You guys are living on nothing but the best? Can you come and bring me some food then? Or come cook for me? I just had a grisly goat shank that I had to eat because I bought the whole goat and it turned out gamey, but I'm not going to waste it. And earlier I had liver, which I barely choked down. Of course my freezer has some prime stuff, but if you are eating nose to tail, the truly desirable stuff is at most 40%. A good cook can make a lot of stuff appetizing though. Most of that gamey shank went into the stock pot, where it's the foundation for some good sauces.
A lot of paleo/primal folks do eat mainly prime cuts, but emulate the feast-famine thing by intermittently fasting. But no, I diet that's bacon and eggs and cheese and coffee with heavy cream three times a day is probably too rich and most people are going to get fat on it unless they are really really active.
Edit: it's interesting contrasting the two effective approaches on this thread. Travis has a more ascetic approach, whereas I'm always about hedonism. My diet allows me to enjoy super-rich restaurant meals a few times a week. My approach is pretty similar to food critic Josh Ozersky in the fasting part. Otherwise, I've identified foods that satiate me effectively and allow me to enjoy food without overeating. Also, the main super-rich foods I eat are also super-expensive and expensive restaurants do not serve huge portions. I think identifying foods that spur overeating (peanut butter is a great example for me) or halt overeating (liver for me) is very important for building whatever strategy you use. I'm about 1/3 fasting 1/3 simple mediocre meals 1/3 rich, but portion-controlled meals.
