I can't tell if you're being serious or not, so I will note for other readers that there is a lot of irony in saying this about Seth. His most public experiments were the ingestion of large quantities of olive oil for appetite control and daily butter consumption to aid sleep. A more appropriate sentiment might be to salute Seth for his radical health experiments, and the great risks he assumed in performing them on himself.
On the other hand, there is little doubt that overwhelming ingestion of anything will kill you. I'm not sure if it is too much or how long he kept it up, but 60g of butter sounds a lot to me.
So the traditional wisdom from what I remember is 20% fat, 30% protein and 50% carbs. 1000 calories a day from carbs means 250 grams of carbs a day. That sounds like a lot too.
In that, he was like us all. Unlike many of us, he was open minded and brave enough to experiment.
Report of the death of a genuinely good scientist, is a cruddy way to start a day. We should have a site rule that this kind of thing is only permissible after 5pm or something.
