I use 2 dspoons each of ground almonds & coconut flour, made up with boiling water. I have it at b'fast supplemented with milled flax seeds & oat bran, & at night supplemented with low cal drinking choc. I always take a multivitamin/mineral supplement to ensure I get adequate nutrition. Sometimes I use soya or cows' milk, & m'wave to boil. Add cup-a-soup for lunch.
