Does anyone know if it's OK to use 100% whey concentrate mixed with water or almond milk as a meal replacement? I've been low carbing for a while now but eat far too much cheese, nuts and double cream. I've actually started gaining weight back again even though my diet hasn't changed. I have thought about trying whey protein powder but don't want one with loads of sweeteners etc added so thought about just blending it with cocoa powder and water to make a shake. Was hoping if I did this 3 times a day for a few days I might drop a couple of pounds.
