One team is doing this for calorie restriction and fasting, and is putting a defined fasting / fasting mimicking protocol through the FDA process. http://www.eurekalert.org/pub_releases/2014-06/uosc-fts060214.php http://www.eurekalert.org/pub_releases/2014-06/uosc-fts06021... http://michelsonmedical.org/2014/12/26/igf-1-fasting-discussion-valter-longo/ http://michelsonmedical.org/2014/12/26/igf-1-fasting-discuss... https://news.usc.edu/82959/diet-that-mimics-fasting-appears-to-slow-aging/ https://news.usc.edu/82959/diet-that-mimics-fasting-appears-... That said, it is quite true that most of what is said and done in connection with diet is some variety of nonsense, driven by self-interest on the part of market participants.
