Dar,

The fat fast is only for people who are very metabolically resistant -- the people who lose neither pounds nor inches on plain induction. From your stats you appear to be losing, so I wouldn't suggest you go there. If you want to read about it, it's in chapter 20 of DANDR (pgs 272-274 in my edition.)

The meat fast is also a stall breaker that (at least in my opinion) should only be resorted to if you're really stalled -- that is, if you've lost no weight and no inches for at least six weeks or more. And it's just what it sounds like -- you eat meat and fat, and nothing else. Fresh meat, not processed (no bacon, ham, sausage, etc.) cooked any way you like it. You can use fat in the preparation, and as a condiment, and you can eat the fat on your meat.

Of the two, I think the meat fast is a healthier idea than the fat fast, but if you're losing weight at all, I think it's better to just stick to the program.

Hope this helps.
