I recently had oral surgery and needed to go on a completely liquid diet for a few days. While I have used Soylent for several years I had never tried to live on it. I was pleasantly surprised that I was able to consume less than 2000 calories in a day and still feel satisfied. I no longer need to be on a liquid diet but I’m extending it a few weeks as I’m losing some unnecessary pounds and I feel great. I’ve had no digestive problems or suffered other issues that some have described. Definitely going back on solid food soon but it will be much less than I ate before. I’ve always been concerned about the higher fat content in Soylent but perhaps that’s why I feel so satisfied with 4 bottles a day.
