Akman, fat tissue grows, both because there's more triglycerides in there, and because there's more fat cells. Those cells are alive like any other cell. Simply cutting carbs cannot kill those new fat cells, and so they remain. Those new fat cells are also supported by new blood vessels, and they remain too. This is one reason you had to go to extremes to reach an otherwise unreachable body weight. But of course, you couldn't keep that up, since you couldn't endure the side effects. As well you didn't: You were making yourself sick. Don't despair, we'll be able to fix that soon enough. There's a trial for a new peptide drug called Adipotide, which reduces fat tissue physically such that there's fewer fat cells.

As for resistant starch, maybe you're right. But I see no anthropological rationale for its use every day. Every day use is only made possible by agriculture and world commerce, thus we are not adapted to use it every day. The same goes for any claim of benefits for the colon or anything else.
