ive been on the keto diet for 4 weeks now & my weight has gone from 215 lbs to 195 lbs. so i thought the diet was working well. so i got my skin folds done again. they have hardly gone down.i look soft & flat.ive been in contest shape before so i know how to get into shape. everybody has been raving about how good the keto diet is, i thought i would give a try . so far i have found it to be the worse diet i have ever done.what am i doing wrong?
