I’ve been using Soylent for a couple years. I’ve done everything up to 100% Soylent for some periods of time.
I always have Soylent for breakfast now, but have found over time that I NEED solid food for lunch. There is just something about looking forward to lunch time solid food when working a long day at the office.
Mostly though, I have actually gained weight on Soylent. I crave it; use it for late night snacks, breakfast, between lunch and dinner, while still eating more “real” meals than I should. It just does not fill me up for very long and is very high calorie.
I usually make a 2000 calorie pitcher a day, and try to share some with the fiance to reduce how much I consume.
