May I be so bold to suggest that those who justify and seek permission/absolution with regards to their drug of choice are the same ones who thought WLS was a cure? That the sleeve would do the fighting for them?
When I went to Mexicali for my WLS Dr. Campos made an analogy that really stuck in my head.
Summarizing the analogy:
Losing weight, especially for the obese, is like a table with 4 legs. Two of the legs are WLS. The 3rd leg is choosing good fuel to put in your body as opposed to crap. The 4th leg is exercising. Get off your rear and move more.
If you take any of those legs away from the table, the table does not function as well as it could/should.
