My son is in treatment for Leukemia, and most patients lose large amounts of weight. He's also autistic and has food texture issues. Somehow he's good with potatoes (generally baked "fries") and milk with some infant formula mixed in. He's the only young (<5 YO) patient they've personally had that has gained weight during treatment, and the attribute it to his "milk and potato" diet. To be clear, he's continued growing, if not normally, something approximating normal, during his chemo. That's highly unusual. Anecdotal, but it's my experience.
