That sounds just like the snacks and appetizers I often make! I have been a "Somersizer" for over 12 years (fell off the wagon a few times, but regretted it enough to get back on). In Somersizing, you are separating meals, based on their carb content. And the carbs you do eat, in fact everything you eat, should never be beyond a certain number (on the glycemic index or glycemic load). So for the non-carb meals, they end up being a lot like an Atkins, or South Beach style meal.
The entire system is based on the effects of food on your blood sugar, and the specifics of digestion (in the way blood sugar will / won't be affected by the food you eat).
That means that when you are eating at Level 1, (whether it's a carb, or a protein meal) you will never get to eat potatoes, carrots, real chocolate, white pasta or any form of sugar, nor any "mixed" foods (nuts, avocado, seeds). It was a bit complex at first, so I followed one of their menu plans "to a T." It also prohibits what I call high-octane caffeine (coffee, soda, chocolate). I felt great hunger at first, even though I was allowed to eat as much protein as I felt like. After about 3-4 days, things improved a lot, and after the first 2 weeks, I knew this was IT....I felt sooo great....as I hadn't felt since my early twenties.
Now, it's a breeze. Even back when I started, I found my energy levels soaring when I ate this way. Now with my age, and more recent health concerns, I find that if I don't eat that way, my energy levels drop to rock bottom, I don't sleep well, and I get sick much more easily.
You can do "maintenance" with Level 2; that's when you can mix small portions of foods that would be a "no-no" in Level 1 - but this way of eating still concentrates on healthy choices; which means no white sugar, nor any white flour products, as they remain on the "don't eat" list.
It made me look for, and find out, when and how to eat healthier versions of my fave foods - like pasta, and how to introduce those higher-carb foods "safely." If I've been off the wagon, it takes about a month of eating this way, for the weight to start melting off again. But the energy returns much faster - within a few days.
I have been to WDW many times and maintained this way of eating - really easy in the quick-service food choices too; of course, on every trip, I try to include at least one important food category: a Mickey bar
I bought several of the recipe books, and there are soooo many websites from which to get hundreds more ideas of how to make different versions of foods you love. Easiest desserts: creme brulee and cheesecake. I've even found a great "bun" recipe to replace the bread you can't have with a protein meal, or for sandwiches. The quickest and easiest meals are what I call "stir-fry" or "sauteed" meals....some kind of meat, with some veggies thrown in towards the end. I like to cook, and like to find easy, healthy and cheap ways, to make the things I want anyway, in as healthy a way as I can find.
