Do acupuncture needles used for weight loss or weight gain break the fast of a fasting person?

Acupuncture is an ancient therapeutic method that does not introduce liquids into the body. A fasting person must abstain from food, drink, and sexual intercourse. Scholars have differed regarding the ruling on what enters the body through means other than the usual orifices for food and drink, such as injections. Non-nutritive medicinal injections do not break the fast of a fasting person, whereas nutritive injections do. Since acupuncture needles are not nutritive and do not introduce liquids into the body, they do not affect the fast, and it is permissible to use them for treatment.
