I bought a week's worth of Ensure Complete and was unable to sustain any sort of meal replacement plan on it. Each drink only seemed to alter the 'flavor' of my hunger rather than sate it in any way.

Liquids are nowhere near as effective at satiation as solids.

Fibre and protein can increase the satiety of a drink, though.

You can add fibre, if you think that's going to help.
