I also give my husband Designer Whey Protein powder. He lost 50 pounds and has gained 30 of it back and is stable at this weight for the past month or two. He gets about 3200 calories a day. I cook a scrambled egg and put it in the blender with protein powder and milk and it is an eggnog. The egg completely liquifys. He also drinks three drinks a day with ensure, instant breakfast, protein powder, bananna, and yogurt which comes to about 850 calories at a time. He gets 400 extra calories by adding the protein powder to his drinks
