Per wikipedia:
The shell game (also known as thimblerig, three shells and a pea, the old army game) is a public gambling game that challenges players to follow the movement of a marker hidden under one of several covers (shells). In practice, the game is almost always run as a confidence trick that uses sleight of hand to transfer the marker between covers. In confidence trick slang, this swindle is referred to as a short-con because it is quick and easy to pull off.

In this case, the markers are molecules that contribute to weight loss/maintenance, which appear to be being put in and out of different foods, and even in or out of the same foods but in different packaging (especially seasonal treats) or with different dates on them.
Since I lack access to a powerful, truthful AI engine that will help me identify these molecules myself, I am left playing the weight loss "shell game" along with everyone else. (I was reluctantly amused to notice after one Thanksgiving that some of these molecules appeared to have been in the canned, name-brand cranberry sauce.)
Right now, I'm trying out mixtures of cocoa, taurine (plain), isoleucine (plain), and grape seed extract (plain, but sprayed and processed in ways that I can't possibly find out). Taurine especially seems promising.
