the citric acid kicks you out of ketosis
if you're in ketosis and burning fat, it is seriously weird, you just don't feel hungry at all, even on 500 cals a day. if you're not in ketosis, you could eat a monkey's miscarriage all the time. just not worth it.

technically coke zero and dr pepper zero don't have citric acid, so would be ok, but a big part of the reason for doing the diet was to cut back on the amount of diet pop i was drinking, as i just don't have the willpower to get rid of it any other way!
