Technically a fast-mimicking diet would be: ad-libitum fat, barely sufficient protein (such that protein recycling is maintained --- no idea how to calculate this individually), near-zero (ie. only trace) carbohydrate. I suppose zero protein would most mimick fasting if done for just a few weeks tops but once all degenerate/damaged/mutated/malfunctioning proteins have been degraded for protein recycling or gluconeogenesis, lean tissue gets catabolized and this isn't desirable.) So sounds like:
- a normal-size piece of meat or a box of eggs (or whatever concoctions the vegetationists prefer)
- unlimited ghee/tallow/lard (or whatever oils one's belief system suggests)
- water or 0kcal drinks
- and if prolonged over more than a week or 2, perhaps micronutrient supplementation
Well, that sounds just like a ketogenic diet. They actually investigate keto alongside their fasting diet and find similar benefits in many areas, just not to as large a degree.
