Even if that was true, that’s assuming your diet consists of only dairy. No beans, grains, meat, eggs… You could easily say the same for the bug powder.

However if you’re going to eat a diet based on one thing, make that thing dairy. It does contain all the nutrients required to grow a calf at a massive rate, and a human as well. In my youth I did the GOMAD diet for awhile to put on bulk, and the results were incredible. Milk is close to an optimal food, it evolved to be exactly that.
