 The modified Atkins diet reduces seizure frequency by more than 50 % in 43 % of patients who try it and by more than 90 % in 27 % of patients . Few adverse effects have been reported , though cholesterol is increased and the diet has not been studied long term . Although based on a smaller data set ( 126 adults and children from 11 studies over five centres ) , these results from 2009 compare favourably with the traditional ketogenic diet .
