In this study a simple toy model solution to the missing mass problem on galactic scales is reverse engineered from galactic data via imposing broad assumptions. It is shown that the toy model solution can be written in terms of baryonic quantities, that it is highly similar to pseudo-isothermal dark matter on galactic scales and can accommodate the same observations (on galactic scales). In this way the toy model solution is similar to MOND modified gravity in the Bekenstein-Milgrom formulation. However, where it differs is in the similarity to pseudo-isothermal dark matter and in the functional form. In loose terms it is shown that pseudo-isothermal dark matter can be written in terms of baryonic quantities and on a form that suggest it may be worth looking into a mechanism that can increase the magnitude of the post-Newtonian correction from general relativity for low accelerations.
