My brother likes to say there is only ONE diet that always works. It's the Original South Beach Diet: vodka, cocaine and cigarettes. It's extremely effective but can only be used by the young and stupid and I am neither.
I still enjoy a little Stoli, Grey Goose, Kettle One or Absolut now and then but I haven't touched blow since sometime in the mid-80s and I kicked the cigarette habit around the same time back when they cost $1.25/pack.
I'll admit it's tempting because you definitely get results quick and it's so easy to do because when you're drunk or strung out on nose candy you don't even think of food and we all know that cigarettes kill your taste buds but I think I'll keep trying the old fashion tricks of eating healthy foods and moving my a$$.
Things were so much easier when I was young and stupid. What's the worst effective diet you've tried?
