I have been on the diet one meal a day(OMAD) for a while now and I was wondering if it is a healthy diet and if it is historically based. I researched and learned that the ancient romans(particularly the patrician class) ate one meal a day around noon or so. I got on this diet after I did keto for a while and lost a lot of weight(probably because of cutting back on added sugar), the main appeal was that you could "eat whatever you want" during the one meal because you would still be in a caloric deficit. Being on the diet I have neither gained or lost any weight but I feel as if it is not particularly that healthy.
As far as TCM goes I looked a bit into this diet and would qualify as a khapha person I believe. Is this diet healthier and does anyone have an accurate link to the perameters of such a diet? I've found some sources in which it is basically just glorified vegetarianism and would like to get an accurate picture of the diet. Also how many meals a day is recommended on TCM?
I have neglected asking about this for a while but my daemon lover and intuition keeps telling me my diet is shit so any help in finding a good satanic diet is appreciated.
