It was not EAA that was able to induce ketosis, it was leucine. This was due to the high insulin secretion upregulating glycolysis (and thus the breakdown of glucose) while leucine itself would never turn into glucose (being a ketogenic amino acid). So pulsing leucine would cause glucose to be used and eventually depeleted, resulting in ketosis.
I am not sure if a pulse fast would induce ketosis faster than just regular fasting (to use a comparison). It does have a very high insulin seceretion rate and a high leucine content, but other amino acids could potentially turn into glucose. However limited.
Although I would think adding EAA or more leucine to the pulse fast would be futile. It is already loaded with it.
