The beneficial properties of sun rays (but not UVB rays in excess) are recognized by modern medicine. As a supplement though, not as a substitute for food. I did that kind of experiment when 20 (eating very little food) and I got extremely emaciated and sick. Someone else may be more successful, but so far nobody took up to the challenge….
Perhaps not. But with combination of sun rays , oxygen and the practice of higher Kriya; the goal may be in reach sooner then we imagine.
“When the spiritual center in the medulla (ajna chakra) is (thus) awakened, the mind becomes absorbed in the sacred sound of om, emanating from that center. A divine nectar-like current flows from the thousand petaled lotus, which causes the secretion of a fluid in the mouth that is pleasantly sweet and very vitalizing. Great yogis, by drinking this nectar, can live without eating, never feeling the slightest hunger.”
~ Paramahansa Yogananda
