I would seriously not be surprised to find that fat people have starved to death without their fat cells releasing fat, and blinded by preconceptions, nobody managed to notice or note down when this occurred. But I would expect that to be rare - most people, if their body tells them they're starving to death, will eat. This gets cited as weakness of will.

What outcomes would this metabolic hypothesis predict for obese people who undergo gastric bypass surgeries which render them physically incapable of eating much? What percentage of these patients would be expected to die of malnutrition? What effect on their body composition would be expected?

After working out the predictions of this hypothesis, are they consistent with what actually happens?

One of my friends who'd had weight loss surgery found that her treatment for pneumonia didn't work until they figured out that she wasn't absorbing as much of her oral antibiotics as people without the surgery would. I expect that sort of error is fairly common.

I've heard that there's a 30% risk of alcoholism after WLS, and this is backed up by what I've heard anecdotally.

The usual theory is "trading one addiction for another", but it isn't proven that people who are get WLS are that likely to be addicted to food. I've heard that the surgery makes alcohol hit faster, and that makes it a more interesting drug. I've wondered whether alcohol is simply a very compact way of getting calories. Some people find they have less appetite after WLS, but some don't.
