there are dietary cleanses and diets for candidia. look those up and see if they seem doable to you. cutting out grains and sugars will help, but wont necessarily "cure" you. vegetable carbs are good, but sugar and grain based carbs are bad. you will need to limit your fruit content too.
for a good shake, just use a protein powder (egg white or whey), add some good fat like coconut oil or flax seed oil, and a lot of fruit, like blueberries (i know, i already said to limit your fruit though). you can add raw eggs and raw cream too to up the fat and protein content. vanilla extract helps to add flavor. get a chocolate flavor protein powder and add cocoa powder. stevia helps too to add some flavor. have a few of these each day to up your calorie count. oh, raw colostrum or yogurt is good too, using that in place of say water or almond milk.
the lack of carbs will make it harder for you to put on weight, but you can still keep your calorie count up by eating more fat and protein, which you'll need to do if eating low carb to prevent muscle wasting. this should at least help you maintain your weight.
animal based protein is much better than vegetable based protein as it is much more bioavailable.
