@Scot, the four meals vs. three still assume that all four meals are being consumed in a day. Soylent isn’t recommending you cut down to just three servings a day (although they aren’t recommending you don’t." They are more suggesting that you break down your Soylent consumption from three daily servings to four daily servings.
One whole bag still contains 100% of daily value of nutrients and calories, whether you consume your full pitcher in three or four meals. If you are saying you are cutting down to just three of the newly-reduced portion sized (i.e. - 3/4 a pitcher) per day, then you are now consuming only 3/4 the daily recommended suggestions of nutrients and 1500 calories/day.
If that is your goal, then awesome. Just wanted to clarify any possible confusion, and make sure you are fine with the reduced nutrients and calories you are now consuming per day.
