aka the fatkins diet. This diet consists of fat and meat. You basically walk around all day like zombie and your breath smells like paint chips.
You will see these dieters eating pork rinds and craft singles for snacks. And if they happen to lose control and eat some bread they will beat themselves in the head for about an hour. This type of eating causes extreme water lose, so the dieter pisses every 5 minutes.
This diet is one of those yo-you diets as in "Yo I lost 20lbs, but my heart is the size of a horses heart now."
I've also heard this diet called the "Sourdough Jack Diet".
The typical diet looks like this. One stick of butter for breakfast, pigs feet for lunch and wheel of cheese from Randalls.
