My guess is that everyone has the same weight control system, it's just the parameter values that vary from person to person (and that differ between men and women). When SLD isn't working for someone, I believe in most cases it will turn out that they just need a larger "dose" of the diet -- they need to consume more set-point-lowering calories/day.
Here is one way -- a way that I find pleasant and easy. It is a variation on the idea of crazy-spicing one's food (adding random flavors) that solves some of the problems associated with the original idea.
Here's a drink I make in my blender:
1. Crush about 1 cup of ice.
2. add 1-2 T half-and-half.
3. add 2 Splenda packets
4. add 2-4 T protein powder (flavored okay)
5. add approx 1/4 - 1/2 tsp of each of 4 or 5 randomly chosen spice blends
blend until smooth.
This makes a pleasant and satisfying drink. It tastes "spicy" -- not unpleasant at all.
The half-and-half and the protein powder supply calories, which will be in range 100-300. Which should be just as effective at appetite suppression as the same number of calories of ELOO.
I like this for two reasons, both of which improve on the simple idea of adding random spices to your food:
1. It is pleasant to drink. Unlike most foods, the pleasure doesn't come at all from the flavor. It comes from the creamy texture (supplied by the half-and-half), the protein taste (supplied by the protein powder), sweetness (from Splenda), saltiness (from the spice blends), and the liquid (ice). Each of these components produces a little bit of pleasure, which sum up. The whole food is constructed to provide the pleasure that the flavor fails to provide.
2. There is no sense of loss. This food is new to me so I don't have any expectation that it "should" taste better than this. I don't think: oh no, I am going to add spices and make it taste worse. I think this is what caused many people to reject crazy spicing; they don't want good foods to taste worse.
It is as healthy as you make it -- you can add almost anything to the basic mix, including fruit and cooked vegetables. The large amount of spices is very healthy -- spices are high in antioxidants, as I've mentioned in my blog
I've been doing this for about two weeks. Yesterday I bought a new container of protein powder. I came home intending to have a small dinner but it was hot so I wanted to have this drink before dinner to cool off. But after I made it and drank it I forgot about dinner.
If you try this I hope you'll post about the results.
