The Freakin' Expensive Diet

Buy good quality food like unprocessed cheese, cookies made with real butter, fresh-baked bread, lean meats, extra-virgin olive oil, quality chocolate, avocados and non-iceberg lettuce(although iceberg is nice sometimes).
Eat smaller amounts because even though you are eating less, it tastes way better and is richer in nutrients.
Watch the pounds fly off (five so far).
Refuse to bow to the diet gods. Give them the finger.
Ironically, the special diet foods one can buy (Atkins, Southbeach, etc.) are even more expensive.
Here is a good article.
