I'm not on it. Only did it strictly for about 4+ months. It did "fix" everything, or the elimination of things that caused problems did.
I ate a variety of meat and seafood. Also, dairy and organs. Beef alone would make me bored quickly as well.
But I did stay away from sauces and marinades. On that front, I was and still pretty much a "boring" one with just salt and butter most of the time. Occasionally, I use black pepper, paprika and other spices.
I'd say stay away from those artificial sauces that has sugar or worst yet corn syrup for as long as you can, but definitely the initial couple of months so your body can get used to burning fat instead of sugar.
