Human meat tastes most like pork. That is why they call it “Long Pig” in the region.
Cannibalism is not as far from normal in SE Asia, as it is in the West. Even though it is a taboo, it is not so unthinkable. Societal attitudes tend more toward allowing/understanding resorting to cannibalism in extreme difficulty.
I had a heart to heart conversation with a Thai Army Captain in the 80’s over a bottle of Mekong whiskey, who discussed the hardships of warfare, isolated in the jungle. He emphasized that you absolutely had to be firm against any cannibalism of your combat dead - only the enemy. He confirmed the pork-like flavor.
As long as no animals were harmed...
I worked at a remote mining site in Indonesia. They would use the locals for help. Still living in bamboo huts and walking barefoot in the wet, rough and rough terrain. (They hated wearing the steel-toed rubber boots the mine gave them).
One of our helpers when we first met pointed at me and my buddy and in English said “VERY long pig!” and laughed. (We are both on the tall side.) The other helper spoke more English and explained it.
Well, at least at this restaurant it wasn’t cat or dog.
