The exception that proves the rule, I guess. What a silly saying.

He is talking about pretty high intake of fat, though. His initial experiment involved going from 224 grams of fat per day to 329 grams. A few years ago I did a 4:1 ketogenic ratio experiment on myself, like they do for kids with epilepsy, that's about 90 percent calories as fat,. I was eating around 2500 calories a day,that was to appetite, that's about 250 grams of fat per day. 329 grams a day--that would be an overfeeding experiment for me. Which is what maybe makes it more of a hack to trick your doctor/insurance, rather than a practical intervention. It works, maybe, because it is overfeeding--and greatly reduces the liver's role of supplying triglycerides to various tissues.
