Muscle testing is in the same category as Oujia boards, basically. Except in this, your subconscious is the spirit conjured, and your arm is the dial indicator. The practicioner is the seance administrator.
Through the practice, ideally, your subconscious "confirms" the substances that are of interest (aggravating allergies, or whatever) with the suggestive prompting. Its a little bit of hypnotic suggestion, and in theory can work, but not reliably, as there is a lot that can go wrong including one's relationship and fidelity with their own subconscious.
In a head to head double blind test of the muscle response and testing physiological Immunoglobulin G, there is no question that if IgG was detected, but muscle response fails, then we can dismiss the muscle test effect.
Keep in mind also this practice is also applied in a far more general sense than just this type of testing. In fact, any thought or idea is theoretically testable- any truth claim about anything, ever. Just like the Oujia board.
Experts in the discipline have published books making claims, like pic related. Here, the "score" is a muscle testing result while the subject "holds" the emotion in mind by focusing on it "compassion", etc. I do not know of any published test where this was performed on naive participants in a controlled setting.
The power of the human mind and the ways in which it can be provoked to strange behaviors are many. It could be that negative emotions, about distressing feelings, or the subconscious reaction to a suggestive prompt to reflect on a substance they might have reason to believe could harm them, can result in a subconscious physical reaction, which is an explanation that renders the phenomena explainable in terms of known scientific principles, but it is not considered a scientific discipline.
