yeah. but my original point was that if there is a very low cal version (let’s say 1000kcal), it would be easy to build the right ratio.
take a 2100 bag (the normal bag), mix with 1000kcal, divide into two separate containers, each containing a day’s worth of 1550kcal, with exactly the right proportion of nutrition (or as close as Jօylent comes to it)
take two 2100s and one 1000. mix and divide into three containers. 1733kcal each.
for more exact kcal results, you would need more exact ratios.
