I did it as a resident (well more forced due to work), but ended up dropping a ton of weight AFTER I stopped mostly bc I stopped eating like shit.
Last article I saw didn’t really show much of a benefit, but have also read the contrary. Everyone is different and metabolism as well. I’ve had some colleagues that swear by it, but if we’re being reeeeeeeally honest it’s probably more about what/how much is being thrown down the hatch more than 8/16, 10/14, etc.
