PRINCESS2218 56 Posted June 16, 2016 When I go on my pre-op liquid diet. I have to drink Optifast shakes, so I was wondering. Does it cause a lost of appetite? Share this post Link to post Share on other sites
KristenLe 5,979 Posted June 16, 2016 It should be filling but I don't believe it suppresses your appetite. It will not help with the head hunger and the sense you need to "chew" something unfortunately. Share this post Link to post Share on other sites
