Summary
There is not enough coma slurry onboard to feed Grace once he makes it to Rocky's home planet, and Erid's scientists will only be able to invent human-safe vitamins so fast. But Rocky has been doing Capital R Research on his portable earth thinking machine. Extra calories can be stored as energy in the form of fat cells in humans, and Rocky has tons upon tons of extra calories in his fuel tanks. While it won't do much for the nutrient deficiencies, why not overconsume on purpose to store energy for later?
His human friend is hesitant to agree, but the logic is sound. Gaining some extra weight now isn't going to hurt once the starvation eventually starts.

Summary
The toll of listening to his friend waste way from malnutrition and make himself sick on taumoeba harms Rocky mentally almost as much as it does to Grace physically. He never wants to hear his friend vomit again, and he desperately wants him to stop sounding like skin stretched over bones. He'll do everything he can to make Grace healthy again.
