I posted earlier. I do my own 4-5 day prolon diet, all fresh food (except the Amy’s soups). Mostly veg, avocado, a few nuts. I have done it 4 times now and I think it’s helped me lose visceral fat plus shifted my way of thinking (like it’s not an emergency if I can’t eat; I no longer buy gross expensive food in an airport, for example). I also introduced some new vegan recipes into regular rotation.
