Helen, Carnation's Alsoy and any other formula is not fat free. As an adult, I water it down two to one. For a child , follow the directions on the can of one to one. This product has a good taste. I am remembering my son's formula from 36 yrs ago. It was Mullsoy and a horror. It smelled bad and stained everythingi it came into contact with. What an improvement over the years with the soy bean formulas. BTW, he didn't know any better and to him, it was good. Rosalie NJ
