I think that fasting-mimicking diets are a way to potentially get some of these benefits through occasionally engaging these "slower speed" repair mechanisms without permanently living with bare minimum protein intake. But I also think that at this point so far we've seen fat, sugar, and then all carbohydrates villainized. I don't think that excessive protein is going to turn out to be a good idea either and it will likely also have its turn as villain, especially after all of these new high protein fad foods that are still highly processed junk run their course. People just need to balance their damn nutrients and eat whole foods. There aren't many real shortcuts to health, but we're just desperate to find them due to time poor societies obsessed with hyper-optimization.
