What are lazy ways to lose weight for someone who has only this as an aim. Obvious thoughts: eating a couple of tapeworms, becoming addicted to an opioid, eating far too many laxatives.

You could arrange to develop lymphocytic colitis. That’s a lot of fun. It results in getting diarrhea several times a day. After a while you don’t want to eat, either, since you know that’ll land you on The Pot for a spell. The downside is you lose a lot of nutrients, too. And of course if you eventually get over it the weight will bounce upwards like a super ball and you will weigh even more than before you got sick.
Have someone else lock you in a room with only a sink and a toilet. Don’t let them unlock the door for a week or two weeks or a month, depending on how much you want to lose.
Contract giardia. A friend of mine did it on a backpacking trip. It took 4 months to knock the bug out for good. In that time he dropped 40 pounds. He also produced the foulest farts I’ve ever had the misfortune to encounter.
Unfortunately, according to the gastro doctor I saw, nobody really knows where it comes from. It just is. They don’t really know how to stop it, either, except for large doses of Pepto Bismol for a couple of months often (but not always) works. If all else fails, Immodium provides temporary relief. It’s not likely to get any significant research funds real soon, either, since it’s comparatively rare, and treatable with OTC products.
