Okay, I haven't tried it, but I cannot imagine having to pay anything to learn about it. This is what I found online:
"A woman, Kim, tweaked the Atkin's Diet to work more effectively and faster. (Kim + Atkin's = Kimkin's.) It is a hugely popular diet among people who are having difficulty losing with Atkin's, so I thought of you. Here it is:
KIMKINS DIET:
Up to 20 total carbs (not net)
Up to 3 cups salad type veggies 'or' Up to 2 cups salad veggies and 1/2 'cooked'
70-90 LEAN protein grams
No Low-carb products, treats, junk (pepperoni, pork rinds, protein bars) Bigtime stallers!!
NO alcohol
Just enough fat to make your menu work (don't overdo)

Kim also has a 3-5 day diet that is very strict, but known to cause quick and substantial weight loss and is a great jumpstart for the Kimkin's Diet/Low-carb diet. Here it is:
KIMMER'S 3-DAY EXPERIMENT:
As much lean protein as you desire-ONLY LEAN MEATS AND EGGS
Length of time is 3-5 days
Purpose is to experience 'real' ketosis (weight loss, no appetite)
Useful as springboard for other Low-carb programs
NO alcohol, No cheese, NO low-carb products, NO LC junk (pepperoni, pork rinds)
Basic condiments and spices OK (watch catsup and A1 sauce)
Very minimal use of fats (butter, oil, mayo) Less fat = faster weight loss"

Good luck!! By the way, lo carb may not be for everyone, but I once lost 30 lbs. doing it for about 4 months. I went off it and gained it allll back.
