I'd love to know this, too. I've lived my life for such a long time doing the low fat thing--and I really prefer it, taste-wise (probably not alone here?) There are days when I have a real problem making myself eat the meat, eggs, etc., and I don't get enough. I'm just not sure about the right shake to buy. I looked at GNC the other day, but there seemed to be lots of sugars and carbs in everything I saw. Any suggestions for me?
