Hi Anonymous,
Below is a link to a number of references that consider the use of RUTF.
https://www.odi.org/sites/odi.org.uk/files/odi-assets/events-documents/4273.pdf
Of particular interest may be the SCN policy paper No 21
https://www.who.int/maternal_child_adolescent/documents/pdfs/fnb_v27n3_suppl.pdf?ua=1
Among those, the paper of Ann Ashworth particularly considers dosing of RUTF.
A guiding principle resulting from the consultation was that:
"When RUTF is given to children with severe malnutrition, 150 to 220 kcal/kg/day should be provided."
Of interest may also be the paper on the use of 'low-dose RUTF' for continued recovery once the child is no longer classified as SAM:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4672709/pdf/mcn0011-0859.pdf
Other discussions on RUTF dosage can be found on ENN:

I hope this helps,
