RE: Black Bagging
It is VERY dangerous! The only weight you lose is water which is not real weight loss. It goes straight back on again when you drink. You are simply risking overheating your body and people are on record as dying from this practice.
This is probably the worst stupid fitness fad there is as it is so dangerous. At least most other things are stupid but relatively harmless, but this can kill you. Anyone who recommends this should be banned from working in the fitness industry in my opinion.
