Hey guys, my dad is a diabetic. He has gotten his sugar under control but has lost a lot of weight. Is there a good sugar free weight gainer out there. He has started taking sugar free ensure (glucerna). I was wondering if there are other weight gainers out there. I have looked up on my own but figured you guys would have the best answer. Also lactose free would be good to avoid all the access bloat. Thanks for all your help.
