Yes, it can. If you drink it as well as eat a "maintenance" diet then it will aid in weight gain. =) Ensure does as well.
I would like to know if pediasure aids weight gain. I will appreciate your response.
The purpose of it is the same as Ensure. There are several different reasons one may have to drink it. Why do you ask, and perhaps I can be more specific in answering the question? =)
