You're projecting an implementation onto an idea. It seems bad faith. The ability, or physical and emotional investment to lose weight isn't exactly insignificant, so you're right to emphasize that - projecting ignorance and malice on the idea rather than criticizing it's merits isn't helping though? $100 check contingent on nothing does seem like it could go wrong as well as being subjectively offensive, but you are the one who suggested that right? What would work best I wonder. I was lucky in the sense that my life's circumstances forced me to lose all my spare weight.
