I had to give up on the formulas from Nestle (IsoSource and Nutren) - I couldn't tolerate them (let's just say they raced their way through my system and left me depleted). I found the website for tubies and have used some of their information to create my own blenderized recipes. I don't use a pump, only gravity (no plunger). There are two keys that I have found that help: blending your mixture long enough (sometimes this takes more than a few minutes) and dilution with enough water. This is important not only with my home made recipes but also with the Liquid Hope (which I am a big fan of because of the nutrition it delivers) as it is very thick.

If your hubby has only lost 4 pounds then you are doing a great job getting nutrition into him! Keep on plugging away and trying new things. If he is still in treatment (I realize I am late to the dance here) you might want to blanch any raw foods you include in the blender versions to cut down on exposing his depleted immune system to anything that might linger after thorough washing).

Prayers your way,

Heather
