I feel that drug use was covered pretty well but poor health decisions was not.
A particular discussion point appeared today: https://fitness.stackexchange.com/questions/29376/maximum-weight-loss-in-72hrs
This specific question askes for advice on how to execute a known practice that, without medical support, can be very detrimental to health. There is also scope for people to give answers which could be detrimental to health.
Should we accept these questions about completing dangerous/unsafe practices with relation to exercise/diet as acceptable?
