Supplements would be an interesting v0.3 or perhaps appendix to her next plan. I am well aware of body builders consuming 500 grams of protein/day in the form of weird expensive powders. But I wonder as a supplement to the existing diet how it works mathematically to eat perhaps 5 grams instead of 500 grams of supplement "complete" protein powder per day and then maybe cheap out on the bulk plant protein by selecting some plant that's not a complete protein. Carried out to a logical extreme I wonder if it "works" financially and nutritionally at $1/day or whatever to just eat rice and pop a multivitamin and a very small protein shake every day.
