Soylent does not recommend any number of calories a day.
they sure do, the standard 'dosage' is 2k cals per day and they have a calculator (that you have to dig for) if you figure your requirements differ from the 2k cals per day. Nevermind the fact that these types of calculators of woefully inaccurate.
The FDA guidelines do not recommend any number of calories a day. The % DV is based on the recommended amounts for a 2,000 calorie diet, and there is a standard, required, footnote noting this and that actual DVs vary by calorie needs.
