Breast milk is, on average, a little bit less than the amount of fat as 2% milk.

If you want Marisa to gain as much weight as possible from her breasts, you should make a tube leading from her breasts into her intestines, where the milk (and the fats) will get ingested as-is without any of it becoming waste.

Then the fun part comes in where you grope her as much as possible to make her lactate into the tubes. She'll swell herself up with her own breast milk!
