Gene:

It's absolutely personal preference: the fat factor is a matter of taste.  If it's too greasy for you, use less!

(You really only need enough to keep the potatoes and veggies from burning.  Also, you need to add a lot less fat when cooking with hamburger: if you're cooking with, say, chicken breasts (blech!) or even a lean cut of steak, you'll need more to balance that out.)

Another trick you can do is to start out by frying the hamburger enough to get some fat out of it, remove the meat, cook the potatoes and veggies in the fat instead of butter, and replace the meat near the end.  This is a bit more complicated, but everyone's tastes are different.  

The key is to make sure there's jsut enough fat so that you don't feel the need to douse it in mayonnaise or some other industrial product!

"1) That's a lot of breakfast. 2) It was delicious! 3) I ate the whole thing and didn't feel bloated at all. Now to see when I get hungry again."

I bet it takes you a while!  You're consuming a meal that's nutritionally complete, high in slowly-digesting protein...and despite that, doesn't have as many calories as you probably think.  (Three large eggs only contain 225 calories, half a potato is much less, and there's not much in the vegetables, either...most of the calories come from the meat and butter.)

Don't stress too much about reading Paleo books.  Some of them explain the science at great length, which I personally find intriguing -- but everything you need to know is in Eat Like A Predator.  

Meanwhile, as Paul said: welcome to Paleo, and eating like a predator.  It's been nearly three years since I wrote these articles, and I still eat this way.  Sometimes I still eat this specific dish!  (Often the Asian variant.)  Doing so has changed my life dramatically for the better, and I hope the same for you.

John:

I do that sometimes, too, for the flavor -- but industrial bacon is very high in omega-6, so I don't do it too often.  If I had better access to pastured pigs I'd certainly do it more!

Paul:

I've been eating a lot of mussels lately, as they're in season.  I found a delicious Tom Yum soup base: Steam the mussels, shuck them into a bowl, add water, add the paste and some fresh basil, nuke it until it's hot, and I suddenly have no urge to go out and eat Thai food anymore.

"Today I did my workout on a 22 hour fast, and then I didn't eat for another 3 hours, because I still didn't feel hungry.
I don't think I've ever gone that long without eating before. And it was effortless. I just wasn't hungry."

A substantial part of hunger is your body telling you "I need some nutrients from food that I'm not getting right now." People focus on the bad ingredients in junk food, but the more insidious problem is that it doesn't contain anything we need to live. You can drink all the Coca-Cola and eat all the Halloween candy you want -- but you'll end just as hungry as before, because your body still needs complete protein, vitamins, minerals, and a host of cofactors.

In contrast, the Scramble is extremely nutrient-dense (I know people who have lived off it for the better part of a year). As a result, many people, like yourself, find that they have to eat less food and/or less often.

Another great flavor combination, particularly with chicken, is honey, (gluten-free) soy sauce, and hot pepper flakes to taste, with just a tiny hint (go easy, far less than the basic recipe) of mustard and garlic. Try it and let me know what you think.

I'm glad you're seeing success! Congratulations, and welcome home.
