Orlistat. Look at Alli — very available to buy. A very common side effect is steatorrhea. Oily leakage/poops. But not like, “oops I gotta run to the bathroom” but like, a tiny bear down and oil shoots out your bum. There is a clear warning on it about malabsorption as well of fat soluble vitamins.

Having taken orlistat in low/intermittent doses, I can say it really matters what you eat fatty stuff with, on top of quantity. A regular "balanced" low-mid fat diet, and you're (well, I've been) okay.

If you eat a tub of ice cream as dinner, you're going to have a bad time.
