What do you think about the Ketogenic philosophy?
It is best explained in Youtube channels such as "What I've Learned" and Eric Berg (but beware of his and his peers' claims about honey, which in reality is worse than white sugar)
They concentrate about the dietetic part of this philosophy, but I guess there is more to it, like minimizing light in order to reduce cortisol release.
I do recommend listening to most of what they say, while applying some consideration/discretion.
