Traditional Chinese medicine is not credible (but this is not important)

Losing weight means reducing fat, and the general principle of reducing fat: absorption is less than consumption.

Does acupuncture reduce your absorption or increase your consumption?

Reduce absorption. If the food you eat remains the same, you can see whether the excretion will increase after acupuncture (if it cannot be absorbed, it will be excreted, but it is estimated that it will not)

Increase consumption, fat consumption is through aerobic and anaerobic ways, no matter which will release heat. Doing equipment exercise (mainly anaerobic) will sweat, and doing running (aerobic exercise) will also sweat, because fat burning produces heat, and the body should eliminate excess heat. As for acupuncture, I have never heard of anyone sweating all over after finishing it, or stimulating a certain acupoint, and the heat of the body runs away like deflation in minutes.
